![]() ![]() The program comes with a sample collection to get you up and running, but you'll need to create a new database once you want to actually start cataloging your own comics. Like most other database-oriented applications, Comic Collector doesn't boast a fancy, modern design, but the three-paned interface is rather self explanatory. You can enable the full call stack traces for GC.Alloc samples, which then helps you determine where and when the garbage collector ran.This utility offers a number of tools for organizing your collection of comic books. More info See in Glossary to determine which method the allocations happen in. For example, it can report the percentage of time spent rendering, animating, or in your game logic. It shows how much time is spent in the various areas of your game. You can also use the Call Stacks mode in the Profiler A window that helps you to optimize your game. The Unity Editor works in a different way to a build, and this affects the profiling data for example, the GetComponent method always allocates memory when it’s executed in the Editor, but not in a built project. More info See in Glossary on the target platform or device you want to build to. To get the most accurate information, you should always profile your application on a development build A development build includes debug symbols and enables the Profiler. This means that the sum of the GC Alloc over all frames doesn’t total how much the managed memory grew in that time. It also displays the amount of memory that the garbage collector managed, and it includes memory that Unity might have allocated and reused in subsequent frames. This column displays the number of bytes that Unity allocated on the managed heap in a specific frame. In the CPU Usage module, the Hierarchy view contains a GC Alloc column. The Memory Profiler package: A separate Unity package which provides detailed information about memory usage during specific frames in your application.Unity Profiler’s Memory module: Provides high-level memory usage frame by frame.Unity Profiler’s CPU Usage module: Provides details of the GC Alloc per frame.Unity has the following tools to keep track of memory allocations: Disable automatic garbage collection: Use the GarbageCollector.GCMode API to take full control of when Unity should run the garbage collector. ![]() Incremental garbage collection disabled: If you disable the Incremental GC Player Setting, the garbage collector stops running your application to inspect and process objects on the heap.Incremental garbage collection: Enabled by default ( Project Settings > Player > Configuration), this mode spreads out the process of garbage collection over multiple frames.In Unity, the garbage collector has the following modes: For more information, see Garbage collection considerations. The Unity WebGL build option allows Unity to publish content as JavaScript programs which use HTML5 technologies and the WebGL rendering API to run Unity content in a web browser. Note: The garbage collector works differently in WebGL A JavaScript API that renders 2D and 3D graphics in a web browser. The process of locating and freeing up unused memory is called garbage collection (GC). To determine which heap blocks are no longer in use, the garbage collector searches through all active reference variables and marks the blocks of memory that they refer to as “live.” At the end of the search, the garbage collector considers any space between the “live” blocks empty and marks them for use for subsequent allocations. If all references to a memory block are missing (if the reference variables have been reassigned or if they’re local variables that are now out of scope) then the garbage collector can reallocate the memory it occupied. More info See in Glossary can only access a reference item on the heap as long as there are still reference variables that can locate it. ![]() Universal Windows Platform, however, supports only two. Unity supports three different scripting backends depending on target platform: Mono. Unity’s scripting backends A framework that powers scripting in Unity. In this situation, it’s unlikely that all allocated memory is still in use. The garbage collector handles subsequent requests in the same way until there is no free area large enough to allocate the required block size. Unity then deletes the unreferenced objects, which frees up memory. When the garbage collector runs, it examines all objects in the heap, and marks for deletion any objects that your application no longer references. When a script tries to make an allocation on the managed heap but there isn’t enough free heap memory to accommodate the allocation, Unity runs the garbage collector. Unity uses a garbage collector to reclaim memory from objects that your application and Unity are no longer using. ![]()
