Unity 射击例子

脚本要与放靶心图片的的物体相关联

//靶心图片
	public Texture texture;
	//射击信息
	private string info;
	void OnGUI()
	{
		//计算准心图片的坐标
		Rect rect = new Rect(Input.mousePosition.x - (texture.width >>1),Screen.height - Input.mousePosition.y - (texture.height >> 1),texture.width,texture.height);
		//绘制准心贴图
		GUI.DrawTexture(rect,texture);
		//输出射击结果
		GUILayout.Label(info + "Position:"+Input.mousePosition);
		
		
	}
	
	void Update ()
	{
		//创建从摄像机位置与鼠标位置之间的射线
		Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
		RaycastHit hit;
		//判断是否打中
		if(Physics.Raycast(ray,out hit))
		{
			info = "YES";
		}
		else
		{
			info = "NO";
		}
	}
