Change Vanilla mobs size?

[Insane96MCP]

I just want to make something like bigger zombies when they're stronger, or creepers bigger when they have more explosion power.

 

Not only the hitbox, the model too

I'm not a computer right now to check but there used to be a method called pre render callback where you could do things like GL11 scaling to make entity model render bigger.

So, I managed to mess up with RenderLivingEvent

 

@SubscribeEvent
public static void EventRenderLivingPre(RenderLivingEvent.Pre<EntityLivingBase> event) {
  if (event.getEntity() instanceof EntityZombie) {
  	GL11.glPushMatrix();
  	GL11.glScalef(2.0f, 2.0f, 2.0f);
  }
}

@SubscribeEvent
public static void EventRenderLivingPost(RenderLivingEvent.Post<EntityLivingBase> event) {
  if (event.getEntity() instanceof EntityZombie) {
  	GL11.glPopMatrix();
  }
}

But I'm obiviously doing something wrong

But as I'm writing I'm thinking that to do what I want to do, I have to replace the RendererZombie (or whatever mob) with mine and change size there.

Scale using GL changes the position/origin as well. So you need to sort that out. You also need to update it's serverside bounding box.

 

Use https://www.programcreek.com/java-api-examples/index.php?class=org.lwjgl.opengl.GL11&method=glTranslatef for changing position.

But the mob is not bigger ... and when seen from above it disapears

Are you changing it on clientside or serverside? 

 

Also use GLStateManager and not the raw GL calls.

 

Edit: Look at RenderGiantZombie as an example.

The event is called clientside only, right?

As an example to use GLStateManager?
