Ошибка "TypeError: свойство" SMTH 'Object' SMTH 'не является функцией " ⇐ C++

[Anonymous]

I'm following a tutorial for a game on QML (link:https://www.youtube.com/watch?v=0Nbt2yO ... annel=KALI)
I'm pretty sure that I have the exact same code, so why Ошибка появляется?

Когда я нажимаю a или d , он написал либо

typeerror: свойство 'Moveright' Controler (0x7f601ff8c0) не является функцией. /> или < /p>

Я был бы очень благодарен, если вы исправили мой код.>
