I only have experience using [urlhttp://www.creationkit.com/GetHeadingAngle_-_ObjectReference]GetHeadingAngle[/url], not GetHeadingAngle, but from the descriptions, they work the same. I don't know what the problem is exactly, since I don't know how you set up your conditions. Let's assume that you have a cloak ability to apply a spell to anything within a whole cell (such as this example). So I'll give you a few examples of some conditions and explain what happens. S GetHeadingAngle [TARGET] >= 25 In the case of magic effects, the "subject" is the actor that was hit by the spell or magic effect. Target is the one who cast the spell. Turning to the right means turning in a positive direction, turning to the left means turning in a negative direction. So that means the condition is saying, "Only apply this magic effect on the spell target if the spell caster is to the right of the target, but not so close that the target can see the caster with a 25 degree turn." S GetHeadingAngle [TARGET] < 25 The condition is saying, "Only apply this magic effect on the spell target if the spell caster is less than a 25 degree angle from the target's right. So if the caster is in front or to the left of the target, apply the magic effect. If the target can only see the caster after turning 25 degrees or more to the right, don't apply the magic effect." S GetHeadingAngle [TARGET] < 25 AND
S GetHeadingAngle [TARGET] > -25 The condition is saying, "Only apply this magic effect on the spell target if the spell caster is less than a 25 degree angle left or right of the spell target. In other words, apply this magic effect only if the spell target is facing in the general direction of the caster." If you had the same conditions as above, but you checked "Switch Subject and Target" (or whatever that checkbox is called), then the condition is saying, "Only apply this magic effect on the spell target if the spell target is less than a 25 degree angle left or right of the spell caster. In other words, apply this magic effect only if the spell caster is facing in the general direction of the target."
