is there a way i can check if a certain item is in the smeltable slot in the furnace. (where iron ore, gold ore, etc goes). I'm trying to make a block change its texture depending on what item is in the smeltable slot. I tried an if statement like:

if (tile.inv[0] == new ItemStack(Item.wheat))

{

    bindTextureByName("/****/****/*********.png");

}

 

where "tile" is the tileEntity, "inv" is the inventory slot, and "[0]" is the smeltable slot.

instead of changing the texture to what i want it just changes it to a glitchy terrain.png.

For the compare you'll want to compare the IDs of the items or (even better) use isItemEqual, rather than comparing the address of the new item stack against a different one in your tile.

 

if(tile.inv[0].isItemEqual(new ItemStack(Item.wheat)) .....

 

or maybe

 

if(tile.inv[0].itemID == Item.wheat.shiftedIndex)....

 

Check TileEntityFurnace (functions canSmelt and smeltItem) for examples of checking what is where.

 

Not sure about your texture problem.
