Physics Chipmunk. Ball goes through all walls

[Dynamite]

Hello,
I have been working in my major project for quite some time and I was impressed with the fantastic progress.
One day I began to add more levels in it and suddenly when I ran the application the ball went through all the walls! I always run my application after I add some obsticle and the ball never went through the walls. I dont understand why this is happening.

I have made an incredible amount of post and noone has replied. I really hope this post doesn't turn into one of those.

I'm interested in this as well. I tried to use the example of pinball as base for my own pinball scene and the ball when going too fast went through defined walls. I changed 'time step' parameters as suggested but couldn't manage to work properly. I do believe it has something to do with the limitations of Chipmunk engine:

Known Issues

"Fast moving objects sometimes pass right through one another. Use smaller time steps if this is a problem."

My ball isn't moving fast at all.

[Bruto]

Then you should play with iterations, time step values, etc. I got good results when object wasn't moving too fast.

[Dynamite]

Yes but the thing I dont understand is the game ran perfectly 1 minute before the ball went throught the walls. I didn't change any settings.

Upload an example, that way you have more chance with people helping you.

It is like telling Nifflas to upload Night Game

Maybe could you upload an example that shows just the problem, not the entire game?
I would be very interested to see the cause of this problem.

[JasonDarby]

Yes but... reduce the size of the file to where the problem still exists.

If you want people to help you with your problems, then uploading a file is the best way.

I was about to upload it until I found out the error. I think this can help Bruto_Memo as well.

The error was when I create the body the position is 0,0 but when I add a circle the possitions are different.

I made both possitions the same so now it works fine

Also, I still need help with this (The post got lost ) http://www.clickteam.com/epicenter/ubbthreads.php?ubb=showflat&Number=78953#Post78953
