I’m new to GDNative c++, i have a problem when calling Input::is_action_pressed(“ui_right”) :

void Player::_physics_process(float delta) {

bool right = Input::is_action_pressed("ui_right");
 bool jump = Input::is_action_pressed("ui_up");

    if (right)
        motion.x = SPEED;
    else if (left)
        motion.x = -SPEED;
    else
        motion.x = 0;
}

I get this error code :

    scons: Reading SConscript files ...
scons: done reading SConscript files.
