Ue4 tick as timer6/17/2023 ![]() So it really depends on what you trying to do. Active timers will continue to execute indefinitely at the frequency determined by their execution period until unregistered. Executing code every 2nd or 3rd tick is also viable option but it’s frame dependent. An active timer is a delegate function explicitly registered by a widget that causes a Slate tick/paint pass upon execution, even in the absence of user action (thus the 'active' nature of the timer). ![]() But keep in mind that timer depends on ticking to, there no sense of time in CPU, the way timer works that on each frame (same as tick is called), timer system checks if time has passed, if yes call binded function/event, so with using a little bit higher time and you care about precision function might be called in irregular way, using timer on small time is kind of iffy. Despite its name, TickTimer is not really a timer, but rather a struct which stores a target tick value and run checks using the current simulation tick. An actor or component's tick group is used to determine when in the frame it should tick, relative to other in-engine frame processes, mainly physics simulation. While this method is a viable method for creating an Editor Tick, there is currently no way to disable it and every reconstruct starts a new tick timer. ![]() Ticking happens according to tick groups, which can be assigned in code or Blueprints. While Unreal Engine does not have a native Editor Tick inside the engine, we can create one using blueprints. There no difference between timer or tick if time is smaller then frame rendering time, so if you gonna do 0.01 which is 10ms it will execute in same rate as tick and take same amount of performance on 60fps, you need to do it higher time or else it does not make much sense. Actors and components are ticked once per frame, unless a minimum ticking interval is specified. Besides, the whole dOn’T uSE TiCk argument is really better stated as, Don’t run code more often than you need to. Tick is great for this sort of quick, lightweight stuff. Every Tick, or frame, we are adding some rotation to the pitch of the. As others have already said, you shouldn’t try avoiding Tick for this kind of thing. That why doing heavy operations on tick in blueprint is not recommended and you should move that in C++, but even there you need to watch out and don’t do things like actor iteration (same things that “Get All Actors of Class” does) Prerequisites: Basic knowledge of the UE4 editor, basic blueprint skills. I think what this video was stateing is Using tick in blueprint is not efficient because blueprint VM is around 10 slower then native code in C++, and you only have 16ms to update game state for next frame in case of 60fps and all ticks needs to be fully executed to finish the frame, the more fps the time is even smaller.
