Since I announced yesterday that I’d finally earned my first $100 payout through the GameMaker Marketplace, I dropped my price on all paid assets to $0.99. I had another purchase today, so to celebrate that, I decided to adjust the terms of the sale.
The payday celebration sale will continue through 4/10/17 as planned.
For each paid purchase I get during the sale, I will extend the sale by one day.
Update, I had another sale today, 4/11/17, which will extend the discounts another day.
So as of right now, the sale on all my paid assets will last until 4/12/2017.
As a child of the 1970’s, I’ve been attracted to arcade video games since I was tall enough to reach the controls. This was 1981-84, during the heyday of the arcade’s Golden Age, a time when games like Pac Man, Dig Dug, and Galaga were new, hot, and everywhere. Grocery stores, gas stations, seemingly anyplace people might spend time, you’d find a couple of arcade games, ready to suck the quarters out of anyone who passed by.
Just slightly older than these games were the ever-popular Space Invaders, and its evolutionary next step, Galaxian. Although these titles were top shelf games in their day, I found that I didn’t enjoy them very much.
Space Invaders was just frustratingly slow at first, but then sped up to an unfair pace by the end, and I could never manage to destroy that last invader on the first wave. You had to have perfect aim to hit it, and it moved so fast it was seemingly impossible to track, so you had to be lucky. If you missed, the slow-moving missile took forever to disappear at the top of the screen, and you couldn’t fire again until it did. Usually this delay meant your death, as the hyper-paced final invader would reach the ground, ending your game. Plus, it was black and white. It felt old. I respected it — even then I could tell that it was a important game — but grudgingly, I had to say that I just didn’t enjoy it that much, although I wouldn’t have admitted it to anyone back then.
Galaxian, too, was a game I found too slow and frustrating to play at arcades. It seemed like the next step in the vertical space shooter. Graphics were now in color. A formation of aliens marched back and forth across the screen, but this time instead of descending toward the earth, they stayed at the top of the screen, while one by one, or in pairs, individuals would peel off from their formation and dive bomb you. Their bullet patterns and flight paths seemed to make it all but certain that they would hit you if you didn’t hit them first. I could usually survive for a while, maybe clear a screen, but it never failed that if I happened to miss a dive bombing enemy, it would corner me in the side of the screen and crash into me, or hit me with too many bullets to dodge. You could always dodge one, but there’d always be another one following up, and your first dodge would put you right in its path. It seemed unfair, and so, not very fun. I always gravitated toward the games that I could last a bit longer on, so I could get my money’s worth out of my quarters.
I had a cousin who owned an Atari 5200, and played Galaxian on it once or twice while visiting them. The 5200 port was a very faithful reproduction of the arcade experience, not exactly arcade-perfect, but nearly so. I still didn’t care much for it, because it suffered from the same shortcomings. It wasn’t as bad to lose at home, since it cost nothing, but I still preferred to play games that felt fair.
It never entered into my mind that maybe I just wasn’t very good at Space Invaders or Galaxian. But probably, I was. Ok, not probably. I sucked. But in my defense, I was like 6, and just tall enough to reach the stick and see the screen. But back then, I blamed arcade games for being “greedy” in contrast to home consoles, which seemed to reward players with longer games that were still challenging, but more fun because they weren’t so brutally ass-kicking hard.
I never played Galaxian on the Atari 2600 back in the day. I’d played the 5200 version and was impressed with its arcade-quality graphics, and I remember seeing the pictures on the back of the box on the 2600 version, and being unimpressed. Since I never particularly enjoyed the game, I didn’t have any interest in owning it on the 2600, never knew any kids who had it in their collection, and so never played it. At some point, we had an Atari 7800, which had Galaga, the sequel to Galaxian, and one of my very favorite games, so I played a lot of that.
I’m not sure when exactly, but at some point I picked up a copy of the 2600 port of Galaxian, probably a few years ago. I recognized it was a significant title in videogame history, and so I wanted it for my collection, despite not having favorable memories of it from its heyday.
