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;
}
