Detailed Description

A data class for creating message plugins.

Here is an example of a message plugin, which CoreMessage() method is called each 100 ms:

#include "c4d.h"
#include "c4d_symbols.h"

class TimerMessage : public MessageData
{
  virtual Int32 GetTimer(void);
  virtual Bool CoreMessage(Int32 id, const BaseContainer &bc);
};

Int32 TimerMessage::GetTimer()
{
  return 100;
}

Bool TimerMessage::CoreMessage(Int32 id, const BaseContainer &bc)
{
  if (id==MSG_TIMER)
  {
    // Do something
  }

  return true;
}

Bool RegisterTimerMessage(void)
{
  return RegisterMessagePlugin(1234567, String(), 0, NewObj(TimerMessage));
}