I finally got around to playing it today, and came away very impressed. Here’s a video review so you can see what it’s like:
The 2600 port plays much better than I remember the arcade. The motion is extremely fluid, which, considering the limitations of the Atari 2600 hardware, is nothing short of amazing. Maybe I’m just better at videogames than I was at ages 5-8, but I found that the game felt very fair, with divebombing enemies that are actually dodge-able. I’m sure, the horizontal aspect ratio of the screen plays into this somewhat, as you have more room to dodge, and also your shots that miss take less time to leave the screen, meaning that you can fire follow-up shots that much faster.
I was always a fan of vertical shooters of the Atari 2600, my favorites being Megamania, Phoenix, Threshold, and Tac-Scan, and Space Invaders. Galaxian is every bit as good as the best of these, and is still fun to play even now.
Playing Galaxian tonight, I found that my strategy was different from how I played the arcade original some 35 years ago. My old strategy was to try to shoot the enemies still in formation. They were easier to hit, since they didn’t swoop or shoot at you, and it seemed to me safer to eliminate them before they could turn into a threat. I’d try to shoot the divebombing aliens as they flew over me, and dodge out of the way of them and their shots, but mostly I concentrated on blowing away he ranks of Galaxians in formation, much as I approached Space Invaders.
My new strategy was much more successful, and rewarding: I ignored the galaxians in formation, since they don’t do anything that can hurt me, and focused on the divebombing aliens. It turns out, this has many advantages. First, by focusing on the divebombers, you are focusing on the only thing in the game that can threaten you. Shooting them is a much more reliable way to avoid them than dodging. You will need to dodge sometimes, but if you focus on developing skill in shooting the moving enemies, it gets pretty easy to pick them off before they can collide with you. The green Galaxians are simple, slow moving, and easy to hit. The purple ones are harder to hit, but with a little bit of practice the timing becomes easily mastered.
Hitting divebombing enemies in mid-flight makes you safer in two ways: enemies are destroyed before they’re low enough to collide with you, and they can’y get all their shots off. Typically, you’ll hit them as they cross ahead of you, and so you’ll be moving in the same direction, to track them, and the shots they do get off will fall harmlessly behind you, and by destroying the alien as it passes directly above you, you prevent it from getting ahead of you where it can drop bombs that would be dangerous to you.
Additionally, by hitting them as they’re diving toward you, your shot has less distance to travel, which means that you can get off more shots — since you can have only one shot on the screen at a time, when they hit something low on the screen, the shots don’t have as far to travel, meaning they hit the target sooner, meaning that your bullet is consumed and you can then fire another shot more quickly. If you miss one of the bombers, you might still end up hitting one of the galaxians still in formation, especially early in the stage, which isn’t so bad either. But the lower your shots are when they connect with an enemy, the faster you can shoot.
This in turn sets up a rapid flow of firing, hitting a dive bomber, then hitting the next dive bomber with a rapid follow-up shot. Once mastered, you can mow through the entire formation in quick succession in this manner. This turns out to be very enjoyable. You feel more skillful, since you’re targeting the fast-moving enemies, getting more points for them, and it looks more risky, since you’re often hitting the enemies pretty low on the screen, when it looks like they’re most dangerous — but at the same time you’re actually playing the least risky style of play. Of course, that’s what skill is — finding the right pattern of actions to minimize your risk, while doing what looks the most daring.
It’s clever, because the more intuitive way to avoid risk would be to try to avoid the dangerous enemies and attack the enemies that aren’t a threat. But counter-intuitively, when you focus on the dangerous enemies, and take the aggressive approach of destroying them rather than running from them, it minimizes the risk they pose to you, while the enemies that aren’t a threat remain a non-threat.
At this point, I recognized what a truly well-designed game Galaxian for the Atari 2600 is. I’m curious to see whether this strategy applies to arcade Galaxian. Since I don’t have ready access to an arcade with Galaxian in it, the next best thing is to watch a YouTube video of a skilled player.
