Paint a texture.

[Santiago]

Hello, I have the following dilemma.

I found that making a menu using a shot in front of the camera, and drawing the menu in a texture buffer is very efficient.

The problem I have is that I don't know how to convert my Mousex () & mousey () position to the strings inside the texture.

It would be as if I wanted to paint a texture with the cursor, I remember seeing examples, but I can't find any, would they help me with that?


my menu method works like this. but i use a local mousex and mousey to draw a cursor inside the texture, but i need to use the real mouse screen.
