Does anyone have the links to the videos? It seems my browser/internet/or this update to the forums killed the embedded videos and I can't watch them here, nor can I extract the links to manually do so myself.
also for SkylordJoel I looked at how the vanilla furnace works in 1.7.2 (you can look in the referenced libraries in that version) and this code snippet might help
* Update which block the furnace is using depending on whether or not it is burning
public static void updateFurnaceBlockState(boolean p_149931_0_, World p_149931_1_, int p_149931_2_, int p_149931_3_, int p_149931_4_)
int l = p_149931_1_.getBlockMetadata(p_149931_2_, p_149931_3_, p_149931_4_);
TileEntity tileentity = p_149931_1_.getTileEntity(p_149931_2_, p_149931_3_, p_149931_4_);
field_149934_M = true;
