Console commands & vars

Engine & Editor commands

• Object console commands list

Miscs Commands

• ShowDebug [Name], by default this will give details about the player pawn/character
• ToggleDisplay : disables all HUD
• show COLLISION : displays collisions, works in PIE

Rendering commands

• FreezeRendering, good to use with ToggleDebugCamera, allows you to see how culling works, with extra stuff like seeing the POV of different steps of rendering (press B)
• ToggleDebugCamera
• ProfileGPU panel, also named “GPU Visualizer”
• r.Streaming.PoolSize XXX

Making your commands/vars

• Details about Exec functions
• For static variables (int32, float, bool, FString) see FAutoConsoleVariableRef
• For commands see FAutoConsoleObject and the childs such as FAutoConsoleCommandWithWorld or FAutoConsoleCommand

Code snippet

#if !NO_CVARS && TFC_WITH_CONSOLE  
    /**  
     *     
     *  @return "TFC.Debug.TheName"     
     *  @return "TFC.Debug.OptionalSubCatepgry.TheName"
     */
#define TFC_Console_Internal_BuildFullCommandString(SubNameString, SubCategoryString) \  
    FString::Printf(TEXT("TFC.Debug.%s"), *(SubCategoryString.IsEmpty() ? SubNameString : SubCategoryString + "." + SubNameString))  
  
    struct FTFCAutoConsoleCommandWithWorld : private FAutoConsoleCommandWithWorld  
    {  
       FTFCAutoConsoleCommandWithWorld(const FString& SubName, const FString& Help, const FConsoleCommandWithWorldDelegate& Delegate, const FString& OptionalSubCategory = "")  
          : FAutoConsoleCommandWithWorld(*TFC_Console_Internal_BuildFullCommandString(SubName, OptionalSubCategory), *Help, Delegate, ECVF_Default)  
       {}  
    };
//...

Custom command declaration example

// example 1, works in constructor
IConsoleManager::Get().RegisterConsoleCommand(
	TEXT("TFC.Debug.DisplayInGamePlayerCharacterWindow"),  
	TEXT("Show data for player"),  
	FConsoleCommandDelegate::CreateWeakLambda(this, [this]()  
	{
		bDisplayDebugWindow = !bDisplayDebugWindow;
	})
);
 
// example 2 (Northstar)
auto& ConsoleManager = IConsoleManager::Get();
ConsoleManager.RegisterConsoleCommand(
	TEXT("CyGlass.ToggleOverlay"),
	TEXT("Toggle CyGlass overlay."),
	FConsoleCommandDelegate::CreateUObject(this, &UCyGlassExtensionSubsystem::ToggleCyGlassOverlay))
);

About re-registration warning (console commands and vars)

you might get the following warning Console object named 'xxx' already exists but is being registered again, but we weren't expected it to be! You can totally ignore it if it happens when you hot reload/live code. For more details read the comment above the UE_LOG line
