这是我的消息结构:
struct tEventMessage
{
// Type of the event
int Type;
// (void*) Allows those to be casted into per-Type objects
void *pArgument1;
void *pArgument2;
};
我可以在这个结构中添加某种“模板”成员,以便稍后在构建消息时我可以传递这些指针 + 和我希望的任何其他数据?(见下面的例子)
struct tEventMessage
{
// Type of the event
int Type;
// (void*) Allows those to be casted into per-Type objects
void *pArgument1;
void *pArgument2;
// Template
T tSomeTemplateMember;
};
void HandleClick(....)
{
CVector3 vNewPosition = ....
tEventMessage _msg;
_msg.Type = xxxx;
_msg.pArgument1 = pA->GetObjectPointer();
//
// Wrong!
// Because this CVector3 will not be alive in next tick
// - my pointer will point to nothing.
//
_msg.pArgument2 = static_cast<CVector3*>(&vNewPosition)
//
// Something like that would be great
// And would allow me to use CVector2,CVector3,CVector4 with one template member
//
_msg.tSomeTemplateMember = vNewPosition;
}
