As you can see from the class definition, really the only methods that have any meat
to them are the response to the left mouse button and
OnUpdate()
. Keyboard
events are recorded as they happen, which are used in
OnUpdate()
.
Here
'
s what happens when the player presses the left mouse button:
bool TeapotController::VOnPointerButtonDown(const CPoint &mousePos,
const int radius, const std::string &buttonName)
{
if (buttonName !=
“
PointerLeft
”
)
return false;
ActorId actorId = m_object->VGet()->ActorId();
GCC_ASSERT(actorId != INVALID_ACTOR_ID &&
“
The teapot controller isn
'
t attached to a valid actor!
”
);
shared_ptr<EvtData_Fire_Weapon> pFireEvent(
GCC_NEW EvtData_Fire_Weapon(actorId));
IEventManager::Get()->VQueueEvent(pFireEvent);
return true;
}
