[Solved]Projectiles and stuff

#1

Ok as advised in my last topic i’m splitting this up into only parts i need help with so i need help adding projectiles(bullets,bombs,etc). I already added the collision checks for them from the tutorial on the main site but i have no idea how to make the player and the enemy shoot and also im trying to implement bombs for to use for one the support npc’s but i couldn’t find anything on bombs.

A projectile is a custom entity. Start making the entity with the collision handle. Add movement (usually a prefixed direction with a constant speed).

To add them just make it spawn every time a key goes down in the Player position looking and going to the same direction.

PS: If you are new in AS3 i highly recommend you to make some tutorials first.

#3

I know but i couldn’t find any.

Try searching “ActionScript 3 tutorial” in any search engine like Google. Literally millions of results will apear :wink:

#5

Ok i tried that but i didn’t get a tutorial that actually taught what i needed it only showed some tutorials on angle calculation n stuff like that which i won’t need since the player will only be shooting straight ahead.

Look tutorials for how to move a particle and particle collision. Just modifying the x and yvalue of an entity it moves.

#7

Did that but there primarily particles for rain fire snow stars and all the background stuff. Like everything except bullets and bomb…do you know a specific tutorial the you used to learn how?

#8

Ok after a really long search i found a good tutorial and got it. Here is some sample code if anyone else new has the same problem as me. package

{
	import net.flashpunk.Entity;
	import net.flashpunk.FP;
    import net.flashpunk.graphics.Spritemap;
	public class Bullet extends Entity
	{
		[Embed(source = "../assets/bullet.png")]
		public static const BULLET:Class;
		private var sprites:Spritemap;
		private var moveX:Number = 0;
		private var moveY:Number = 0;
		public function Bullet()
		{
			sprites = new Spritemap(BULLET, 10, 10);
			sprites.add("idle", [0, 1, 2], 12, true);
			sprites.play("idle");
			graphic = sprites;
			setHitbox(10, 10);
			type = "bullet";
		}
        public function setMovement(_x:Number = 0, _y:Number = 0):void
		{
			moveX = _x;
			moveY = _y;
		}
 
		override public function update():void
		{
			x += moveX * FP.elapsed;
			y += moveY * FP.elapsed;
			if (x > FP.camera.x + FP.width + 50 || x < FP.camera.x - 50 || y < - 50 || y > FP.height + 50) {
				destroy();
			}
		}
		public function destroy():void
		{
			
			FP.world.recycle(this);
		}
	}
}
