adding omnidirectional attack animation

Replied to by RcCookie, over 5 years ago:

Hello Lewis, the problem with your code is that if the mouse is clicked at all both if-statements will be true. That means that the image is first being set to left or right but immediatly after that to up or down. Try this one:

Moving Background

By RcCookie, with no replies.

Hey guys, I´m currently trying to implement a camera package that allowes to show a part of the world. I´ve got the Actors moving across the screen in their relative position to the selected one and now I´m trying to get the background image moving, too. Unfortunatly I just can´t get it to work, it just draws a weird shape of images layed onto each other on the screen and the part that is actually moving only moves in 45°-angles. I did not use the move method but only setLocation, and I´ve got no idea how to fix this. I would really apreciate it if someone could tell me how to simply draw the background image at an offset position. Here´s the code I used so far (h is the Actor the camera shoud look at): <Code Omitted> Thanks for any help! RcCookie

Spawning objects at random?

By whattheheck, with 1 reply.
Replied to by danpost, over 5 years ago:

You cannot spawn objects from inside their class. Well, you can -- but the first must be spawned from outside the class and then they will spawn at an exponential rate that is not wanted. Have your world class randomly spawn the obstacles. The disappearing part can be done in the class of the obstacle.

showText error

By Mattzh, with 2 replies.
Last reply by danpost, over 5 years ago:

Switch the order of lines 62 and 63; then move line 21 to be between those lines. The error was trying to show text on the null reference returned by getWorld, as the actor was removed from the world already.

Pardon, it's in line 20. No need to help, though

Oh. So, ListNode is the BinaryTree class -- not List. I still do not see a 2nd constructor, however. Good luck.

You are probably using a newer version of greenfoot at home. Try commenting out line 2 and line 24. Next to line 24, add the following line: <Code Omitted>
