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.

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.

The following are two equivalent examples and iterate over all weapons on the map:

local ent = null; while ( ent = Entities.FindByClassname(ent, "weapon_*") ) { // ... }

for (local ent; ent = Entities.FindByName(ent, "weapon_*"); ) { // ... }

 Note: 

• The variable name ent is arbitrary.
• Indeed, we mean "=" and not "==" in the loop conditions! The loops end if ent becomes null. In the {loop body}, ent is a handle of a weapon in the map and definitely not null.
• Semicolons are optional, except in the header of the for statement.
• The string parameters of the FindBy... functions support the wildcard star *. In the above example, FindByClassname only returns either a handle of an entity whose classname begins with "weapon_" or it returns null.

Methods

FindByClassname	handle FindByClassname(handle previous, string classname)	Find entities by their classname.

FindByClassnameWithin	handle FindByClassnameWithin(handle previous, string classname, Vector origin, float radius)	Find entities by their classname within a radius around an origin.
FindByModel	handle FindByModel(handle previous, string modelname)	Find entities by model name.
FindByName	handle FindByName(handle previous, string targetname)	Find entities by name.
FindByNameNearest	handle FindByNameNearest(string targetname, Vector origin, float radius)	Find entities by name nearest to a point.
FindByNameWithin	handle FindByNameWithin(handle previous, string targetname, Vector origin, float radius)	Find entities by name within a radius.
FindByTarget	handle FindByTarget(handle previous, string target)	Find entities by target keyvalue.
FindInSphere	handle FindInSphere(handle previous, Vector origin, float radius)	Find entities within a radius around an origin.
First	handle First()	Returns the first entity, typically worldspawn. Equivalent to Entities.Next(null)
Next	handle Next(handle previous)	Providing reference to a previously found entity, returns the next one in the list.
IsValid	bool IsValid()	Whether the handle belongs to a valid entity.

CSimpleCallChainer

Has the same members as CCallChainer. To do

LateBinder

Late binding: allows a table to refer to parts of itself, it's children, it's owner, and then have the references fixed up after it's fully parsed.

// Usage:
lateBinder <- LateBinder();
lateBinder.Begin( this );

Test1 <-
{   
   Foo=1
}   

Test2 <-
{   
   FooFoo = "I'm foo foo"
   BarBar="@Test1.Foo"
   SubTable = { boo=[bah, "@Test2.FooFoo", "@Test1.Foo"], booboo2={one=bah, two="@Test2.FooFoo", three="@Test1.Foo"} }
   booboo=[bah, "@Test2.FooFoo", "@Test1.Foo"]
   booboo2={one=bah, two="@Test2.FooFoo", three="@Test1.Foo"}
   bah=wha
}   

lateBinder.End();
delete lateBinder;

When End() is called, all of the unresolved symbols in the tables and arrays will be resolved, any left unresolved will become a string prepended with '~', which later code can deal with.
