Smooth float variable change using FInterpTo on EventTick

Pattern: EventTick → FInterpTo(Current=CurrentValue, Target=TargetValue, DeltaTime=DeltaSeconds, InterpSpeed=5.0) → SetVariable(CurrentValue=InterpResult) → [use CurrentValue for UI or material or rotation]. Key: FInterpTo inputs: 'Current' (current float), 'Target' (goal float), 'DeltaTime' (from Tick's 'DeltaSeconds' output), 'InterpSpeed' (how fast, try 3-10). The result approaches Target exponentially — it never exactly reaches Target (use Branch + Clamp if needed).

NearlyEqual float — check if two floats are approximately equal

Max float — return larger of two floats

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

Add_FloatFloat — add two floats

Pin names A, B, ReturnValue.

Less (float) — A < B

Multiply_FloatFloat — multiply two floats

Pin names A and B. C++ name stays Multiply_FloatFloat even in UE 5.7.

Divide_FloatFloat — divide A by B

RandomFloatInRange — random float between min and max

RandomFloatInRange — random float between Min and Max
