Activate() is a void member function of CBaseEntity that is available through inheritance to every entity in a Source game. It is called by the engine after Spawn() and, if Spawn() occurred during a map's initial load, after all other entities have been spawned too.
Activate() is used to perform spawning tasks that require interaction with other entities. Such tasks should never be performed in Spawn() itself, as it may be called before any other entities become available.
Warning:CBaseEntity executes code in this function, so always call BaseClass::Activate() from your version.
Note:If an entity is spawned from the console (ex:ent_create) or via game code (ex:CreateEntityByName()) then Activate() is not called so be sure to call Activate() from the spawning code. Also note that Activate() is not called for client-side entities..
Example
void CAlyxEmpEffect::Activate()
{
// Start out with a target entity
SetTargetEntity( STRING(m_strTargetName) );
BaseClass::Activate();
}
