How do take a bunch of actors and place them into a group?

If you want to contain a list of actors, I suggest storing their Actor *s in an array, or similar. You can do that or store their clonenames in an array, and get any Actor * by using getclone. This way if you want your functions to act on all actors within the group, you just use a loop.

Code: Select all

Actor * groupA[10];

void
moveGroup (int X, int Y)
{
    for(i=0;i<10;i++)
    {
        groupA[i]->x+=X;
        groupA[i]->y+=Y;
    }
}


If you need to use a built in function, you can access the individual actors like this.

Code: Select all

ChangeAnimation(groupA[i]->clonename, "animationName", FORWARD);

Here are two ways to set the array.

Code: Select all

groupA[0] = CreateActor("actorName", "animationName", "(none)", "(none)", 0, 0, true);
// this creates actorName and groups it into the array

// if the actor is already created you will have to use getclone, or getclone2
groupA[0] = getclone("actorClonename");

I sort of understand that but how do I creat the group?

That first bit of code is meant to be in global code. You have to declare it there. The size of the array is equal to the max number of actors in the group. Just put it there, give the script a name, and click add.

Global Code

Code: Select all

Actor * groupName[groupSize];

Also if you want to remove an actor from the group, just say the fifth actor, you can either set a different actor to it, or do this.

Code: Select all

groupName[5] = NULL;
