[C++] Npc prodávající levely za tokeny

 

Co bych to dlouze popisoval, chtěl jsem trochu flexnout na acwebu, tak jsem splácal tohle.

Je to npc, co vám prodá level výměnou za token. Množství levelů hráč vepisuje do codeboxu (je mu zděleno i maxmální číslo jaké může zadat).

Cena se pak vypočítává za každý level který npc udělí, s tím že se cena každý level násobí nastavenou hodnotou.

 

Potřebujete vědět jak přidat script do scriptloaderu, kompilovat, blablabla. Však to znáte.

Stačí npcflag 1, scriptname npc_level_vendor.
