ACharacter::LaunchCharacter

function Engine Blueprint Since 4.0

#include "GameFramework/Character.h"

Access: public

Description

Applies a velocity impulse to the character, overriding or adding to the current velocity. Used for knockback, explosive force, launch pads, and similar effects.

Signature

void LaunchCharacter(FVector LaunchVelocity, bool bXYOverride, bool bZOverride)

Parameters

Name	Type	Description	Default
LaunchVelocity	FVector	The velocity to apply to the character.	—
bXYOverride	bool	If true, replaces XY velocity. If false, adds to existing XY velocity.	—
bZOverride	bool	If true, replaces Z velocity. If false, adds to existing Z velocity.	—

Return Type

void

Caveats & Gotchas

• This should be called on the server in multiplayer. The resulting velocity is replicated.
• Setting bXYOverride and bZOverride to true effectively teleports the velocity to exactly LaunchVelocity.

Example

Launching the character upward C++

// Launch the character straight up at 1500 units/sec, preserving XY
MyCharacter->LaunchCharacter(FVector(0.f, 0.f, 1500.f), false, true);

// Full knockback: override all axes
MyCharacter->LaunchCharacter(KnockbackVelocity, true, true);
