thank you

Not enough information. Provide attempted program code and also details on how you tried to manually set the image.

You do not need smooth mover support on actors that only move up, down, left and right. Add any one additional direction and you may have a reason to use it.

You can use switch on char value in this way: <Code Omitted>

To be unobstructed, the ray is limited to only touch the two actors. It definitely must be less than or equal to two to be truthfully unobstructed. Whether the value used is two or zero is determined by the types of the two actors. If they are of "intersecting" type checked for, use 2. If only one of the two actors is of that type, use 1. If neither is on that type, use 0.

Thank you again danpost.

I am quite sure it is -- for that titan1 object. A different (or new) titan1 object would not show it (at least, none in your world would unless you added the same one back into the world).

Thank you, it worked.

No clue. Not available to download and no code provided here.

Add the following to the class: <Code Omitted>This constructor will initialize the image.

can you share the code of your button ?

Well, okay; but there should be a reason for dividing up the ids. Let's say you had one, like maybe you have 4 classrooms of 25 students each (classrooms 1, 2, 3 and 4) and you are listing which student is in which room. Then <Code Omitted>and looping through, displaying on screen (after loading ids into the array in similar manner) would be (in a world of least 600 x 560):

Add one manually, save the world, then look at the code in your world class (probably called MyWorld)..

Yes, addedToWorld(World) is part of the Actor class API. To use (aka override) the method, you must duplicate the name precisely and use the same number and type parameters in the same order. Anything else would be a different method altogether.
