A_FaceTarget

A_FaceTarget [(float angle[, float pitch])]

Changes the calling actor's angle to face its current target.

If angle is specified, then the calling actor cannot turn by more than said angle. (A value of 0 is interpreted as unlimited angle.) However, the SHADOW flag has no effect in such case.

If pitch is specified to a value no greater than 180, then the calling actor's pitch is adjusted by up to said value to face its current target. (A value of 0 is interpreted as unlimited angle; and technically a pitch change will never be greater than 180 degrees.)

Examples

Almost every monster uses this function before it shoots at its target.

Missile:
  TROO EF 8 A_FaceTarget
  TROO G 6 A_TroopAttack  // See DoomImpBall
  goto See
