Variable Prefixes

Prefix Description
object.var accesses the variables of the object. The object can be retrieved by using the case-sensitive name of the object or a variable pointing to the object.
this.var variables that belong to the current script object, on the server-side they are saved to file when the object is a database npc
thiso.var refer to the this. variables of the executing npc ('o' stands for original) when you use the with () command: with (findnpc("npc2")) thiso.temp = this.temp; will copy 'this.temp' from npc2 to the current npc
player.var variables of the current player object, when the event was invoked by a player (e.g. playertouchsme), or you do with (findplayer(accountname))
playero.var variables of the original player object, in generally the player who has invoked the event (e.g. playertouchsme)
client.var short for player.client.var, variables that can be changed on server-side and client-side
clientr.var short for player.clientr.var, variables that can only be changed on server-side but can be read on client-side
server.var variables that only exists on server-side and can be accessed by all npcs
serverr.var variables that can only be changed on server-side and is server wide, but can also be read by all clients, so it can be used for storing the state of global activities that need client-side actions like displaying weather; like server. vars they can also be changed with remotecontrol.exe by administrators that have the right to change server. variables
level.var variables of the current level, which is the level the executing npc stands in (on server-side) or the player is in (on client-side)

triggeraction(float x, float y, str eventname, params...) Invokes an "onActionEventname" event on objects at the specified position, can be used to invoke events on objects from clientside to serverside and vice versa.

Special eventnames are "serverEventname" which will invoke an event on the Control-NPC (onActionEventname), or "serverside" which will invoke an onActionServerSide event on the weapon script specified by the first following parameter (the fourth parameter). It is recommended to use triggerserver() for that though.

Example: 

triggeraction(30, 30, "explode", 5);
triggeraction(0, 0, "serverchat", player.chat);
triggeraction(0, 0, "serverside", "PlasmaGun", "activate");
triggerserver(str objecttype, str objectname, str params) Invokes an event on a serverside object, currently objecttype can only be "gui" or "weapon" (which is the same), objectname is the name of the weapon script, the invoked event will be "onActionServerSide".

On Graal3D the event will be "onActionParam0" instead. For invoking events on the clientside use player.triggerclient(objecttype,objectname,params) instead.

Example: 

triggerserver("weapon", "PlasmaGun", "activate");
updateboard(int x, int y, int width, int height)
updateratings(obj) object Updates an array of {rating1,ratingdeviation1, rating2,ratingdeviation2, ...}, init them at 1500 and 350.

Example: 

newratings = updateratings({winner.rating,winner.ratingd,loser.rating,loser.ratingd});
winner.rating = newratings[0];
winner.ratingd = newratings[1];
loser.rating = newratings[2];
loser.ratingd = newratings[3];
wraptext(int fontsize, str format, str text) array of strings
wraptext2(int pixelwidth, float zoom, str delimiters, str text) array of strings wraps the text so that it fits in the specified number of pixels and returns an array of text lines
