On Infantry/Vehicle/Aircraft/Building Types

Determines the Rate Of Turn of this object and/or its turret, if applicable. Bigger number = faster turn.

On Projectiles

A non-zero value means this projectile can home-in on its target. A value of 0 disables homing behavior and leaves the projectile to fly straight. Note that this method of straight flight is buggy in TS and ever since.

• ROT 1 appears to be a special case:
  • On aircraft, a projectile with an ROT of 1 will fire the weapon in a strafing pattern of single projectiles until the target either moves out of range or the aircraft itself flies directly over and past the target regardless of what the weapons burst count is.
  • On other objects, a projectile with a ROT of 1 will be fired in a straight line on their target (seen on the Cyborg Commando in Tiberian Sun).
  • Setting ROT to 1 appears to make the projectile default to a high acceleration, meaning that it will be fired at a low speed and accelerate as it moves towards its target, though modifying the Acceleration tag can prevent this in order to generate a smother flight.
  • Projectiles with an ROT of 1 are known to act strangely when fired at certain angles or distances. They will sometimes "overshoot" their target and fly on past the map boundaries, but re-enter the map later, hitting their target. Other unusual behaviour has been observed regarding flight characteristics, especially when an ROT of 1 is coupled with AA=yes or Inaccurate=yes / FlakScatter=yes, though this might hold true for all projectiles with a ROT greater than 0 and Inaccurate or FlakScatter (needs testing). The most obscure effects are obtained by firing an inaccurate / flakscattering projectile with an ROT of 1 from aircraft, which will give an extreme form of the "Circling Missile bug".

Mind that:

• setting a predefined flight path (via Template:TTL / Template:TTL and similar) ignores the ROT setting.

• setting Template:TTL forces the projectile to respect the weapon's Template:TTL setting, meaning it can only follow a target so long as the target is within the weapon's range from the location it was fired from. Reaching the limits of this range will cause the projectile to detonate. If "Ranged=" is set to "no", the projectile will follow its target indefinitely until it is either triggered to detonate (by hitting the target, Proxy fuse or maybe some other trigger mechanic that can be coded) or is destroyed (say by Firestorm) or the the target is destroyed by other means, which will cause the projectile to instantly detonate (which is true for any homing projectile).
