Can anyone tell me if block materials are working properly in 1.8 build 11.14.3.1450? I try to set different material types in my Block class with:

 

super(Material.cloth);

 

For example, and then I go to see if my block will burn and it won't. It seems like I can't change the material of my blocks.

If you explore up the constructor stack, you'll find that material doesn't do much anymore. In particular, it does not determine flammability. If you want your new block to burn, then it should override class Block's getFlammability method:

 

    /**
     * Chance that fire will spread and consume this block.
     * 300 being a 100% chance, 0, being a 0% chance.
     *
     * @param world The current world
     * @param pos Block position in world
     * @param face The face that the fire is coming from
     * @return A number ranging from 0 to 300 relating used to determine if the block will be consumed by fire
     */
    public int getFlammability(IBlockAccess world, BlockPos pos, EnumFacing face)
    {
        return net.minecraft.init.Blocks.fire.getFlammability(this);
    }

 

Since Blocks.fire.getFlammability() is deprecated, I don't recommend tinkering with Blocks.fire.setFireInfo() (though it might do what you want for the time being).
