[C++] Checking current coordinates



Dear community,


for a quest I'm currently writing I need a new quest event which is thrown if the character is around a special position. The position can be fixed but the thing is that I don't know how to solve this without a even function (C++) which is checking the current position every second. I don't think that this is good for performance so is there any other possibillity? How is it done at portals, for example?

int get_x() { return CQuestManager::instance().GetCurrentCharacterPtr()->GetX(); }
int get_y() { return CQuestManager::instance().GetCurrentCharacterPtr()->Get>(); }

For the timer you can look how it's defined at the timer functions in the questlua codes.

I search for an other way. The way with the timer is, of course, a way to the solution but it's a bad one and I search for a better solution which is not as that performance-heavy.

I will give a try but I thought this would be very performance-heavy if I check every second for ~500 players the coordinates (one time get them and check them to 8 other coordinates and use a DISTAMCE_APPROX for this). But okay. I will give a try :)
