Topic: Game Programming / [AS3] Getting function arguments from an array [Solved!]

what your looking for is the apply method;

pos.setup.apply(pos, [my arg array]);

Edit: my bad I got it in reverse

in as3 what you’re looking for is
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/statements.html#…(rest)parameter

function setup(…args):void{

	for(var i:String in args){

		trace(args[i]);

	}

}

if you’re using as2 it’s called restParam

try adding them as is first, and see what the filesize becomes. flash has comressed some huge files for me before. but if the filesize is too big, take Drakim’s advice and go with audacity, it’s super useful for a million things.

My mistake, I figured AS3 and C# are based off Java, that must be from where it came.

No lag here on chrome, on a decent PC.

Topic: Game Programming / One-way platforms

just use a velocity variable to move the player, if you’re making a platformer you should already have this and acceleration. You just check if the players velocity is going in the platform’s blocking direction.

sorta psuedo coding here…

public var velY:Number, gravity:Number;

public var onGround:Boolean

public init():void{

	onGround = false;

	gravity = 1;

	velY = 0;

}

public function update():void{

	y += velY;

	if(onGround && upPressed){

		velY = 15;

	} else if(!onGround){

		velY += gravity;

		// -- ONLY HIT IF FALLING

		if(hit(platform) && velY > 0){

			onGround = true;

			velY = 0;

		}

	}

}

Edit: no idea how to fix the strikethrough, velY = -15;

Topic: Game Programming / Show us a screenshot of what you're working on!

I think it’s alright for games to be purposely abrasive. as long as you know your doing it and you’re fine with it. it’s the closest thing to “punk” a videogame can be. You don’t tell Slayer not to yell when they sing, do you?

A XOR B is if(A != B)

Topic: Game Programming / XNA Team Development

First off, your school is behind, XNA is dead. But it’s still nice and I know people who still use it.

Second, screw the modules and projects, set up a git or some kind of svn. I’m assuming the modules are different states or games? you should all be changing the same library so your not recreating the same functionality.

Third, in windows Visual studio go to new project. in the pop up window find “online templates” on the bottom left, if you have XNA game Studio 4 on it you can see a bunch of small projects you can learn from

Topic: Game Programming / Collision detection fail

Floating point errors happen with adding or subtracting “close” values (.6+.3). I don’t think you’ll ever get a floating for subtracting a number from the same number, which is what your doing when the x position is on the left most tile, which is when the subtracting values are “closest”.

(x – x%w)/w should always give you an integer if both of those values are integers. I really just thought it looked bad

anyways I feel bad for hijacking the thread with such trivial matters. so I’ll post this again for OP. highly recommend this and the same authors vector tutorials.

Topic: Game Programming / Collision detection fail

i mentioned running three tests, those are the results of the three tests

and floating point errors are in every language not just flash

trace(20.19 – 20);// - 0.19000000000000128
trace(.9 – .3);// - 0.6000000000000001

Because this way you get an integer value rather than a floating point and don’t have to deal with decimals; The modulo will give you the extra you need to shave off the original number to get a perfect division of the second argument, so when you do divide you get a simple answer, and need no more becasue you only want to know which tile you are on, not the exact section of the tile, as that would be pointless

I argue the opposite, RTLs way can cause floating point rounding errors giving you 2.000000001 in rare cases, mine returns an actual int. plus mine is more readable, and faster. I ran 3 tests, my output values are in the comments

var i:int, t:int, x:int;

t = getTimer();
for (i = 0; i < 100000; i++)
x = (200 – 200 % 32) / 32;

trace(“test 1:”, getTimer() – t);// - 28, 28, 25

t = getTimer();
for (i = 0; i < 100000; i++)
x = int(200 / 32);

trace(“test 2:”, getTimer() – t);// - 17, 10, 9

t = getTimer();
for (i = 0; i < 100000; i++)
x = Math.round(200 / 32);

trace(“test 3:”, getTimer() – t);// - 24, 16, 17

even Math round is faster

I know it’s weird, but I’ve always pronounced like “flat” without the t, haha.

