Topic: Game Programming / Object Depth [AS3]

If you break the problem down into pieces, you’ll see it’s not so daunting.
Here’s some pseudo-code on how you may want to start approaching the problem:

for each child of the current object (hint: numChildren)
     add the child to an array (hint: getChildAt)

sort the objects in the array based on their "y" property (hint: read up on sorting methods)
(alternate hint: check the manual page NineFiveThree posted and look up Array's built-in sort method)

for each object in the array
     set the index of the object to its new array position (hint: setChildIndex)

Those 3 steps should be nothing scary individually, and the overarching problem will just be a simple matter of connecting it all together.

ErlendHL is right, though; you’ll need some knowledge of Java.

From the API Overview page

The API supports ActionScript 2 & ActionScript 3, as well as Javascript. Other web plugins
(Unity, Java, etc) are supported through the use of the Javascript version of the API.

It’s highly recommended that you post samples or previous work in the thread.

Topic: Game Programming / Noob after some tips

Adobe’s ActionScript 3 Reference is your friend when you want to know all the properties and functions that are available to you.
For example, if you want to know all the functions the Math class offers, you have a nice list here:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/Math.html

As for math, you should definitely brush up on high school trigonometry.

Topic: Game Programming / collision

If you’re going to use a radius around the player to determine if the block is close enough, you’ll want to use the Pythagorean theorem (simply, a^2 + b^2 = c^2), and compare “c” with your radius.

First, create a constant variable that will hold the value of the radius (“hitTestRadius”, for example).

Now, you’ll need to set up the Pythagorean theorem in your code. “a” will be the difference in x position between the player and block, and “b” will be the difference in y position. Solving for “c” will give you the length of the hypotenuse of the imaginary triangle created by “a” and “b”.

Setting up the theorem in code will end up looking something like this:

deltaX = blockArray[i].x – character.x;

deltaY = blockArray[i].y – character.y;

blockDistance = Math.sqrt(Math.pow(deltaX, 2) + Math.pow(deltaY, 2));

Finally, you simply compare blockDistance with the radius you assigned your player (“hitTestRadius”). If blockDistance is smaller, it has passed your distance test, and you can allow it to perform the hitTestObject.

Fitting everything into your code, it’ll end up looking something like:

for(var i:int = 0; i < blockArray.length; i++)
{
	deltaX = blockArray[i].x - character.x;
	deltaY = blockArray[i].y - character.y;
	blockDistance = Math.sqrt(Math.pow(deltaX, 2) + Math.pow(deltaY, 2));
	if(blockDistance < hitTestRadius)
	{
		if (character.hitTestObject(blockArray[i]))
		{
			trace(“hit”);
		}
	}
}

Topic: Game Programming / collision

For starters, you’ll need an array to store all the instances of the violetBlock object.
Right now, you’re doing:

VioletBlock = new violetBlock();

and

if (character.hitTestObject(VioletBlock))

{

	trace(“hit”);

}

The problem with this is that VioletBlock represents only the most recently created instance of violetBlock.
As you create each new instance of violetBlock, you’ll need to store the current value of VioletBlock into some array (“blockArray”, for example), then iterate through the array, checking for a collision between the player and each instance of violetBlock.

This will change your code to:

VioletBlock = new violetBlock();

blockArray.push(VioletBlock);

and

for(var i:int = 0; i < blockArray.length; i++)

{

	if (character.hitTestObject(blockArray[i]))

	{

		trace(“hit”);

	}

}

Of course this will result in a lot of hitTests per frame, so you may want to consider optimizing the collision detection by either:

a) only performing a hitTest if the block is within a short distance from the player.
b) using simple math instead of hitTest by calculating the difference between the player and block’s x and y positions to determine if an overlap is occuring.

Topic: Game Programming / random for as3?(solved)

Please read the manual:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/Math.html

‘random()’ generates a number in the range 0 <= n < 1, so if you want a random number between 0 and 10, you would multiply the result by 10, as such:

Math.random() * 10;

Topic: Game Programming / [AS3] Game Key Events Not Responding [SOLVED]

Someone else might have more of an explanation, but this basically means the focus is set on something other than the game object.

A quick-fix is using this when you start the game:

stage.focus = this;

Topic: Game Programming / Advice just starting

It’s “addEventListener”, not “addeventlistener”.

Also, you can simplify “x = x – 10” into “x -= 10”.
