Custom Cauldron - Rendering Issue?

[PitchBright]

Hi Guys,

 

I'm trying to create my own cauldron so that it will do 2 things differently than the vanilla cauldron.

 

1) Hold 16 levels of water instead of 4

2) Render the 16 levels of water

 

I have been able to accomplish this with ease, by testing my edits on the base class files, so I know for sure what stuff to change in my copy-and-pastes. My main problem is I don't quite understand how to make my own Custom Cauldron block override the RenderBlocks.java method that vanilla Cauldron uses.

 

Basically what happens is... I can place my Custom Cauldron, and it behaves as though it has 16 levels of water... but the actual rendering method being called is the vanilla Cauldron's, in RenderBlocks.java... so the water tile levels show up, behave the way vanilla's cauldron does.

 

I've created a RenderCustomCauldron class that I would like BlockCustomCauldron to use... but I must be overlooking something fairly simple... like registering something in the Registry or Proxies.

 

Or perhaps I'm not understanding how to override the method in RenderBlocks.java.

 

I would really appreciate any insights or help you can offer on this. Here's my code, if you don't mind taking a look at it:

[Ebilkill]

The getRenderType shouldn't return the same number as the cauldron, but should return the number your custom renderer has.

[PitchBright]

I don't think my custom renderer has a number. Can you please explain to me what I need to do in order to resolve what code I'm missing in my files.

 

Thanks!

[Maexx]

In your Block Class don't return 24 for "getRenderType()" but "RenderKhufuCauldron.renderID"

Then add this to your RenderKhufuCauldron class:

 

public static final int renderID =  RenderingRegistry.getNextAvailableRenderId();

 

 

This will get a free renderID for the renderer and the "getRenderType()" in your Block Class will return it as the render for your block.
