1.16.5 Mouse Listener Mod - Problem Getting Cursor Coordinates

[Ryia]

Hi! I am doing a mouse listener mod that will capture some mouse dynamics from mouse movements and clicks. This is my first experience with modding in minecraft

I am having a problem and it is being really dificult to find information online. I need to get the current cursor location in relation to the screen, and I am using the mousehelper.posx() and mousehelper.posy() for that. However, this is returning negative values sometimes, and when I try to normalize it in an [0,1] interval it surpasses the limits. Maybe I am not understanding correctly what positions mousehelper.posx() and mousehelper.posy() are returning.

My code to normalize the mouse coordinates:

double screenX = mouseHelper.xpos() / screenWidth;
double screenY = mouseHelper.ypos() / screenHeight;

I dont think mouseHelper is the best approach to get the cursor location. Can anyone help me with this?

I am using Minecraft 1.16.5
