UKismetMathLibrary::Vector2DInterpTo_Constant

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Moves a 2D position toward a target at a constant speed per second, clamping at the target when reached. Unlike Vector2DInterpTo, this does not slow down as it approaches.

Caveats & Gotchas

• InterpSpeed here is a linear units-per-second rate, not the exponential 'feel' factor used by Vector2DInterpTo. Switching between the two requires recalibrating the speed value.
• The result is clamped to the target when the remaining distance would be exceeded by the current step, so it will never overshoot.

Signature

static UE_INL_API FVector2D Vector2DInterpTo_Constant(FVector2D Current, FVector2D Target, float DeltaTime, float InterpSpeed);

Parameters

Name	Type	Description	Default
Current	FVector2D	Current position.	—
Target	FVector2D	Target position to move toward.	—
DeltaTime	float	Time elapsed since the last frame.	—
InterpSpeed	float	Constant movement speed in units per second.	—

Return Type

FVector2D

Example

Move a health bar to a new value at a fixed speed C++

// Move health bar fill position 50 units per second
HealthBarFill = UKismetMathLibrary::Vector2DInterpTo_Constant(
    HealthBarFill,
    TargetFill,
    DeltaTime,
    50.f
);
