With this code I wanted to visually delineate the complete view of the circuit and the two cars checked:
draw_rectangle(0,0,1279,719,true); draw_rectangle(0,720,639,1079,true); draw_rectangle(640,720,1279,1079,true);
It turns out that only the complete view of the circuit drawn directly into the room is correctly delimited (observe the black line of a thick pixel):
Where there should be rectangle features (red line, not necessarily at this thickness):
This happens because of this camera / window:
I believe that the rectangle is drawn under the camera / viewport.
What should I do for this rectangle to be drawn on the camera / window?
