How can I make a object "solid"?

By Sciyaps, with 1 reply.
Replied to by dlanni, over 12 years ago:

There is a method in Class Actor called getOneIntersectingObject and several others that might fit your situation. You can use these methods to sense when one object intersects another. Maybe make a method based on the ever popular crab scenario's canSee method, whose code is downloadable (although they usually use the less useful getOneObjectAtOffset). My game, PyroTyro, uses the first method. The code is available; just open the House class. After one car "canSee" another (they collide), you can remove both of their images and replace them with a crunched up car image, just as I have rep

Thnaks a lot for your replies, I was thinking in an array of images like davmac said. I'm not sure if there is a difference in usgin == or equals but the use of equals sounds more for usefull for Strings. Thanks a lot for the tips Duta and davmac!!!

We do have a bug in recent versions of Greenfoot

Indeed, the code above contains the same bug. Line 04 should be removed, because setLocation(...) already takes cell size into account.

Yeah the problem is it doesn't actually go in the direction you're facing necessarily (especially at angles like 30 degrees and similar). Will this be fixed in the next release?

That is an issue with accuracy of position; you can fix it by moving in larger increments, or by using the SmoothMover class. It won't be "fixed" in the next release because it's arguably not a bug.

Greenfoot Not a 32-bit application?

By ianroberts, with 4 replies.
Last reply by nccb, over 12 years ago:

I just tried it on my 32-bit XP machine, and it worked fine. It could be a corrupt download/incomplete ZIP extraction, but that seems unlikely. How exactly are you attempt to run Greenfoot? Are you auto-running the stick, using the "Run Greenfoot" shortcut on the stick root, or running Greenfoot in the greenfoot directory on the stick? Post here which one you're using, and maybe try one of the others in that list to see if they work.

Altering stack space

By danpost, with 7 replies.
Last reply by danpost, over 12 years ago:

@davmac, thanks again! I did find the problem. Actually, there were two (related). (1) I had a 'while' where there should have been an 'if' (when removing paired parenthesis) (2) needed an 'else' after that same 'if' statement The location was in the 'evalFactor' method of the 'Graph' class. You can change that in your copy to have a corrected one. The 'while' statement was immediately before the 'if (isFunction(factor))' statement.

I'm obviously getting better at this because I actually understood what that was doing just by looking at it :) This worked perfectly! Thanks!!!

You don't have to use it, its just a suggestion so that your thing is better! It shouldn't take long to implement anyway hopefully.

How to flip image

Last reply by davmac, over 12 years ago:

what is difference between wait and delay and which one should I use for an explosion actor?

'wait' is a Java method which you shouldn't use. Use Greenfoot.delay(...).
