Question

unity2D中c#脚本调用rigidbody2d时报错，求大神告知！！！

如图，每次调用都会报如下错误

代码如下;

void FixedUpdate ()
{
// Cache the horizontal input.
float h = Input.GetAxis("Horizontal");

if(h * Rigidbody2D.velocity.x < maxSpeed)
Rigidbody2D.AddForce(Vector2.right * h * moveForce);
if(Mathf.Abs(Rigidbody2D.velocity.x) > maxSpeed)
Rigidbody2D.velocity = new Vector2(Mathf.Sign(Rigidbody2D.velocity.x) * maxSpeed, Rigidbody2D.velocity.y);

// If the player should jump...
if(jump)
{
Rigidbody2D.AddForce(new Vector2(0f, jumpForce));
jump = false;
}
}

楼楼我会了，是unity版本的问题，你把其中两句改成
if(Mathf.Abs(GetComponent<Rigidbody2D>().velocity.x) > maxSpeed)
GetComponent<Rigidbody2D>().velocity = new Vector2(Mathf.Sign(GetComponent<Rigidbody2D>().velocity.x) * maxSpeed, GetComponent<Rigidbody2D>().velocity.y);

就可以了
