new creatureevent function (onCritical)

[Cosmotonio]

hi, someone can help with this error?
i changed this in weapons.cpp:

player->sendCriticalHit();

to this:

            //scripting event - onCritical
		CreatureEvent* eventCritical = getCreatureEvent(CREATURE_EVENT_CRITICAL);
		if(eventCritical)
			eventCritical->executeOnCritical(player, target);

but i get this error:

689 D:\Leandro\Server\TFS Source\0.3a4\weapons.cpp invalid conversion from `const Creature*' to `Creature*'
