I like to use user events for these kind of things.
Put all your code inside the event_user(0).

if (something happens)
{
    with(obj_object)    // This will go through all the instances of the obj_object.
    {
        event_user(0);
    }
}

when this happens
{
with(obj)
{
DO THIS
}
}

Oh, I thought that the with only works for different instances of an another object... Thanks guys!
