Development Programming & Scripting

I am trying to detect touch input using hitboxs but not able to make them work.

.h

virtual void ReceiveHitBoxClick(const FName BoxName) OVERRIDE;

.cpp

        void AMyProjectHUD::DrawHUD()
        {
        	Super::DrawHUD();
        
        .....
        .....
        .....
        
    VDrawTile(FireTex, ((Center.X - (128 * 0.5)) + (Center.X*0.75)),
    		((Center.Y - (128 * 0.5f)) - (Center.Y*0.12)), EFireIconSize, EFireIconSize, FColor(255, 255, 255, 255));
    
    	FVector2D HBPos = FVector2D(((Center.X - (128 * 0.5)) + (Center.X*0.75)),
    		((Center.Y - (128 * 0.5f)) - (Center.Y*0.12)));
    
    	FVector2D HBSize = FVector2D(EFireIconSize, EFireIconSize);
    }

VDrawTile is an inline function that calls DrawTile.

No click is tested when i test it in the mobile preview in ue4.
