Losing framerate on low end android

billydb · March 2018

I fixed a memory leak that I thought was causing the frame rate to drop after reloading the same level several times but it still happens. In the profiler it says the memory is stable but every time i re enter any level i lose a couple of fps untill it's unplayable. I'm using TIled and box2d physics and I used a few scripts called bhleaky to test there's no memory leak anymore. Completely stuck on where to look. So what could cause a frame rate drop after loading levels multiple times with the scene manager that isn't because of increased memory consumption? Thanks

Sounds like a variable that isn't being reset when you reload the level. Like an iterator in a loop?

Thanks for the suggestion, gives me somewhere else to look at least

If you are using Box2D then I would have a good look in that code to make sure you are destroying everything between levels.

Does it play okay on the first level?

If memory is stable it's probably unessecary work that's the culprit, rather than objects not being removed.

It was large images loaded by the level to the stage that weren't being removed. Really obvious and dumb issue but partly didn't catch it because the memory use was stable so I ruled that out. Or is there something I'm not getting?

Great that you found it! If new images were being loaded and not removed, it would have shown on the memory. So strange!
