For problem #2, I guess I will just create a property for my HUD, then let the DoLabel() take in that property as argument. My ResourceManager will change the property somewhere else.

Text will be draw because of a given make sure to model your gui independetly from your model, in that case if the model changes state the gui will be able to reflect that with different text. (I hope this makes sense to you).

For the problem with buttons, try moving _imgui.Begin(); and End() outside of the for loop.

I have to say I was really exciting when I see this post. I was working on a structure for GUI for my game, and if I hadn’t found this, I would have stucked with many classes for buttons, image, etc…

While I’m trying this type of GUI, i have some difficulties:

1. I think this is mostly suited for interactive controls such as buttons, scrollbars, sliders, etc. For static controls like label, image, I don’t know how useful it is except drawing a texture or a string.

2. When creating a label, the text of the label will be updated by some other object. since IMGUI does not really create a Label object, how would you change the text when DoLabel on some update condition?

3. In my HUD I have a section for buttons consisting of 9 slots, putting in an array Buttons = Texture2D[9]. Normally, I would do:


for (int i=0; i<Buttons.Length; i++) {
var tex = Buttons[i];
if (tex == null) continue;

_imgui.End();
}


However, only slot 0 works; that is, only when I click on button 0, the event happens. Do you have any idea why?

Sorry for the long list of questions! I’m hoping you can find some timea in your busy schedule to answer them. Thanks.

And

return rectangle.Contains(new Point(mouse.X, mouse.Y)


The second one slipped in because at first I did some extra checks, but the first one is unexcusable, thanks for pointing these two out! I’ll fix them immediately.

or

return mouse.LeftButton == ButtonState.Released &&
hotItem == id
&& activeItem == id;


Basicly, what you are saying is:


if(something == true)
return true;
else if(something == false)
return false;

That doesnt look right IMHO.
