Can An Actor Use Add Object
You asked if an Actor can use addObject. You really mean one of two things:
(1) can an Actor object add a new object of a different type into the world; or,
(2) can the addObject method be used in an Actor subclass;
Answers:
(1) yes, any Actor object of any type, new or otherwise, can be added into the world by any Actor object that is either in the world or that contains, or has access to, a reference to the world the object is to be added into; an Actor object already in the world can use 'getWorld' to get the reference and the line would look like this:
(2) from (1), we see that it is possible; to use a reference, here is code to remove and add back in the actor itself:
1 | getWorld().addObject(< Actor actor >, < int x >, < int y >); |
1 2 3 | World world = getWorld(); // the reference to a world (the one the actor is in, in this case)world.removeObject(this);world.addObject(this, 50, 200); |
