Clamp (float) — clamp float value between Min and Max

Clamp

Bounds a value between Min and Max. Useful for clamping health to [0, MaxHealth] etc.

FClamp — clamp float value between Min and Max

FClamp for float, Clamp for int.

Health system: take damage, clamp health, check death

Pattern: EventAnyDamage → Subtract_FloatFloat(A=CurrentHealth, B=Damage) → Clamp(Value=Result, Min=0, Max=MaxHealth) → SetVariable(Health=ClampResult) → Branch(Condition=(Health <= 0)) → True: call OnDeath custom event. Variables needed: Health (float), MaxHealth (float). EventAnyDamage output pin is 'Damage' (float). Clamp inputs: 'Value', 'Min', 'Max'. All floats.

MapRangeClamped — remap value from one range to another, clamped

Output clamped to OutRange. Use MapRangeUnclamped for unclamped version.

AddForce — apply continuous force to physics body

Continuous force — apply every frame. Use AddImpulse for one-shot.

Pressure plate trigger that activates when enough weight is on it

Pattern: BoxCollision trigger, variable OverlappingActors(int)=0. OnBeginOverlap: OverlappingActors++ → Branch(OverlappingActors >= RequiredCount) → Activate. OnEndOverlap: OverlappingActors-- → Branch(OverlappingActors < RequiredCount) → Deactivate. Use interface or event dispatcher to notify connected actors (doors, platforms).

Button

A clickable UMG widget. Hook OnClicked in the Graph to handle the press.

Gate — open/close/toggle flow gate

Macro. Enter only passes through when gate is open.
