CNifAgentBase Class Reference

class CNifAgentBase : public CBase

Base class for agents. All agents derive from this base class; either directly or via another class that offers additional functionality. CAgentBase; CStateMachineAgentBase (for v6.1 agx porting)

since v9.5. Use MCPRs/CPRs/SCPRs instead of agents.
