Psi

Psi is a mod created by Vazkii. It is themed around magical programming, being inspired by the Japanese web novel and anime Mahouka Koukou no Rettousei.

Psi allows action sequences, or spells, to be both created and executed in the Minecraft world. It has a leveling up mechanic, and much of the programming done requires the use of mathematics. Spells are created in the Spell Programmer, which has a drag-and-drop interface, but is nevertheless complicated.

Players are strongly recommended to have some knowledge of kinematics and trigonometry.
