[SOLVED] How to make a block that has multiple layers for textures

[TheTrollingTrollguy]

Hey guys, it's me again with another crazy idea. How can I make my block have multiple texture layers like the grass block has. What I want to do is to have a base texture on all sides, then have transparent textures on all sides(which in my case will be an arrow) and then the last layer for textures is on that kinda adds some "shadows" on the block, it is transparent too(it will represend the block age, which I have with my tile entity).

So I have 3 layers:

1. base texture

2. arrow or line texture(transparent)

3. "shadows" texture(transparent)

 

So what do I need to do? Add some methods to my block class, or make a renderer for my block? Tell me.

You'll probably need custom renderer for that (class that implements ISimpleBlockRenderingHandler). I have similar block in my mod so you can have a look at these files:

 

Custom renderer:

https://github.com/EnkeyMC/morelights/blob/master/renderers/LampRenderer.java

 

Block class:

https://github.com/EnkeyMC/morelights/blob/master/block/BlockOverlayLamp.java

 

Hope it helps

 

EDIT:

I am basically rendering the block in two passes (0 & 1). In each pass is rendered different block (different texture) and the block is taking the base texture from blocks around itself.

I did mine a little differently, but same idea.

I didn't bother with passes, I just rendered twice.

And are you rendering transparent textures? Because I think you need to render in two passes if you are rendering transparent texture and solid one on top of each other.

Yes, and it works just fine.

 

Edit:

The reason you would need to render in the second pass is if you don't want the block obscuring other blocks ("ambient occlusion").  But a fully solid block with an overlay don't give two shits if stuff behind it isn't rendered when the overlay is rendered.  It can't obscure itself, so the pass number is irrelevant.

Removed the code since the problem is "solved".

Hi

 

The symptom you're seeing is generally caused by the lighting settings.  I'm not sure why you're seeing this because your call to renderStandardBlocks immediately before the renderFaceYpos should have set the lighting up properly already.  Some more info here (but it's pretty complicated and I'm not sure it will help to be honest)

It looks to me like you don't actually need to render the arrow separately from the asphalt block?  Why not just draw the arrow and block as a single icon?

see here

Just override getIcon to return the faces you want (with/without arrow, and pointing in correct direction).

 

You'll need a custom renderer for your item like Enkey said.

Nah, It looks like I'm just going to do textures that already have arrows on them, because of the lighting. Reasons why I wanted to have them separate is because I'm already using the arrow texture on a block so I wanted just to "stick" it to another block and to have less textures in my mod file after I release the new update. Since I can't really make any progress because of the lighting I'm switching back to my old system. Thanks for the help!
