R0j0, how are you profiling the chipmunk performance? I'm quite a newcomer to Chipmunk, but I've been trying to understand its structure... so I ran a test on IE and Chome, and started investigating what could be the reason behind slowdowns... for me the most time is spent on BBTree.prototype.reindexQuery - it feels like almost an infinite nested loop - each prototype.markSubtree contains another prototype.markSubtree inside.

The tree becomes so nested that it's impossible to show on a screenshot. I'll include few screenshots (on the second screenshot you can see there's some anon_func happening under the Leaf.prototype.markSubtree):

*EDIT* too little rep to post urls, I hope this works:

In my experience, the runtimes spent on individual Node/Leaf .prototype.markSubtree and Node/Leaf .prototype.markLeafQuery are growing as they nest. Could BBTree.prototype.reindexQuery be the source of the memory leak?

Just a quick question: Is Chipmunk only meant to function, if you apply it to objects separately instead of applying it straight to a family?

I tried applying Chipmunk to a family of objects (a ragdoll), in a similar way I used to work with Box2d, but as a result I get black screen. Loading of the layout freezes at 30%. However, if I remove the Chipmunk behavior from the family and apply it separately to all the objects in the family, the layout loads and everything works fine.

EDIT:

I guess it was just some gibberish in the cache, now everything is working fine So one can apply it straight to a family for all the objects in the family inherit Chipmunk =)

Kudos! I just started a code revision on my game project and was planning to switch the physics engine - R0j0hound really saved my day! Excellent job as always =)

Thanks also to Prominent, was facing the same issue. Wish a great weekend for you guys!

Yeah same problem, but as is always the case Ashley will fix it pronto.

Always remember to make backup before opening in latest beta, this is the nature of beta testing !!

That's a good point, but having backup is only one thing working in construct2 is so effective that in most cases it does not make much sense to work on the dated backup anymore if you've worked the idea further on a working beta release.

For example, I have been doing 10-15 hour days on the game, so reverting back to r184 does not make any sense (losing 9 days of work, around 100 hours.. that version of my game project is missing so much of the features that it would be pointless to try to remember reworking everything on it). Now I just have to focus working on the graphical assets and hope this thing gets fixed really soon or that they put beta r187 that's actually the old 185 for us poor steam users, who didn't think about this happening :/ The bright side is that now I know I have to make sure I buy traditional desktop version license key when I buy the business upgrade next year, since testing beta releases on steam puts your project just on too much of a risk

Here's a link to a .capx on which this problem occurs, in order for others to replicate.

It's a real bummer indeed that I got the steam version, now my game project has to be on hold =/ and I'm a bit on a hurry on it I should have thought twice before putting on the automatic beta updates, didn't realize there's no way to revert the version on steam.

I just got the exact same error - prototype of the game that earlier ran well (r185) no longer runs with this release of Construct2 (r186). My system configuration is the same as yours, so you just saved my time for typing this bug report - thanks

To make things worse for me, I don't know how I can revert back to r185, since I have bought the full personal edition on Steam... does anyone know how to revert to older version of Construct2 on Steam? =/

ahh it's on newgrounds . com -> search for game 0302.. it's the only game there. Unfortunately I'm not allowed to post URLs still here at the forums.

The game doesn't work for me, it hangs if I try to skip the intro and also when I go through the intro it hangs before getting to the game. I'm using Chrome browser.

Thanks for arranging the contest, the theme is really inspiring and C2 as a tool is simply amazing. I posted an entry too, but can't post a link here yet =P it can be found on newgrounds though easily (named 0302)

Searching for slope delivers only this thread (at least for me, I'm also interested in this, so just chiming in

I'm not sure if you can use Microsoft's SkyDrive, that one can perhaps be worth testing And of course own hosting gives you the most freedom over how you present the game to the users.

Thanks for compiling the list. There are some resources I hadn't bumped into before =)
