Transform 放在Update中
transform.Translate();
----------------------------------------------------------------------------
Rigidbody. 物理放在FixedUpdate中
addfroce ---vehicle like movement with slow build up of speed。车辆一样的运动,慢慢积累速度
rb.AddForce();
velocity
Veter2 move;
rb.velocity= new Veter2(move.x*speed*Time.deltaTime,rb.velocity.y);
rb.velocity= new Veter2(move.x*speed*Time.deltaTime,move.y*speed*Time.deltaTime);=rb.velocity=move*speed*Time.deltaTime;
MovePosition
rb.MovePosition(rb.position+(move*speed*Time.delaTime));
注意点:
Gravity does not work with MovePosition ----Velocity is reset to Zero every function call
Moveposition does not take friction into account---Moveposition不考虑摩擦力
when to use movepositon over velocity
- want to move on x and y axis. ---想要在x轴和y轴上移动
- do not need friction ---不需要摩擦
- do not have a need for gravity---不需要重力
- want collision detection ---想要碰撞检测
