In my game, obviously I want to keep memory usage as low as possible, and most importantly avoid memory leaks. However, looking at the memory profiler I've noticed that the value for mono slowly increases over time. Currently, it starts at about 14.3 mb, and then increases to about 21.0 mb after about 5 minutes or so, before going back to it's initial value (When I assume the garbage collector kicks in). Now, this definitely seems like it's probably not a huge issue, but if there's a way to avoid it then I'd like to take care of it now and figure out what's causing it, so I can avoid the issue going forward and prevent making it even worse as I add more objects and scripts. Oh, and I'm testing this in a build so I know the profiler isn't tracking any editor scripts. My scene has very few updates running in it, and the objects that do aren't creating any new objects or instances or anything. So what I'm wondering is, is this just normal behavior with Unity or C#, or is it likely that something somewhere is leaving behind unnecessary data? For example, my camera script, one of the few objects with an Update function (Technically LateUpdate), has a local int created each time it is called. Could this be part of the issue (Assuming this is an issue)? Does this int not get automatically removed from memory when the function finishes, and if not should I be doing so manually? Similarly, my player movement script contains "playerRotation.eulerAngles += new Vector3(xStuff, ySuff, zStuff)" in its update. Does playerRotation's previous vector3 never leave memory until the garbage collector is called? Should "new" be avoided in updates? These are the only things I can find that I think could be causing this issue, again, assuming it is an issue. I also use Rewired for handling input, so it's possible that is also contributing. I've tried doing some research on the memory profiler and memory leaks, but I can't seem to find any guides or tutorials explaining how to best avoid memory leaks in scripting (Besides some of the very obvious things) and what is considered normal in regards to how quickly memory usage increases. Thanks in advance for any help!