And it looks like this is indeed the strategy to employ, although this player also has enough time to target plenty of enemies still in formation. I think the 2600 and arcade versions are different enough in their game play that they feel like different enough that while the basic strategies are more or less the same, the specifics are different. In the arcade, there’s much more space between the bottom of the screen, where you are, and the top of the screen, where the enemy formation is. But ultimately, I think the Atari port gives you less time to target the enemies in formation, forcing you to spend most of your time focusing on the swooping divebombing enemies.
In any case, Atari 2600 Galaxian is a fantastic game, and if you’re into vertical shooters is a must have, being one of the finest examples of the genre on the Atari, as well as an outstanding port of a historic and classic game.
In creating my last tutorial and demo, I needed to calculate the rolling average for the fps so I could measure performance differences between Instance Pooling and Create-Destroy.
It turned out that the functions for setting up a rolling average were pretty simple, yet were a pain to do well. So once I got them working, I decided to make them into an asset for GameMaker: Marketplace, so they’ll be easy to re-use in any project, with any series of numeric values, and so I can share them with the community.
Calculating a rolling average over a series of streaming values is now simplified by these new functions:
This is a milestone for Ludum Dare, as they are running this jam on their new website, ldjam.com. The old website had served admirably for many years, but lately the scale of the event has exceeded its capability, and the ad hoc customizations to the wordpress site were such that it was difficult to maintain the site. The new site will be a welcome renovation as well as a new foundation from which a better LD will be possible.
I am planning on using GameMaker Studio 1.4 one last time (probably) for LD37, because GMS2 is still in beta, and YYG have not yet released the HTML5 module, and I prefer to be able to create a HTML5 build of my project so that more people can play it. I’m looking forward to learning what the theme will be.
KBTester is a utility/demo I made to help out with coding your keyboard_check routines. It is born out of frustration and necessity for handling certain inputs from a very fundamental input device for computer games, the standard keyboard, which are not supported out of the box.
If you program keyboard input in your games, you’ll find that, for most keys on a computer’s keyboard, you can use vk_constants and ord(letter)… but for some odd reason YYG didn’t create a vk_constant for every key on the keyboard, and don’t plan to. Not only that, but there are certain keys that don’t return the right value for ord() to work with keyboard_check.
For example, say you want to check if the period key is pressed. You might think that you can do keyboard_check(vk_period) but to your surprise, there is no vk_period constant defined in GML. So, then it must be that you need to do keyboard_check(ord(“.”)) only… it doesn’t work!
That’s because ord(“.”) returns a value of 46. But for some reason, if you want keboard_check() to return true when the period key is pressed, you need to check for the value 190. Why? Why are certain keys on the standard keyboard treated as second-class citizens? Because, sadly it’s not in YYG’s vision to improve keyboard support.
To paraphrase a certain “Evil YoYo Games Employee” who commented on my suggestions for ways the current keyboard support badly needs to be improved:
<paraphrase>Why should we improve keyboard support when you can just research what codes map to your keyboard keys, make an extension that has a few constants in it, and then hope that these will work with all keyboards and all target platforms? Just code it once and then put it up on the Marketplace. Now that the marketplace exists to provide stopgap coverage of GM:S shortcomings, we don’t have to pay our own programmers to fix those holes anymore.</paraphrase>
So, I guess we’re supposed to figure out the numbers and then code some constants for the missing vk_constants, and use those. This, despite the helpfile recommending against using hardcoded numeric values in keyboard_check because you never know if it’ll work on the target platform if it’s not Windows/Mac/Ubuntu:
NOTE: These functions are designed for Windows/Mac/Ubuntu desktop platforms only. You may find some of the in-built variables and constants aren’t valid on other platforms and many of the functions won’t work on mobiles.
Now, each key is normally defined by a number, called the ascii code, and you can directly input this number into these functions and they will work fine… But, as it’s a bit difficult to remember so many numbers and the relationship that they have with your keyboard, GameMaker: Studio has a series of constants for the most used keyboard special keys and a special function ord() to return the number from ordinary typed characters (either letters or numbers).
