Unity3D笔记

1. 方向键方向基于摄像机朝向变化

float moveHorizontal = Input.GetAxis ("Horizontal");
float moveVertival = Input.GetAxis ("Vertical");
/*cam是摄像机的transfrom*/
Vector3 camForward = Vector3.Scale(cam.forward, new Vector3(1, 0, 1)).normalized;
Vector3 move = (moveVertival * camForward + moveHorizontal * cam.right);
rb.AddForce (move * speed);
