TASK_FOLLOW_TO_OFFSET_OF_ENTITY

TASK_FOLLOW_TO_OFFSET_OF_ENTITY(Ped follower, Ped target, float offsetX, float offsetY, float offsetZ, float var1, float var2, float minDist, BOOL b1, BOOL b2, BOOL walkOnly, BOOL b3, BOOL b4)

follower - The ped you want to follow somebody
target - The ped you want the follow to follow
offsetX,Y,Z - Offset from target the follower will stand
minDist - Minimum distance the follower can be from the target (-1 for auto, 50f is max)
walkOnly - if true the follower can only walk

var1: found in scripts (-1, 1f, 1.2f, 2f, 2.5f )
var2: found in scripts (-1, 1.0)

Unsure what they both do, I cannot seem to find any difference when raising and 
lowering them. Maybe you need to have one of the Booleans active for them to take effect?
