I have a 2d game where I want to display UI element perfectly aligned to specific gameObjects.
I have an ortographic camera and I used to Camera.main.WorldToScreenPoint() function giving it the gameobject position modified, for instance, by +1 on X component to get the UI element on its perfect right.
My problem is that the element is not on the gameObject's perfect right, but sensibly above. See this schema:
Expectation:
G -> UI element
Reality:
---> UI element
G
I tried also to use the WorldToViewportPoint() but it's not giving the desired result.
So, I think this is the right way to go but I can't guess what I'm missing.
Any clue?
EDIT:
After a little bit more observations it seemed that the UI element alignment depends somehow on it's distance from the center of the screen (of the camera viewport I guess), so that if the gameObject is below half height the UI element y position won't be on the perfect right but slightly below it and if above half heigth will be slightly above the perfect right. Same for x coordinate. Is there a way I could control this?
