I am making a paintball gun which fires snowballs and when it hits the ground the block it hits changes to a coloured wool block. But i want this change to be temporary. Is there a way that after 5 seconds the wool goes back to normal? Heres my code. Code (Text): Material block = loc.getBlock().getType(); loc.getBlock().setType(Material.WOOL); loc.getBlock().setData((byte) woolcolour); loc.getBlock().setType(block); loc is the location of the block the snowball hits. Also, is there a way i could select the blocks around the block the snowball hits, so multiple blocks turn to wool, so it looks more like a real paintball.
