What is the fundamental difference between render overlay event and status bar class?
Because, after looking in status bar class, I have a feeling that it just a over complicated render overlay event. Because it mostly use screen struct and texture manager for drawing stuff.
Plus, for me, logic of render overlay is more....more easy and understandable than status bar. Just two line, check for texture and for player, and I can draw amount of health. Or armor protecting value.
So, if I use render overlay to draw on a screen amount of health, ammo, keys and etc., instead of status bar, my PC dont explode and/or at me, from a dark corner of a room, dont jump someone from the developers of the gzdoom and wildly rolling his eyes cry "USE STATUS BAR CLASS FOR THIS!!!!!111"?
Or I did not notice something important when look through status bar class?

Re: Difference between render overlay and status bar class
The status bar is so complicated because it needs to automatically handle user's scale and HUD mode settings.
As a result, the status bar comes with its own set of draw functions that can align the content to the edges of the screen or the center and put the contents of your status bar into a predefined rectangle of arbitrary size, where the user would expect it.
f you try to use the overlay you got to have to do all of this by yourself - and if you don't, your users will complain because your mod doesn't properly handle their preferred settings.
Ultimately, yes, the status bar is just an overlay, but with a large number of convenience functions added to it and a lot of implicit semantics to make it easier to create a HUD that automatically adjusts to user settings.
