%5Bbreaking Changes%5D What'S Different Between 0.1 Beta And 0.2 Beta

Well there's not much to do to update your mod to 0.2-beta.

Here's an example:

The old code:

public class EntityTest extends EntityCreature implements IAnimated
 {
     protected AnimationHandler animHandler = CraftStudioApi.getNewAnimationHandler(this);

     public EntityTest(World par1World) {
         super(par1World);
         this.animHandler.addAnim(Mod_Test.MODID, "position", "craftstudio_api_test", true);
     }
    ...
 }

The new code:

public class EntityTest extends EntityCreature implements IAnimated
 {
     protected static AnimationHandler animHandler = CraftStudioApi.getNewAnimationHandler(EntityTest.class);
 
     static {
         EntityTest.animHandler.addAnim(Mod_Test.MODID, "position", "craftstudio_api_test", true);
     }

     public EntityTest(World par1World) {
         super(par1World);
         EntityTest.animHandler.addAnimated(this);
     }
    ...
 }

As you can see there's three main changes:

The AnimationHandler is now static and take the Entity class as argument.
As the AnimationHandler is the same for all Entity of a type you must add animation in a static block to avoid adding an animation multiple times.
You still need to tell the AnimationHandler that your entity is animated, so you must add the addAnimated() with the Entity that is animated (this here).