The implication is that, YYG seem to be saying, “Despite the promise of GM:S to be a development environment that supports multiple target platforms, we didn’t see the need to ensure that your code will run the same on all target platforms we support, or all region/localities, or with all keyboard layouts. After looking into it we decided it was too hard for us to deal with, so we’re passing it along to you to figure out for yourself. So just be aware that these may or may not work on all platforms, and that’s all the info we’re going to give you about that. You’re on your own to figure out how to solve keyboard input from any platforms that don’t work with our keyboard input functions.”
Well, for whatever reason, YYG doesn’t provide FULL keyboard coverage between ord() and vk_constants, and it’s not in their vision to address this shortcoming, so I guess you’re going to have to go out and find some reference that will tell you what numbers represent what key, and then hope they still work.
In the meantime, you can use KBTester, press a key, and get the answer without having to hunt the info down on the internet and hope it’s correct. If you’re having trouble getting keyboard_check to work, and need to verify that the magic number you’re using is indeed the right one, you can run KBTester. Press the key you want to use, and KBTester will tell you the value that GameMaker sees when it is pressed.
I don’t need a bigger screen, OK? I need a screen that will fit comfortably in my pocket. My front hip pocket to be exact. The dimensions of the Samsung Galaxy S5are about as big as I can go. Really, the S2 was more comfortable.
I don’t need a thinner phone. I need a phone that feels comfortable in the hand.
I don’t need a thinner phone. I need a phone with ample battery, such that I don’t need to charge for several *days*, despite heavy use of the device. If you made the phone phone that was inch thick, and all that extra space was battery, and I could go a week without charging, that would be AMAZING.
While we’re at it, I would also really like intelligent battery management. I would like apps that need to use the network to not talk to the network directly, but talk to a network handler, which will determine if/when to allow the data to be transmitted. I can then configure the network manager to either not allow any transmission (like airplane mode; saving maximum battery), or allow all transmissions at any time (fastest response but lousy battery), or burst mode (leaving the transmitters off most of the time, but waking up and reconnecting every N minutes, sending/receiving data that has accumulated in that time, or when I request it).
Lastly, tell network providers to quit bundling apps with their phones. I don’t want or need so many of them, and there’s no way to uninstall the ones that are baked into the firmware. I can figure out what I need and install it. If I’m upgrading or migrating from an old phone, it should carry all that stuff over, with all my settings and data anyway. There’s no need to bundle anything. Just provide me with a bare phone.
And tell network providers that they must roll out security updates in a timely fashion (days, not months) so that users aren’t left vulnerable. Frequent, more granular updates rather than one or two monolithic updates before support for my handset model is dropped entirely, would be great.
Following up on my earlierposts on this subject, after long delays, the new GameMaker Community Forums is now live. The archive of the old GMC forums is still at its old url. YoYo Games are offering a 10% discount coupon as a token of appreciation to users who’ve put up with the lengthy downtime as the old forums were transitioned and the new forums took unexpectedly long to bring online. It’s good to have writable forums once again.
[Editor’s note: I started writing this post shortly after the last episode of season six aired, back in April… then promptly forgot about it, until season seven started last week. In light of the outpouring of fans and critics complaining about the season’s first episode, I decided to finish up and publish.]
I’m thinking about this season’s last episode of The Walking Dead. The big season ending cliffhanger in which we’re finally introduced to Negan, and he brutally beats (likely kills) one of the central cast members, and we’re left to wonder who until next season.
My feelings on the show are pretty mixed. I definitely like TWD, overall, and moreover, I am predisposed to like it. But I increasingly find myself wondering why as the show grinds on. Mainly, I think, it comes down to the characters that I’ve grown attached to: Glenn, Daryl, Carol being my favorites. They’re played by great actors, and viewers have grown very attached to them over six seasons. But what really hooked me was the strength of the writing in the first season, and the realism of the situations that the survivors faced, and the realism of their responses to it.
There was a serious external threat represented by the zombie outbreak and the collapse of civilization, but also internal struggles as people who probably would ordinarily never cooperate or interact with each other were thrust together by circumstances and forced to cooperate for a chance at survival. Disagreements and conflicts and strained loyalties. And the choices the characters made had real, life or death consequences. People died on the show, just about every episode, and they were often characters who you cared about.
