I hope you found this post helpful to you. World->GetTimeManager().SetTimer(time_handler, this, &toggleVisibility, period) You can turn this off to improve performance if you don't need it. Set this actor to call Tick() every frame. ![]() Virtual void Tick( float DeltaSeconds ) override Called when the game starts or when spawned Sets default values for this actor's properties Here is an example of using the Event Tick to toggle the visibility of a blueprint actor every 2 seconds: The in-between frame duration is GPU bound so on some PCs, the timing looks correct, but completely off on others. The timing will be a bit off because the in-between frame duration may not sum up to your specified time without going over by one tick. Game tick is simple to use, but it does have its downsides. You can easily take advantage of this functionality by summing up the duration between frames until you reach a specific time. This event happens every frame and the parameter the event get is the duration between the last frame tick. Game tick is associated with the Event Tick Blueprint node or “Tick(float)” function in C++. public: // Called every frame virtual void Tick(float DeltaTime) override void RepeatingFunction(). This can result in unwanted visuals that can cause simulation sickness. ![]() You call the function or Blueprint node and then within the same scope of where the function was called pauses for a specified duration then resume.Īlthough the delay function is simple to use, it is also dangerous because the stall can affect other parts of your project. In this post, my goal is to share with you which one I found to work the best for time critical events.ĭelay is the simplest form of time management. I have experience working with each of them in VR development, so I thought I would share what I have learned. The reason for this is that there are three main ways (delay, game tick, and timer) to handle time in Unreal Engine 4 (UE4). VR is resource heavy and may affect the time driven events you are developing in your project. This is a very watered down version of the Unreal tutorial s. One of the most challenging aspects of virtual reality (VR) development is meeting the spec requirements with our current level of hardware. We create a widget, and user blueprints on the game mode to create a timer.
