Lekce 23 - Unity (C#) Android: Konec hry

V minulé lekci, Unity (C#) Android: Návrat do menu, jsem se zabýval možností kdy se může hráč ještě před začátkem hry vrátit do menu.

Dnešní tutoriál už naplní mnou dlouho dávaný slib, kdy jsem říkal, že udělám konec hry. Zároveň mi přišlo jako dobrý nápad vytvořit tlačítko, které je volně škálovatelné, tedy bez deformace nebo ztráty kvality.

Jak hra vypadá nyní?

Problémy?

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

V příští lekci, Unity (C#) Android: Publikování na Google Play, se mrkneme na proces publikování hry na Google play.
