Unity坐标系的转换—世界坐标转为UI坐标

世界坐标转为UI坐标

直接调用WorldToAnchorPos，传入对应的参数返回UGUI坐标

publicstaticVector2WorldToAnchorPos(Vector3 worldPos,Camera mainCamera =null,Vector2? canvasSize =null){if(mainCamera ==null)
            mainCamera = Camera.main;Vector2 screenPos = mainCamera.WorldToScreenPoint(worldPos);returnScreenToAnchorPos(screenPos);}publicstaticVector2ScreenToAnchorPos(Vector3 screenPos,Vector2? canvasSize =null){Vector2 screenPos2;
        screenPos2.x = screenPos.x -(Screen.width /2f);
        screenPos2.y = screenPos.y -(Screen.height /2f);Vector2 anchorPos;if(canvasSize==null){
            anchorPos.x =(screenPos2.x / Screen.width)* CanvasSize.x;
            anchorPos.y =(screenPos2.y / Screen.height)* CanvasSize.y;}else{
            anchorPos.x =(screenPos2.x / Screen.width)* canvasSize.Value.x;
            anchorPos.y =(screenPos2.y / Screen.height)* canvasSize.Value.y;}return anchorPos;}
