I want to be able to click/touch anywhere in a grid square and snap a screen space UI element (popup menu) to the center of that square.
I have an empty gameobject that has a grid with each box equal to one world unit (see screenshot bellow). The gameobject has a transform, a box collider, and script on it. I can snap to a local position in the grid with the code below, but I can’t seem to figure out how to convert a Local point to Screen Space point. How can I find the coordinates to snap a Screen Space UI element to the center of a grid square that is in local world units?
Thanks for the help
< TL;DR >
This code works for locally positioned gameobject, how do I get from here to screen space UI element snapped to the center of a grid square?
// Snaps a local positioned gameobject to the center of a grid square. // Each grid square is one world unit. // midPoint = 0.5f; transform.position = new Vector3(Mathf.FloorToInt(localPoint.x) + midPoint, Mathf.FloorToInt(localPoint.y) + midPoint, localPoint.z);
