[1.6.4] How to change custom model render based on block metadata

[skullywag]

Hi all,

 

Im trying to add a block that "grows" using metadata (0 = just planted, 1 = slightly grown 2 = full grown). I have a model that contains all the shapes for all the states, I want to pick the ones to show with a switch/if, something like:

 

public void render(Entity entity, float f, float f1, float f2, float f3, float f4, float f5)
  {
    super.render(entity, f, f1, f2, f3, f4, f5);
    setRotationAngles(f, f1, f2, f3, f4, f5, entity);

    if(meta == 0)
    {
    	MainCrystal.render(f5);
    }
    if(meta == 1)
    {
    MainCrystal1.render(f5);
    OffShoot11.render(f5);
    OffShoot12.render(f5);
    OffShoot13.render(f5);
    }
    if(meta == 2)
    {
    MainCrystal2.render(f5);
    OffShoot21.render(f5);
    OffShoot22.render(f5);
    OffShoot23.render(f5);
    }

 

but im having trouble passing the metadata in from anywhere, Ive tried from my TileEntity Renderer class in the renderTileEntityAt method to no avail. Ive tried NBT, no luck.

 

The problem seems to be that if i print the entity passed in to renderTileEntityAt it seems to know where it is (x,y,z) it know what its blocktype is it however ALWAYS returns 0 for getBlockMetadata and blockMetadata.

 

Once ive solved this issue there is something else id like to ask on this subject but i wont muddy the waters here until this is solved as this is the one thats bugging me.

You....are not using a render function that is appropriate for blocks, AFAICT.  You should be using either ISimpleBlockRenderingHandler, which has this:

 

 public boolean renderWorldBlock(IBlockAccess world, int x, int y, int z, Block block, int modelId, RenderBlocks renderer) { }

 

With the world and coordinates you can request the metadata.

 

Or there's TileEntitySpecialRenderer, which has this:

 

public void renderTileEntityAt(TileEntity tileentity, double x, double y, double z, float f) { }

 

Which passes a reference to a TileEntity.

 

In any case, both Entity and TileEntity have a public object worldObj which has a reference to the world where you can request metadata from blocks.

Forgive me if im misunderstanding you but, the start of my renderer looks like this:

 

public class TileEntityCrystalRenderer extends TileEntitySpecialRenderer {
        
        private final ModelCustom model;
        
        public TileEntityCustomRenderer() {
                this.model = new ModelCustom ();
        }
                
        @Override
        public void renderTileEntityAt(TileEntity te, double x, double y, double z, float scale) 
        {     	
            GL11.glPushMatrix();

 

As per my OP if I put a print statement before that GL11 PushMatrix, both te.getBlockMetadata and te.blockMetadata return 0 all the time, even I place meta 1, 2 or 3. The render method I posted in the OP is in my model class.

Dont know what I did but realised I was getting meta 0 even when placing 1 2 or 3 and after id removed the renderer it was still happening, deleted and recreated my block class and now it works, albeit im getting openGL errors (stack overflow) but ill figure them out. (I hope)

 

Edit - ITS ALIVE, (forgot to pop twice in my renderat)
