laurencei / UE-BYGImguiLogger

Shows Unreal Engine logs in-game using ImGui

BYG Imgui Logger

Displays Unreal's UE_LOG output in an ImGui window.

Heavily based on the Console example from imgui_demo.cpp included with ImGui.

Features:

• Filter by verbosity: Error, Warning, Display etc.
• Filter by log category: LogTemp, Warning, Display etc.

Usage

You will need to draw the logger once every tick. You can try putting it in a APlayerController subclass and calling it there. Something like this:

if (ImGui::BeginMainMenuBar())
{
	if (ImGui::BeginMenu("Window"))
	{
		if (ImGui::MenuItem("Log"))
		{
			bShowLogWindow = !bShowLogWindow;
		}
		ImGui::EndMenu();
	}
	ImGui::EndMainMenuBar();
}

if (bShowLogWindow)
{
	UBYGImguiLoggerSubsystem* Logger = GetGameInstance()->GetSubsystem<UBYGImguiLoggerSubsystem>();
	Logger->Draw(&bShowLogWindow);
}
