Rotates a vector current
towards target
.
This function is similar to MoveTowards except that the vector is treated as a direction rather
than a position. The current
vector will be rotated round toward the target
direction by an angle
of maxRadiansDelta
, although it will land exactly on the target rather than overshoot. If the magnitudes
of current
and target
are different then the magnitude of the result will be linearly interpolated during
the rotation. If a negative value is used for maxRadiansDelta
, the vector will rotate away from target/
until it is pointing in exactly the opposite direction, then stop.
