Maturain Bug #4

Closed anirul closed 7 months ago

anirul commented 7 months ago

Discover that sometime the position of the character is switch to -inf and also the dt... why?

mlaagerc2c commented 7 months ago

Sounds like overflow…

anirul commented 7 months ago

Yea but why? I do all my calculation in double so this is a bit weird. Also this happen from one frame to the next there is no intermediary, if it was an error accumulating it would not be like that.

anirul commented 7 months ago

I wonder if this does come from the dt going wild? like if you try to move to somewhere very fast then it could corrupt the position as fast? Still experimenting...

anirul commented 7 months ago

I hard corrected one of the error but I still have a camera issue... still working on it!

anirul commented 7 months ago

So... I thinks this is ok now. This was coming from the camera as I m not using any quaternion for it it sometime freak out and put Nan in the position of the forward vector (that contaminate the whole thing after). So I just detect when this is happening and reverting the forward to a safe direction and it work.

anirul commented 7 months ago

This is a memory corruption somewhere...

anirul commented 7 months ago

This was in effect coming from the async implementation, I reverted it 'painfully' and now it seams not to be there anymore.
