Classes

CBaseEntity

This is a script handle class for entities. All entities spawned have a script handle using this or one of its subclasses.

All script handles in-game are accessible from Entities. Entity scripts can use self to access their own script handle. activator and caller variables can be accessed on function calls.

Methods

Function	Signature	Description
__KeyValueFromInt	void __KeyValueFromInt(string key, int value)	Sets an entity Keyvalue from an integer. This simply changes the value without executing any code that may be needed for the entity to process the KeyValue, so there may be unintended side effects.

CEntities

Script instance: Entities

An interface to find and iterate over the script handles for the entities in play.

To iterate over a set of entities, pass null to the previous argument in the appropriate method to start an iteration, or reference to a previously found entity to continue a search. Example:

//The first way
local ent = null;     //The variable name "ent" is arbitrary.
while(ent = Entities.FindByName(ent, "entityname"))     //Indeed, we mean '=' and not '==' ! The loop aborts if "ent" becomes null.
{
  //...     //In every iteration, "ent" is not null.
}

//The second way
for(local ent;ent = Entities.FindByName(ent, "entityname");)     //The variable name "ent" is arbitrary. Indeed, we mean '=' and not '==' ! The loop aborts if "ent" becomes null. (All the semicolons are correctly placed)
