Tick copy test

The Minecraft game engine progresses through time in steps called "ticks". In each second there are 20 "game ticks". There will never be more than 20 game ticks in a second, however, if there are less than 20 this means the game is lagging. Each tick includes processing most things in your Minecraft world. All ticks are calculated on the server that is running the world. As the server is calculating the ticks even if your FPS drops, your Minecraft world can still run at full speed. On the other hand, even if you have high FPS your TPS (ticks per second) can be below 20 making things in the world sluggish (such as mobs moving).
