Multiply

Standard multiplication. UE 5.5+ defaults to Multiply_Double; older code may use Multiply_Float — both work in Blueprints.

Float

A real number with decimals. UE 5.0+ uses double-precision by default. Use for distances, percentages, time.

Double jump system with jump counter for character

Pattern: Variables JumpCount(int)=0, MaxJumps(int)=2. Jump input → Branch(JumpCount < MaxJumps) → True: LaunchCharacter(0,0,JumpZVelocity) → SET JumpCount+1. OnLanded event → SET JumpCount=0. Don't use built-in Jump for multi-jump — use LaunchCharacter instead.

Multiply_FloatFloat — multiply two floats

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

Add_FloatFloat — add two floats

Pin names A, B, ReturnValue.

Less (float) — A < B

Multiply_FloatFloat — multiply two floats (KismetMathLibrary)

Equal (float) — check if two floats are equal

Pure node. Use ErrorTolerance (default 0.0001) for floating-point comparison.

Max float — return larger of two floats

NearlyEqual float — check if two floats are approximately equal
