Legacy GM [Solved] Get an object's coordinates on the GUI layer

[A Random Creator]

I have a chest object in my game that shows what is in it when you click on it. The problem is that I want the inventory to be drawn on the GUI layer but still next to the chest. The issue is, I don't know how to find out where on the GUI layer the chest would be.
Any help is appreciated!

substract your views x/y from your chest objects x/y
the GUI layers x/y starts with 0,0 where your views x/y is

I use this methode in my own game to show object "popup" name tags on the GUI layer when you mouse-over objects on the regular layer (application_surface)

This doesn't seem to work for me,
I created two scripts (just to make it easier for me to do)
XtoGUI:

///XtoGUI(x)
return(argument0-view_xview)

YtoGUI:

///YtoGUI(y)
return(argument0-view_yview)

and I created this in the draw event to test it:

draw_text(XtoGUI(x),YtoGUI(y),"Test")

but it isn't centered on the x and y. It seems to move slightly in the opposite direction as I move the view_xview and view_yview.

sorry I forgot to add that this works if your view_port and window aspect ratio are the same, if any of these two is different you need to calculate for this offset too

That's not really what the GUI draw event is for, but ok.

It actually depends on a lot of factors.
It depends on whatever you've used display_set_gui_maximise,
on whatever you're using views, how many views there are (with multiple views, there might be multiple results or none at all),
on the x and y of the views, the width and height of the views, the x and y of the ports, the width and height of the ports,
window dimensions, fullscreen, ...

Generally speaking though, you should be able to just do this:

///XtoGUI(x)

var t = application_get_position();
return (argument0 - view_xview) / view_wview * (t[2] - t[0]);

ok this works, thanks!
