Waxaa la block and in the loop: they're iyo . In the first fragment, we first initialize Waxaa la Block, iyo ka dib markii ay ku habboonayaa in a Haku different try for num i startIndex try for Therefore, in the second fragment, two different variables are compared in an identical check: iyo Markaas ka mid ah wax soo saarka ah waa in ay ka mid ah mid ka mid ah mid ah mid ka mid ah mid ka mid ah mid ah mid ka mid ah mid ah mid ka mid ah mid ah mid ka mid ah mid ah mid ka mid ah mid ah mid ah mid ka mid ah mid ah mid ka mid ah mid ah mid ka mid ah mid ah mid ka mid ah mid ah mid ka mid ah mid ah mid ka mid ah mid ah mid ah mid ka mid ah. . num i startIndex == startIndex Sidaa waxaa laga yaabaa in la soo xiriir ka mid ah dalalka ugu horeysay ee loo yaabaa. ?

Haku: Haku Waxaa laga yaabaa in la warqad iyo waa zero, iyo ka dib markii ay soo bandhigay si toos ah. Tani is problem crystal clear. Let's look at the consequences of the error. first startIndex for Waayo, waxaan u baahan tahay in ay ku saabsan script-in-game oo loo soo saarka bonuses for "Strength". Waayo, ka dibna soo saarka 2 bonussada oo ka mid ah 1 iyo ka dibna soo saarka 5 iyo 15, soo saarka: This is what in-game scripts look like. We created bonuses for "Strength" with indices 0 and 1, and then assigned them the values. Tani, in theory, haddii aad u soo bandhigi karaa mid ka mid ka mid ah "Strength", waxaan ka heli karaa 5 iyo 15?
