Creating projectiles

Now we'll create the projectile class. It will have a sprite that's pulled from the spritesheet, and it will move from left to right at a fixed velocity.

Creating the class

To start, make a new class in the source directory named Projectile. Here it is for reference:

package;

class TestSprite2 extends FlxSprite
{
  public function new() 
  {
    super();
  }
}

Adding imports

Next, add the imports:

import flixel.util.loaders.TexturePackerData;
import flixel.FlxSprite;

Creating variables

Now add the variables we'll be using:

private var texturePackerData:TexturePackerData;
private var speed:Float = 2000;

The speed value will be used to determine the velocity of the projectile.

Displaying the sprite and setting the velocity

After the super call in the constructor, add these lines:

texturePackerData = new TexturePackerData(AssetPaths.ingameSprites__json, 	  AssetPaths.ingameSprites__png);
loadGraphicFromTexture(texturePackerData, false, "projectile.png");
this.velocity.x = speed;

Setting...
