Multiple scripts may depend on this library so modifying it can break other scripts. - - Purpose: - For easy in-game designation of persistent polygonal zones which are used by any script. - - How to Use: - All zones are saved in zones.List; see an example below. - Zone creation is handled with weapon_zone_designator and ent_zone_point, but can be done in code as well. - When a zone is created, changed, or removed all zones are synced to clients. When clients join they are also synced. - Any extra details can be saved to a zone. Everything is written to a txt file and is persistent to the map. - - Since multiple scripts might use the zones system, don't assume that every zone is related to your script. - To register a zone class, use zones.RegisterClass(class, color); use a unique string like "Scriptname Room". - When a zone class is registered, admins can use the tool to create new ones. - When a new zone is created, the "OnZoneCreated" hook is called serverside. See the example file for documentation. - When a zone is loaded into the game, the "OnZoneLoaded" hook is called serverside. See the example file for documentation. - When a player edits a zone's properties, the "ShowZoneOptions" hook is called clientside. See the example file for documentation. - - Use zones.FindByClass() to find all zones which are of a given class. - Use ply:GetCurrentZone() to find the zone that a player is standing in. - - Installation: - This is a shared file so include it in any shared environment. Also include ent_zone_point and weapon_zone_designator as a shared ent and weapon. - You should not put this file directly in lua/autorun. - - License: - YOU MAY use/edit this however you want, as long as you give proper attribution. - YOU MAY distribute this with other scripts whether they are paid or free. - YOU MAY NOT distribute this on its own. It must accompany another script. - - Enjoy! ~Bobbleheadbob -]] - -local table, math, Vector, pairs, ipairs, ents, bit = table, math, Vector, pairs, ipairs, ents, bit - -if zones then - local diff = math.abs(math.floor(version)-math.floor(zones.version)) > 0 - if diff then - ErrorNoHalt("WARNING!
