A tick is a tiny unit of time within Minecraft – 0.05 seconds, that works as a kind of in-game clock for events.Īny chunks that are currently loaded (or otherwise active due to certain blocks being maintained) receive a chunk tick, every tick – provided their centers are within 128 blocks of the player. To understand how quickly grass can spread, you need to understand random ticks and chunk ticks.Ī chunk is a large area of blocks in minecraft (16 x 16 x 16). If a grass block is random ticked (explained below), it checks 4 random blocks within the 3x3x5 radius and adds dirt to any blocks which are able to receive grass.
