Yes that was what I need for my game. Thank you very much

It is good to put this in manual online because there is nothing where you can find how to make panel to be in full screen like this with all parts to be visible. Why is this so hard with game studio to have I dont know. It is basic for all games.

What do you want to do with this statement: panel.scale_x = screen_size.x/1920;?
For example, if you want a fullscreen panel i think this will be enough:
panel.size_x = screen_size.x;
panel.size_y = screen_size.y;

Do not forget to set this
panel.x=0;
panel.y=0;

Hope this help.

No it is not good to do it like this with no bmap numbers.

My code:
panel.scale_x=(screen_size.x)/1920;
panel.scale_y=(screen_size.y)/1080;

Because my bmap is 1920/1080 and it is good but I failed because I put it before level_load. After level_load everything is work.

Thank you in any way for help.

it's nothing to do with level_load,

screen_size isn't set until after the initial wait(1), so any maths with it will obviously fail
