I have a base class called Attacker that has a update method. The update method moves attacker through an array of waypoints as given below:
- (void) update:(ccTime)dt {
if(state == kMove) {
// code to move to next waypoint
// on reaching the next waypoint, update the next waypoint variable
// if the final waypoint is reached, then stop the movement of attacker
}
}
So, the base class takes care of simple waypoint movement logic. Now I derive a few classes like Rifleman, MachineGunner, Engineer from the Attacker class.
Now I want each of the derived class to do a specific action on reaching the final waypoint. For eg., I want the Rifleman to change to attack stance, the machine gunner to deploy and setup his gun, the engineer to start constructing a defense.
How do I achieve this? My current idea is to check for final waypoint condition in the update method of each of the derived class and do the corresponding action.
- (void) update:(ccTime)dt {
[super update:dt];
if(state == kMove) {
// if the final waypoint is reached, then do class specific action
}
}
Is there any better way of doing this?
