Unity, Coordinates of the button-CodePudding

How to get the bottom left and top right corner of a button in screen coordinates if the button is on an Overlay Canvas? It should depend on screen.width and screen.height.

CodePudding user response：

You can use GetWorldCorners, when the canvas is an overlay canvas, the world positions are equal to screen positions.

var corners = new Vector3[4];
GetComponent<RectTransform>().GetWorldCorners(corners);

// corners[0]:  bottom-left
// corners[2]:  top-right

If your canvas is an screen camera canvas, you need to convert them with camera's WorldToScreenPoint method.
