在平面/立方体世界空间中获取鼠标单击位置

Question

Hi2,

This seems to be an easy problem to fix., but i still cannot figure it on my own.

I need to be able to find the position of my mouse click at the 3D plane at world space which corresponding to plane's scale.

For example: if i click the point a in my game view., it should return me 0,0f The MainCamera however, can do move around.


and then if click point C it should return me a Vector2 which (i believe) should correspond with the scaling of the 3d object


and clicking inside the 3D plane, should once again return me a Vector2 according to the Object's scaling.

I know that i can use Input.mousePosition but it just return me the mouse position without any relation to the plane object itself.

There is " Camera.ScreenToWorldPoint" that converts to in game position. here: https://docs.unity3d.com/2018.4/Documentation/ScriptReference/Camera.ScreenToWorldPoint.html
