Re: Searching

it shouldnt take this long to fix the forum i think, we need "view new posts" and search asap :)

Re: Force/Impulse timebase

after reading ur post i realize its more complicated than i first thought, but my change makes things more deterministic in my "usage" of bullet, i only apply forces when simulation steps i think u have to synch ur external force applications with actual sim steps ill think about it and get back if ...

Re: Force/Impulse timebase

I agree that with the internal substeps, it is better to clear out the user force _after_ all substeps completed. It will be fixed for next release (2.65). Other physics SDKs, like Havok and Ageia also clear out the force after the simulation step I think, but I need to verify. Thanks for the feedb...

Re: Force/Impulse timebase

i have also run into this force problem in combination with sub steps, i really think this behaviour needs to be looked over if force applying should be usuable/predictable when i started to use bullet i was surprised that forces were reset this way, can someone explain the logic/good of forces bein...

Re: Bullet in 2D?

do this work for you ?

btw, when i searched this forum to find this topic using "bullet in 2d" as search phrase it failed saying that words are too common or too short, hopefully this can be improved

Also, you can still apply impulses during the interpolated simulation steps. See the demo (link not allowed in first post): run the demo, bring up the console, type pbullettime 0.01 and shoot at the tower blocks. The applied impulse immediately effects the linear/angular velocity, but the interpola...
