Unity-如何在相機看到運動物體時停止運動物體

Question

這只是我想做的一件簡單的事情。 我讓我的立方體游戲對象旋轉，因此我想使其旋轉，以便當攝像機看到立方體時，它停止旋轉。 如果您能引導我朝正確的方向前進，我將不勝感激。 謝謝

public class cubeMove : MonoBehaviour, MoveObject
{
public Renderer rend;

    public void Update () {

    rend = GetComponent<Renderer>();
    stopWhenSeen();      
}
public void move()
{
    transform.Rotate(new Vector3(15, 30, 45) * Time.deltaTime);
}
public void stopWhenSeen()
{
    if (rend.enabled == false)
    {
        move();
    }
}

}

Answer 1

實現OnBecameVisible和OnBecameInvisible MonoBehaviour的消息：

private visible = false ;

// OnBecameVisible is called when the renderer became visible by any camera. INCLUDING YOUR EDITOR CAMERA
void OnBecameVisible()
{
    visible = true ;
}

// OnBecameInvisible is called when the renderer is no longer visible by any camera. INCLUDING YOUR EDITOR CAMERA
void OnBecameInvisible()
{
    visible = false;
}

void Update()
{
    if( !visible )
        move() ;
}

public void move()
{
    transform.Rotate(new Vector3(15, 30, 45) * Time.deltaTime);
}

您可以在更新方法中嘗試.isVisible bool。

這是一個帶有其他建議的主題：
