Garbage collection

(1/1)

Thomas.:
How can I optimize code for Android garbage collection? GB takes every 5 seconds about 70ms...

EgonOlsen:
Create less garbage... ;)

Regarding jPCT, make sure that you are using the methods that take the return value as parameter where possible (like getTranslation(<SimpleVector>) instead of getTranslation()).

Thomas.:
Thanks, these methods helped ;) I checked whole my code and there also were a lot of garbage. GC is called every 7 seconds, now. My measuring shows, that the largest memory allocation causes calling method checkCollisionEllipsoid(). Is there any possibility for optimization this method?

EgonOlsen:
No. Object creation of this method has already been reduced to the bare minumum. You can avoid some additional object creation if you don't use collision listeners, but that's about it.