My cousin’s an animator and he calls it an “F-L-A.” I’m guessing that’s the right way to say it.

There’s no right way, man. i used to say “flah” but people snickered so I stopped.

Topic: Game Programming / Collision detection fail

The point is Hittest is slow, basic rect collision is super simple.

this is an old tutorial but the math is dead on

Topic: Game Programming / Game Demo, and a question.

Try to avoid raising difficulty by simply raising the values of enemies. try making different enemies, with different abilities. maybe certain enemies have soft spots you have to hit or they move in a pattern. games that just “generate” content are never as good as games with human designed waves and layouts.

Topic: Game Programming / Game Demo, and a question.

The game starts out too easy, and never gets harder. Can’t wait to see future development though.

P.S. you spelled “cost” wrong

Topic: Game Programming / GiTD [#32] Voting finished! [imp2]

So if everyone is criticizing I guess I’ll join in.

Note, I casted my vote above, already.

In no particular order:

Feeding Your Demons: You were my third place choice. Love the menu, love the concept, though you didn’t really hit the theme too well. It’s very hard to plan in these games, but maybe it’s because I’m bad at them. random moves would give me 12 combos that I never could have foreseen, and I never got any benefit from. overall, too luck based, and very easy to win.

Mr. Collector: I chose rock and nothing happened, which made me laugh. but still, the ability to customize the game didn’t over shadow the fact that there wasn’t much going on here.

Cat Burglar: Love the art, and the concept is entertainingly bizarre, but I could never manage to play games that made you wait, it seemed like the only way to win was to wait for the danger to go down so as not to wake her. the field of view system was nice, but there just wasn’t a lot of interesting gameplay.

Collectron: great style, you had a nice engine too, but far too little content, and almost no challenge. Just keep making levels and I’m sure I’ll love it. The in air controls were non-existent, which was frustrating.

The Collector: You almost seem to avoid the Jam’s theme in terms of gameplay, but I just plain like shooting people. Nice platformer physics. The game is too short, the shotgun is too weak, and there’s very little challenge, I’d like to stress the difference between challenge and difficulty. I felt that skill had little to do with my victories or my deaths.Edit: forget to mention the pain I get when I see pixel art rotated, please dont use pixel art if they are going to rotate.

Body Bagger: Love the art, I wish you could finish the comics. Your game revolved around the theme and had a unique take on it. the actuall gameplay got old pretty fast. It frustrated me that I would never collect them all, and that you basically lose if you fail to collect a certain one. It looks like you worked really hard on the game, but just failed to make the game play progress in any way.

Hunting Sim: Decent rpg with quite a bit to do, but generally not my cup of tea. As I said earlier, I’m not a fan of waiting.

Klecter: I really liked this, but it could have been a lot better. eventually the enemies form a singularity, so the game stops getting harder, the collectables are no where near frequent enough, half of the game I’m waiting for more to spawn, why not have 10 out at a time? I would also like to see a version where enemies can’t overlap.

Photo Collection: Nice simple game. but I don’t like waiting for things, it would be nice if there wee more things to photograph, and less time between appearances.

Forest of Death: tons of cool things with this game, great graphics, nice mechanics, really nailed the theme. but the weapons are totally pointless, its far simpler to run around and never shoot a skeleton. It takes way to many shot to kill them. The game was also too dark to see enemies right in front of me.

Surviving in the Wild: I love the concept of an edible island. and the game mechanics were nice, but the game was frustrating, you shouldn’t be able to eat your only means of progression. There’s no indication of what hurts you, and you die too quickly.

Topic: Game Programming / Tweening and adding child at same time

is the parent your adding it to rotating? you need to embed fonts for rotation, or something. does it show if you add it and then tween it?
