Lekce 22 - Unity (C#) Android: Návrat do menu

V minulé lekci, Unity (C#) Android: Vylepšení plivání ohně, jsem se zabýval změnou ovládání pro plivání ohně.

Dnešní tutoriál se bude na vyžádání jednoho z diváků zabývat vytvořením tlačítek na začátku hry, aby měl po spuštění hry hráč možnost návratu do menu.

Nový PlayerMoveScript

Problémy?

Pokud máte nějaké otázky, neváhejte se zeptat v komentářích nebo mi napsat do zpráv.

V příští lekci, Unity (C#) Android: Konec hry, si ukážeme, jak hru nahrát na Google Play.