But also, there were the pragmatic, immediate matters of survival at hand. What tactics work against zombies? What about a huge number of zombies? Forgetting about zombies, how do you do basic survival when civilization has collapsed — how do you eat? Stay warm? Take care of your health and hygeine?
As the show has worn on, though, these things that made it interesting have been replaced or receeded into irrelevance. It’s taken for granted that they know how to survive. They are shown foraging, farming, and scavenging, but we never really see them starving, or shivering, or too weak to go on. They’ve gotten competent with fighting and know anti-zombie tactics so well that zombies are no longer a threat unless the show decides to make a stealth zombie come out of nowhere for a deus ex machina kill. Death spares the central cast, making it tame and predictable.
[[PUT SOMETHING HERE ABOUT HOW THE SHOW AT ONE TIME GAVE A FALSE HOPE OF FIGURING OUT WHAT WAS CAUSING THE ZOMBIE OUTBREAK AND STOPPING IT]]
For a time, the series dangled some hope of answers and a resolution. We might find out what caused the zombie apocalypse. There might even be a way to cure it. But those hopes were blown up in a memorable episode a few years ago, and since then, apart from a false hope in the form of Eugene’s story that he needed to get to Washington, D.C., there really hasn’t been any sense of direction. The cast have not been on a quest to go anywhere or accomplish anything, it’s just been an endless sequence of running into people, running into zombies, running into people, running into zombies, and most everyone they run into ends up dying before too long, but the central cast had started to take on an aura of invincibility.
Encounters with the living follow a formula: Either the other group is brutal and threatening, cannot be trusted, ever, and must therefore be destroyed; or, the other group is soft and weak, cannot be relied on, and must be exploited until their inexplicably stable pocket of civilization is overrun by either zombies or stronger people. We pick up a few new cast members who have the potential of making it with the protagonist group, but these people are all marked for death, and the idea is that we’re supposed to start to develop feelings for them before the show rips them from us, usually in some meaningless, almost accidental incident that is there mostly for its shock or horror value, which due to the contrived and predictable nature of the setup, is always diminished and weaker than intended.
Because there’s not enough time to allow for meaningful character development at the pace the writers want the show to take, we mostly don’t get any. There’s hints of possibility that go unexplored as the main plot hurtles past at highway speed. In many ways it feels like what makes it to broadcast is the “digest version” of a larger, richer story that we’ll never get to see. I guess that’s why the book is always better than the screenplay production. Yet, it’s frustrating. And if they could simply choose to take the time, you know they could make the show 10 times better than it ends up being. Essentially every character’s arc is left unfinished, or truncated. This could be the tragedy that we crave if it’s in full development only to be cut short by an untimely, horrible death. But despite the cornucopia of death that the show loves to present to us, almost none of it seems to hit us that way — the recent death of the doctor character just as she’s starting to come into her own being one notable exception, but all the more glaring due to its singularity.
Also, the central characters are so safe that the show’s writers are forced to have them make stupid decisions for no apparent reason. Carol’s most recent apparent death wish and her decision to leave the group again, for no real good reason, being the latest example of this. But we see it again and again, and it feels like it’s only an excuse to put a central character in danger, only to have the show pull its punches and spare them from harm.
Now, with the Negan kills ????? cliffhanger, the show is promising us a bloody, brutal end to one of our favorite characters. I’ve admired The Walking Dead for its willingness to kill characters, as TV shows so seldom often do. It was far more interesting to watch TWD knowing that it would not pull punches and spare a character just because they were a fan favorite. But this cliffhanger, I think, is too much for me. It’s like the show is using the spectacle of execution as entertainment. Death on the show wasn’t for entertainment, at least not for me, it was there to illustrate that TWD was a different sort of show, where, just like in real life, death doesn’t play fair, and that made me feel like characters were really in peril whenever there was danger.
I haven’t watched the first episode of Season 7 still, and after reading a lot of people’s responses to it, I’m not sure that I want to.
