Solved How do I update floating text?

I have this code:

PHP:

    public function onInteract(PlayerInteractEvent $event){
        $player = $event->getPlayer();
        $block = $event->getBlock();
        $level = $this->getServer()->getDefaultLevel();
        if($block->getId() == 46) {
            if($this->mode>=0&&$this->mode<=1000) {
                $this->mode++;
                $this->text = new FloatingTextParticle(new Vector3(77, 48, -892), "");
                $this->text->setText("§bYour score: §6" . $this->mode . "");
                $level->addParticle($this->text);
            }
        }
    }
}

The problem with this is that the floating text dose not update.. it just spawns another floating text. how can I just make it update the text?

 

solved it myself before a reply. there's no point deleting this, I'll leave it here in case anyone has this problem in the future. fix:
onEnable:

PHP:

$this->text = new FloatingTextParticle(new Vector3(77, 48, -892), "", "");

onInteract:

PHP:

    public function onInteract(PlayerInteractEvent $event){
        $player = $event->getPlayer();
        $block = $event->getBlock();
        $level = $this->getServer()->getDefaultLevel();
        if($block->getId() == 46) {
            if($this->mode>=0&&$this->mode<=1000) {
                $this->mode++;
                $this->text->setText("§bYour score: §6" . $this->mode . "");
                $level->addParticle($this->text);

            }
        }
    }
}
