How to slow down a game (with Chipmunk)

Hi,

I think I read that the cocos2d 0.8 release has this feature, but don't find this.

I want in some circunstances to slow down (like in slow motion) my flying Chipmunk sprites and this will be temporarily, just some seconds.

How to achieve this?

Thanks

I guess u can decrease cpSpaceStep delta time, and do not change delta time of call func. For example if u call update chipmunk func every frame(1/60) and u have cpSpaceStep delta time=1/60 means ur objects moves normally. Changing cpSpaceStep delta time to 1/120 will make them move twice slower.

Taken from cocos2D release notes:

// value
//  1: means standard speed
//  <1: slow motion values
//  >1: fast forward value
[[Scheduler sharedScheduler] setTimeScale: value];

Hope this helps.

Thanks,

@mikeJ, yes this works. I have done, but I was referring the new specs from Cocos2d 0.8 Will dig into both to see what fits better.

@natanavra, thanks will look into it.

Well ... putting 400 instead the regular 60 in te SpaceStep delta time will do the trick.

setTimeScale don't works if you set a value lower that 1 and putting a value higher does nothing (relative to Chipmunk)
