Blends multiple steering behaviors into one, and returns a weighted acceleration from their calculations. Blends multiple steering behaviors into one, and returns a weighted acceleration from their calculations. Appends a behavior to the internal array along with its weight. Returns the internal GSAITargetAcceleration. Returns the behavior at the specified index, or null if none was found. Returns the behavior's weight at the specified index, or null if none was found. Returns how many behaviors are added. Removed the behavior at the specified index.
