[Feature Request]: Provide an option to always draw debug geometry on top of everything else

[visuallization]

Feature description

Hey there!

First of all, thanks for the great plugin. Having convenient debug drawing capabilities in godot with your plugin really makes life easier.

I have a question/feature request: Is it possible to draw the debug geometry always on top of everything else. So e.g. if I would draw a line visuallizing a raycast, would it be possible to still see the line once it enters a mesh? I would also find this convenient e.g. when I am calculating some positions in a mesh and want to make sure I actually calculated the position correctly by displaying them with debug draws. Hope this makes sense.

Maybe this is already possible, but if not it would be great to have this option as well.

Cheers,
Florentin

Solution approach

Provide an option to always draw debug geometry on top of everything else.

Do you mean to draw all the geometry on top of everything else? Or only certain draw_* calls, for example with the no_depth_test=true flag?

If the first option, then it's not difficult to add (just change the material parameter), but if the second one, then I can use the idea from #3, like:

DebugDraw.set_depth_test(false)
DebugDraw.draw_box(...) # draw box on top of everything else
DebugDraw.set_depth_test(true)
DebugDraw.draw_sphere(...) # normal draw

And somewhere on _init()

DebugDraw.default_depth_test = true

or expose it in ProjectSettings.

And I suppose this is necessary for Godot 3 and 4?

Hey there,
Thanks for the reply!
Yes I was rather think about the second solution and support for Godot 3 + 4 would be really cool!

Regarding your proposed first solution, I think I still might be missing something. Can you assign a material to a debug draw call? Or do you mean I should set no_dept_test on the object I want to draw on, because if I do that, it does not seem to work.

Cheers

The screenshot was just for reference to the No depth test flag.
Now there is no way to change this parameter of the material through the DebugDraw API.

First I want to port what already worked in Godot 3, then I will add something new.

But for now, you can manually change this parameter of the materials (only in godot 3)

This would be really helpful to be able to do in godot 4. Sometimes my points get hidden behind my objects and it'd be helpful to have them always appear on top.

I would also like this feature.

This would be great!

Since my gizmo is drawn with separate lines and arrows, disabling the depth test leads to incorrect sorting of objects.

But using wireframes it is not noticeable :)
