UCharacterMovementComponent::SetWalkableFloorZ

function Engine Blueprint Since 4.0

#include "GameFramework/CharacterMovementComponent.h"

Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Sets the minimum Z component of a walkable surface's normal, and recomputes WalkableFloorAngle to match.

Caveats & Gotchas

• Clamped to [0, 1]; a value of 1 means only perfectly flat floors are walkable, while 0 allows slopes all the way up to vertical.
• Overwrites WalkableFloorAngle as a side effect, computed as acos(Z) in degrees — don't call SetWalkableFloorAngle() afterward expecting both to persist independently.

Signature

void SetWalkableFloorZ(float InWalkableFloorZ)

Parameters

Name	Type	Description	Default
InWalkableFloorZ	float	New minimum walkable-surface normal Z component; clamped to [0, 1].	—

Return Type

void

Example

Set the walkable limit using the Z normal directly C++

void AMyCharacter::BeginPlay()
{
	Super::BeginPlay();
	// Roughly equivalent to a 45 degree slope limit.
	GetCharacterMovement()->SetWalkableFloorZ(0.707f);
}
