SetActorTickInterval — change how often Tick fires

TickInterval=0.0 means every frame. TickInterval=0.1 means 10 times per second. Great for AI or non-critical logic that doesn't need per-frame updates.

Timer: call a function repeatedly using SetTimerByFunctionName

Pattern: EventBeginPlay → SetTimerByFunctionName(Object=self, FunctionName='OnTimerFired', Time=1.0, bLooping=true). Create a separate custom event/function named 'OnTimerFired' — this is what the timer will call. SetTimerByFunctionName inputs: 'Object' (Object, use 'self'), 'FunctionName' (string), 'Time' (float, interval in seconds), 'bLooping' (bool). Output: 'ReturnValue' (TimerHandle).

RandomBool — return random true or false

Timer with Set Timer by Function Name for repeating actions

Pattern: BeginPlay → K2_SetTimer(Self, 'MyFunction', 2.0, true) → store TimerHandle. Stop: ClearAndInvalidateTimerByHandle(TimerHandle). Prefer SetTimerByEvent over FunctionName for type safety. Delay node is simpler for one-shot but only works in Event Graph.

SetTimerByFunctionName — call a function repeatedly on a timer

Timer

Schedules a function to run after a delay or on a repeating interval. Cleaner than Delay for repeating work.

Sound Cue

A graph that mixes and routes one or more Sound Waves — fades, randomizes, attenuates. Older but battle-tested.

RandomUnitVector — random direction unit vector

Attenuation

Distance-based volume falloff. A Sound Attenuation asset defines the curve and falloff radius.
