Custom furnace won't change texture when burning (or active)

[Jeerdus]

Good day,

I tried everything and I can't seem to get it to work.

I have made a custom furnace and I want to make it change texture when active (things are "smelting"). I tried everything that I can do; tried vanilla code, tried some tutorials, but none of them worked.

 

Here's the actual block code:

Hi

 

The vanilla furnace changes its blockID when it becomes active, in updateFurnaceBlockState.  Have you used breakpoints or logging to check whether the ID is changing properly?  And that your TileEntity.updateEntity() being called properly?

But you shouldn't replicate that. With forge it's totally sufficient to change the metadata. Vanilla changes the blockId because the vanilla code doesn't allow different light levels based on metadata, but forge does.

 

So...what should we do then?
