MissileROTVar makes homing projectiles weave. It applies to every projectile whose BulletType has a ROT above zero.

A homing projectile’s turn rate swings over a 15-frame cycle. At the bottom of the cycle the projectile turns at its ROT, and at the top it turns at ROT × (1 + 2 × MissileROTVar). A larger value makes the weave wider. At 0 the projectile turns at its ROT throughout and flies without weaving.

Each projectile starts the cycle at a different point, so missiles launched together do not weave in step.

Two cases override the cycle:

  • A projectile fired by a weapon whose Speed is below 40 does not turn until it has accelerated to that speed.
  • A projectile within one cell of its target turns 1.5 times as fast as the cycle allows.

Steered flight explains how the turn rate steers the projectile.
