public static Vector3 RotateTowards (Vector3 current, Vector3 target, float maxRadiansDelta, float maxMagnitudeDelta);

Parameters

currentThe vector being managed.
targetThe vector.
maxRadiansDeltaThe maximum angle in radians allowed for this rotation.
maxMagnitudeDeltaThe maximum allowed change in vector magnitude for this rotation.

Returns

Vector3 The location that RotateTowards generates.

Description

Поворот vector'a от current к /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 stops.

void Update() { // Determine which direction to rotate towards Vector3 targetDirection = target.position - transform.position;

// The step size is equal to speed times frame time. float singleStep = speed * Time.deltaTime;

// Rotate the forward vector towards the target direction by one step Vector3 newDirection = Vector3.RotateTowards(transform.forward, targetDirection, singleStep, 0.0f);

// Draw a ray pointing at our target in Debug.DrawRay(transform.position, newDirection, Color.red);

// Calculate a rotation a step closer to the target and applies rotation to this object transform.rotation = Quaternion.LookRotation(newDirection); } }
