I know of setLocation(100,100);
but how do i say setLocation of a different class? setLocation(player.class 940,70)???
I hope i've explained it well enough.
Thanks.

how to setLocation of a different class?
You don't set the location of a class - you set the location of an object. You can set the location of any object that you have a reference to by qualifying the setLocation method call.
For instance if you have a variable 'otherActor' containing a reference to the object you want to set the location of, you can call:
If you don't know how to obtain a reference to the other actor, start with tutorial #6 and then ask further questions here if necessary.
1 | otherActor.setLocation(100,100); |
so far i've got this? but i get a terminal window popping up with red java errors.
1 2 3 4 5 6 7 8 | public void hit() { Actor ball; ball=getOneObjectAtOffset(0,0,GoldenBall.class); { ball.setLocation(100,100); } |
The good ol' NullPointerException throw.
If no GoldenBall object is intersecting the location at the offset given, 'ball' will be set to 'null'. You cannot set the location of a 'null' object reference. You must ensure that 'ball' is not 'null' before using 'setLocation' on it:
1 2 3 4 | if (ball != null){ ball.setLocation(100, 100);} |
