Why only last command works

By Marrryanx, with 1 reply.
Replied to by danpost, over 9 years ago:

Because all possibilities are covered by the first two condition (either the first one is true or, if not, the second one must be true), the last two conditions are never a consideration. Either use the same button class for both buttons (with possibly different text) or disconnect the 'if's by removing the 'else' at line 11 and check which world the actor is in before asking about each button.

You have shown part of a subclass of Actor. I asked for you to show ALL codes you have created (meaning entire class codes of ALL subclasses of World and Actor. I do not know if you even have a subclass of World, which is required, yet.

Oh yes, you are right, thank you. I probably missed that because I have never used that method myself... or because the method in the Animal class is named atWorldEdge.

Preventing collision of player with other classes

By wym, with 1 reply.
Replied to by danpost, over 9 years ago:

If you mean you are trying to have the player stop when a tree is encountered (so that they do not intersect each other -- that kind of 'prevent collision'), then your Tree class should simply be this: <Code Omitted>and you should have the player that moves check for trees and stay off of them.

If this is in a world subclass, simply remove 'getWorld().'.

java, and i figured out how to do it using a key, but each time i swap through words they reset, how can i fix that?

Do not create another world of that type. Maintain a reference to the world and set it active again when needed.

File cannot be null in array of Images

By Huntwa, with 3 replies.
Last reply by Nosson1459, over 9 years ago:

A side thing which I noticed in your code is that you have your for-loop going from 1 - 12 instead of from 0 - 12 for your "<Code Omitted>" (Arrays are zero-based so they start from 0 and go to one less than the number you put in, which you obviously know already because of "i<13").
