Game is getting slower after each play

Hello, it seems like after each playthrough, the game gets slower after each play. I thought it was an issue with cache, http://blogs.unity3d.com/2012/10/26/in-depth-cache-server/ http://docs.unity3d.com/Manual/Preferences.html but I don't think that's the issue.

The solution is just to restart unity (but after a few plays, it goes back down to 20-30fps). My problem is, will this happen on an actual build, where after each playthrough, the game gets slower and slower?

Note: I felt more like forums because I want people to discuss if they experienced anything like this before.

 

Export and try? Takes like what 10-15minutes?
But i highly doubt that would happen in an actual build since, as you said, when you restart unity it's working again.

Other than that, can't say i have experienced something like this yet.

 

Sounds like a memory leak. Have you checked the profiler? Does it happen only on that game, or all your projects?

 

I haven't tried on other projects, but it does happen in all scenes though.

After reading these, it does sound like a memory leak (thanks zombiegorilla). I found a wiki page that shows me how to find the assets that are causing trouble.

However, I didn't really find anything that tells me what to do after. Is it as simple as just not reference these assets in my script?

 

One common cause is creating objects and destroying or reusing them. Not sure what your game is, but are spawning things regularly, like bullets/missles/fx, or things of that nature? If that is something your game does, and if turns out to be part of the problem, pooling is good way to close that hole. You can use the profiler to root out the problem as well. Watch your game for a while, as it starts to slow down, you should see something in the profiler increase, that should help narrow it down.

 

Yes exactly, I'm using missiles and fx. I'll look into pooling. Thank you
