Title: Client function ScreenPosToWorld
Post by: ℛḝξ☂ on Aug 24, 2021, 01:14 AM
GUI::ScreenPosToWorld(Vector screenPosition)

I wonder how this function works, and why the parameter screen position is Vector instead of VectorScreen, any help is appreciated!

This function is used to convert the world's 3D co-ordinates to the client's 2D screen co-ordinates.

Its the other way around. The Z parameter in Screen -> World Pos or World Pos -> Screen represents visibility. Value is between -1 or 0 (forgot exactly) if the vector is not visible on screen and anything else if it is. (You probably have to test)

My bad, didn't read the function name closely. If the Z coordinate is in negative, the vector is formed behind the player's screen (from my last experiment)

I am using this function to enable players to mark a certain place with a sprite. Your information helps and this work is done! Btw if I change the value of Z parameter in Screen position to 0 or -1 I cannot see the mark/sprite, I try to use 1 and it works.
