ACharacter::CheckJumpInput

function Engine Since 4.0

#include "GameFramework/Character.h"

Access: public Specifiers: virtualENGINE_API

Description

Called each frame by CharacterMovementComponent to process jump input. Consumes bPressedJump, increments JumpCurrentCount, and calls OnJumped() when a new jump is initiated.

Caveats & Gotchas

• This function increments JumpCurrentCount and sets JumpCurrentCountPreJump. Overrides that do not call Super::CheckJumpInput() must manage these variables manually, or multi-jump and network prediction logic will silently break.
• CheckJumpInput is called from the movement component, not from the character's own Tick. Do not call it directly — set bPressedJump to true and let the movement component invoke it on the correct tick.

Example

Add a stamina gate to jumping by overriding CheckJumpInput C++

void AMyCharacter::CheckJumpInput(float DeltaTime)
{
    if (bPressedJump && Stamina < JumpStaminaCost)
    {
        // Not enough stamina — cancel the jump request
        bPressedJump = false;
    }
    Super::CheckJumpInput(DeltaTime);
}
