I believe the old EnableScissor(...) work more correctly than current one.


As you can see, the first screenshot is from commit 08a68d3c2d0ecac060c2a341232ddb901aecd4dc the second one is from 6ed53c713c453c9398428154b993ef99b9145920. It looks the old one works for me.
Currently I have daul monitor setup, both of them are 1080P and DPI is 125%.

Besides, I believe at line 446, it should be

                io.AddKeyEvent(keyItr.Value, Raylib.IsKeyDown(keyItr.Key));

instead of current one. Current one will crash directly.

Running this wrapper on an M1 machine will result in no visible / cut off output.

This problem can be solved on M1's (.NET 6.0) commenting out:
EnableScissor and Rlgl.rlDisableScissorTest() in rlImGui.cs.

Hello,

First of all, thank you for the your great job. Your project has been very useful for me.

Now, going back to the matter, I have been testing your project and I found a weird behaviour of ImGui. When the window is place out side the screen on the left side, ImGui glitches. I have been checking your code but i dont find the issue. I have attached two videos showing the issue.

Any idea what it could be happening?

I am on macOS Sonoma 14.3.1 running on a M1 Max.

MacOS 11.6 .net core 6.0

Unhandled exception. System.MissingMethodException: Method not found: 'ImGuiNET.RangePtrAccessor`1<ImGuiNET.ImDrawListPtr> ImGuiNET.ImDrawDataPtr.get_CmdListsRange()

For me this line crashes because there is an 'index out of range exception'.

foreach (var keyItr in RaylibKeyMap)
    io.KeysData[(int)keyItr.Value].Down = (byte)(Raylib.IsKeyDown(keyItr.Key) ? 1 : 0);

I figured that this is offset value is needed. It worked for me fine, text input is OK.

foreach (var keyItr in RaylibKeyMap)
	io.KeysData[(int)(keyItr.Value - ImGuiKey.KeysData_OFFSET)].Down = (byte)(Raylib.IsKeyDown(keyItr.Key) ? 1 : 0);

I am using the nuget version

I've been trying to get custom fonts working using rlImGui-cs for about 4 hours now - something that would take 20 seconds using C++ and ImGui - and I just can't figure it out.

I have tried:

1. Just as in C++, getting the IoPtr and loading the font from a TTF file. This does nothing. The font does not get used.
2. Doing 1, but then calling ReloadFonts. This does nothing.
3. Doing 2, but then using PushFont. This causes a memory corruption error and crashes.
4. Doing 1 & 2 in the InstallFonts callback.

None of these work. Do you have an functioning example of loading a custom font?

I am on Linux, so I don't know if this is a raylib, this libary, or if I am doing something wrong

SetTraceLogLevel(TraceLogLevel.Error);
SetConfigFlags(ConfigFlags.ResizableWindow);
InitWindow(400, 300, "Window");
rlImGui.Setup(true);
while (!WindowShouldClose()) {
	BeginDrawing();
	ClearBackground(Color.Black);

	rlImGui.Begin();

	//
	bool open = true;
	ImGuiWindowFlags flags =
		ImGuiWindowFlags.NoDecoration |
		ImGuiWindowFlags.AlwaysAutoResize |
		ImGuiWindowFlags.NoSavedSettings |
		ImGuiWindowFlags.NoFocusOnAppearing |
		ImGuiWindowFlags.NoNav;
	ImGui.SetNextWindowPos(Vector2.One * 10f);
	flags |= ImGuiWindowFlags.NoMove;
	ImGui.Begin("test", ref open, flags);
	ImGui.Text("HERE");
	ImGui.End();
	//

	rlImGui.End();
	EndDrawing();
}

CloseWindow();

this doesn't load properly on github.
https://github.com/raylib-extras/rlImGui-cs/blob/main/rlImGui/IconsFontAwesome6.cs

This is the format I identified for loading and changing a font:

var fontPtr = ImGui.GetIO().Fonts.AddFontFromFileTTF(@"path/to/font.ttf", 48f);
rlImGui.ReloadFonts();
unsafe {
    ImGui.GetIO().NativePtr->FontDefault = fontPtr.NativePtr;
}

Based on the Dear Imgui Demo

However, rlImGui-cs doesn't have the property setter on ImGuiIOPtr

Is there a cleaner way or can we add this to the README?

Hi, I'm using the latest versions of everything from nuget, these are the dependencies:

  <ItemGroup>
    <PackageReference Include="ImGui.NET" Version="1.90.0.1" />
    <PackageReference Include="Raylib-cs" Version="5.0.0" />
    <PackageReference Include="rlImgui-cs" Version="2.0.0" />
  </ItemGroup>

When running the simple demo program from the repo, i get this error:

Unhandled exception. System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at ImGuiNET.RangeAccessor`1.get_Item(Int32 index)
   at rlImGui_cs.rlImGui.FrameEvents()
   at rlImGui_cs.rlImGui.Begin(Single dt)
   at Program.Main() in Program.cs:line 29

I changed the version of ImGuiNET to 1.89.9.3 which nuget states as minimum required version and everything works.

Thanks a lot!

Problem:
When using rlImGui and using Raylib.MaximizeWindow(); and Raylib.ToggleFullscreen(); there are some text missing in imgui.

Setup:

rlImGui.Setup();
public override void Draw()
    {
        rlImGui.Begin();
        ImGui.ShowDemoWindow();
        rlImGui.End();
    }

public override void Update()
    {
        if (Raylib.IsKeyPressed(KeyboardKey.KEY_F11))
        {
           Raylib.MaximizeWindow();
           Raylib.ToggleFullscreen();
        }
    }

Showcase:

Note:
This does not happen when only using Raylib.ToggleFullscreen(); so it's an issue related when using fullscreen in a window that is maximized.
