镜头平滑跟随代码(用于赛车游戏)

王者再临

老外发布的一个摄像机跟随代码，主要用于赛车游戏中，比官方默认的那个效果要更强大些，下面是详细功能简介：

Here's another smooth camera script. Designed to follow a car smoothly and give you the ability to zoom out when the car is moving. Hope someone makes use of it.

    target = self explanatory
    distance = Standard distance to follow object
    height = The height of the camera
    heightDamping = Smooth out the height position
    lookAtHeight = An offset of the target
    parentRigidbody = Used to determine how far the camera should zoom out when the car moves forward
    rotationSnapTime = The time it takes to snap back to original rotation
    distanceSnapTime = The time it takes to snap back to the original distance or the zoomed distance (depending on speed of parentRigidyBody)
    distanceMultiplier = Make this around 0.1f for a small zoom out or 0.5f for a large zoom (depending on the speed of your rigidbody)

Looks best when you place the target transform on the front axle

30.         currentRotationAngle = transform.eulerAngles.y;
    
31.         currentRotationAngle = Mathf.SmoothDampAngle(currentRotationAngle, wantedRotationAngle, ref yVelocity, rotationSnapTime);
    
32.         currentHeight = Mathf.Lerp(currentHeight, wantedHeight, heightDamping * Time.deltaTime);
    
33.         wantedPosition = target.position;
    
34.         wantedPosition.y = currentHeight;
    
35.         usedDistance = Mathf.SmoothDampAngle(usedDistance, distance + (parentRigidbody.velocity.magnitude * distanceMultiplier), ref zVelocity, distanceSnapTime);
    
36.         wantedPosition += Quaternion.Euler(0, currentRotationAngle, 0) * new Vector3(0, 0, -usedDistance);
    
37.         transform.position = wantedPosition;
    
38.         transform.LookAt(target.position + lookAtVector);
    
39.     }
    
40. }
