Unable to change the font for rendering text.

[MetalDeveloper]

Hello,

Recently while making something I came across something were I wanted to change the font, in the process I have came up with an idea of how to do it but for some reason it will not change the font and stays the default font. I don't know if this is an issue on my end or the program itself. I am trying to render text onto the screen. Here is my code to do so.

void DrawOverlay() {

 var font = ImGui.GetIO().Fonts.AddFontFromFileTTF(@"C:\Windows\Fonts\Roboto-Regular.ttf", 999);
 ImGui.PushFont(font);
 ImGui.PopFont();

 Vector2 screenSize = new Vector2(ImGui.GetIO().DisplaySize.X, ImGui.GetIO().DisplaySize.Y);

 if (drawWatermark)

{ ImGui.SetNextWindowSize(screenSize); ImGui.SetNextWindowPos(new Vector2(0, 0)); ImGui.Begin("Overlay", ImGuiWindowFlags.NoDecoration | ImGuiWindowFlags.NoBackground | ImGuiWindowFlags.NoBringToFrontOnFocus | ImGuiWindowFlags.NoMove | ImGuiWindowFlags.NoInputs | ImGuiWindowFlags.NoCollapse | ImGuiWindowFlags.NoScrollbar | ImGuiWindowFlags.NoScrollWithMouse );

     ImDrawListPtr drawList = ImGui.GetWindowDrawList();

     drawList.AddRectFilled(new Vector2(2, 5), new Vector2(120, 30), ImGui.ColorConvertFloat4ToU32(new Vector4(0.08f, 0.08f, 0.085f, 1f)), 10f);
     drawList.AddText(font, 23f, watermarkPos, ImGui.ColorConvertFloat4ToU32(new Vector4(1f, 1f, 1f, 1f)), "ExampleText");

 }

}

Please help me fix this if I am doing something wrong on my end. Also yes, the custom ttf file is in the correct directory.

Font changing isn’t easy in this lib, sometime code is better than 1000 words so use this as reference: https://github.com/zaafar/ClickableTransparentOverlay/blob/master/Examples/SingleThreadedOverlayWithCoroutines/SampleOverlay.cs#L116

I tried that but I get this error when I run it.

Here is my code (My goal is to make a watermark that is displayed on the screen):

if (drawWatermark) { ImGui.SetNextWindowSize(screenSize); ImGui.SetNextWindowPos(new Vector2(0, 0)); ImGui.Begin("Overlay", ImGuiWindowFlags.NoDecoration | ImGuiWindowFlags.NoBackground | ImGuiWindowFlags.NoBringToFrontOnFocus | ImGuiWindowFlags.NoMove | ImGuiWindowFlags.NoInputs | ImGuiWindowFlags.NoCollapse | ImGuiWindowFlags.NoScrollbar | ImGuiWindowFlags.NoScrollWithMouse );

   ImDrawListPtr drawList = ImGui.GetWindowDrawList();

   if ((DateTime.Now - _lastTime).TotalSeconds >= 2.25)
   {
       // one second has elapsed 

       _fps = _framesRendered;
       _framesRendered = 0;
       _lastTime = DateTime.Now;
   }

   this.ReplaceFont(@"C:\Windows\Fonts\msyh.ttc", 23, FontGlyphRangeType.English);
   font2 = null;

   //drawList.AddRectFilled(new Vector2(2, 5), new Vector2(120, 45), ImGui.ColorConvertFloat4ToU32(new Vector4(0.08f, 0.08f, 0.085f, 1f)), 6f);
   drawList.AddText(watermarkPos, ImGui.ColorConvertFloat4ToU32(new Vector4(1f, 1f, 1f, 1f)), "MetalWare");
   drawList.AddText(fpsPos, ImGui.ColorConvertFloat4ToU32(new Vector4(1f, 1f, 1f, 1f)), "FPS: " + _fps);

   if (font2 != null)
   {
       ImGui.PushFont(font2.Value);
   }

Make sure you are using the latest version of imgui.net. We fixed this bug few months ago.

[MetalDeveloper]

I was using an outdated version, im testing it rn.

[MetalDeveloper]

i get this error when i updated to the latest release (im using .net 6.0)

[MetalDeveloper]

Only works for me without crashing

[zaafar]

You don’t need vsync feature of that library, just remove that if condition.

[MetalDeveloper]

I removed that line and i get that (thats not my code thats the actual im gui .net code)

[MetalDeveloper]

i also get this with it

[MetalDeveloper]

Do you have a discord? Can I add you on their and you can help me easily?

[zaafar]

How can I reproduce this issue on my side? For this purpose, I am wondering if u can give me the changes required to reproduce the issue in the sample projects (e.g. https://github.com/ImGuiNET/ImGui.NET/tree/master/src/ImGui.NET.SampleProgram OR https://github.com/zaafar/ClickableTransparentOverlay/tree/master/Examples)

[MetalDeveloper]

Can I just send you a simple project that does the same thing?

[MetalDeveloper]

Can I add you on discord so you can help me easier?

[MetalDeveloper]

my discord is: metal_developer

[MetalDeveloper]

💀 you helped me then just said good luck when it created a problem

[MetalDeveloper]

i fixed it

[zaafar]

I knew you would be able to fix it yourself, good stuff! Closing the issue.

[hoootis]
