Unity is building their new GC from it iirc. At least they have it on their github.

Hi guys, anyone here that can help with ImGuiNET implementation in Silk.NET?
I am trying to load a custom font but it straight up crashes the minimal example that is provided:

OnLoad():
_fontAwesome = ImGuiNET.ImGui.GetIO().Fonts.AddFontFromFileTTF(Path.Combine(assemblyPath, @"fa-solid-900.ttf"), 16);
.
.
.
OnRender():
ImGuiNET.ImGui.PushFont(_fontAwesome); // <- crashes
ImGuiNET.ImGui.Text("\uf007 User");

OnLoad():
_fontAwesome = ImGuiNET.ImGui.GetIO().Fonts.AddFontFromFileTTF(Path.Combine(assemblyPath, @"fa-solid-900.ttf"), 16);
.
.
.
OnRender():
ImGuiNET.ImGui.PushFont(_fontAwesome); // <- crashes
ImGuiNET.ImGui.Text("\uf007 User");

OnLoad():
_fontAwesome = ImGuiNET.ImGui.GetIO().Fonts.AddFontFromFileTTF(Path.Combine(assemblyPath, @"fa-solid-900.ttf"), 16);
.
.
.
OnRender():
ImGuiNET.ImGui.PushFont(_fontAwesome); // <- crashes
ImGuiNET.ImGui.Text("\uf007 User");

OnLoad():
_fontAwesome = ImGuiNET.ImGui.GetIO().Fonts.AddFontFromFileTTF(Path.Combine(assemblyPath, @"fa-solid-900.ttf"), 16);
.
.
.
OnRender():
ImGuiNET.ImGui.PushFont(_fontAwesome); // <- crashes
ImGuiNET.ImGui.Text("\uf007 User");

This works fine on the regular version of ImGuiNET so I am assuming something is wrong on Silk.NET side

did you regenerate the font atlas?

Lyris the KitoriOP•10/26/22, 4:21 PM

also, specify font config on the constructor for ImGuiController

if I call

I tried to merge the two fonts before creating the controller but unfortunately ImGuiFontConfig does not provide any means to load a range of glyphs or merge fonts

however PushFont() should always work...

they are only used where necessary

while speed isnt (and cant be) the same as System.Numerics, its well fast enough for basically all cases

Catsillas•10/27/22, 3:21 AM

yeah i was mostly worried about the gl calls specifically but i saw those use system numerics types, was pretty happy, so annoying converting between different math libs for that stuff

you wont see a Vector2D<float> anywhere

Lyris the KitoriOP•10/27/22, 3:22 AM

(if you do, thats likely a bug/oversight)

Lyris the KitoriOP•10/27/22, 3:22 AM

anywhere where we can, we use System.Numerics

Silk.NET.Math is simply there to fill in what System.Numerics is missing
