CallbackBase Class
| Header: | #include <UnigineCallback.h> |
A base class for engine callbacks.
This class allows you to create your own callbacks with up to 5 arguments.
Usage Example#
This section contains the simple CallbackBase usage example.
In the header file:
Source code (C++)
#include <UnigineLogic.h>
#include <UnigineStreams.>
#include <UnigineCallback.h>
class AppWorldLogic : public Unigine::WorldLogic {
public:
/* other methods */
// function
void setNewCallback(Unigine::CallbackBase *cb);
private:
// Callback function
Unigine::CallbackBase *callback_func;
};The implementation file looks like:
Source code (C++)
#include "AppWorldLogic.h"
#include "UnigineCallback.h"
using namespace Unigine;
CallbackBase *func;
/* other methods */
void AppWorldLogic::setNewCallback(CallbackBase *func) {
callback_func = func;
