Problem Overloading Function

[Phlox Icon]

I've successfully bound an overloaded function before but this one is giving errors.

It's of the CAI_BaseNPC class. The function I'm trying to bind is the top one here.

CAI_Motor * GetMotor() { return m_pMotor; }

const CAI_Motor * GetMotor() const { return m_pMotor; }

I thought maybe it was because of missing includes or something so I put them in. Here's the code that generates the error.

#include "ai_basenpc.h"

#include "ai_motor.h"

class CAI_Motor;

....

.def( "KeyValue", (bool(CBaseEntity::*)(const char*, const char*)) &CBaseEntity::KeyValue ) // overloaded fine

.def( "GetMotor", (CAI_Motor( CAI_BaseNPC::* )(void)) &CAI_BaseNPC::GetMotor ) // generates error

There are quite a few erro messages but they're all pretty much the same after the second one.. These are the first two.

error C2440: 'type cast' : cannot convert from 'overloaded-function' to 'CAI_Motor (__thiscall CAI_BaseNPC::* )(void)'

Any ideas? Thanks.

You're returning a CAI_Motor* but your cast says you're returning a
CAI_Motor.

Holy crap. I don't know how I overlooked something so obvious. I'm quite embarrassed to have sent this now :S

But thank you very much, James. Well spotted. I owe you one. :D
