Getting mouse room coordinates

[Goot]

Is there a way to get the mouse room coordinates in a scrolling screen? At one point I remember seeing variables for how much the screen is scrolled, which you could add to mouse.x or mouse.y, but I can't seem to find them anywhere in the help section. Do scrolling variables exist, or is there another way to get mouse screen coordinates?

Search for viewport x and y values.

Yep, mouse.x/y are always relative to the current viewport position.

To get the room coordinates do as Moebius 5.18 said:

int roomX = GetViewportX() + mouse.x;
int roomY = GetViewportY() + mouse.y;

I am doing a scrolling background screen

I will be using a gui which is the size of the regular screen size so that when scrolling the screen the gui stays in place

I am trying to figure out how to implement something simular to whats shown in this example in the post

I need to be moving the mouse around on screen and have the coordinates for the scrolling screen display in my gui.

I need to know step by step instructions of how to do this
