Using Backtrace to detect errors and exceptionsīacktrace allows developers to integrate crash handling into their apps, capture and monitor errors, prioritize issues to work on, and get everything they need to debug the problem in a single interface. The following best practices can be adopted to reduce garbage collection and potential out-of-memory issues arising from the lack of garbage collection in between frames in a WebGL build:

The code on the right is rewritten to avoid concatenation and therefore avoids memory allocation in intermediate string objects, which over time would result in unnecessary garbage collection and performance bottlenecks.īest Practices to avoid out-of-memory issues involving GC In the following example, a countdown timer is continuously updated but the code on the left uses a string concatenation to concatenate the prefix with the countdown time.
The following code will work fine in non-WebGL builds because the GC would get a chance to get invoked in between iterations of a loop to clean up the memory used by the intermediate string objects but it could run out of memory (OOM) in a WebGL build:Įxample: The above for-loop could result in an out-of-memory errorĮven if you do not run into OOM (Out of memory) issues, it is always a good practice to avoid concatenating strings unnecessarily. This is why GC runs once after each frame is rendered, as this is when the stack (which is a part of the Unity Heap) is empty. The primary condition for the GC to run on WebGL is that the stack must be empty. On non-WebGL platforms, all running threads are paused to give time for the GC to check the stack but due to limitations in Javascript, this is not possible in WebGL builds. Typically, the GC locates and collects unused memory and then reallocates it in the Unity Heap. The last important consideration with regards to Unity WebGL builds is the Garbage Collection (GC). And this is exactly why it is very important to keep the heap size as small as possible. This resizing feature however, can often cause your WebGL game to crash, especially in cases where the browser fails to allocate one contiguous block of memory. Until a few years ago, you had to allocate the maximum size of the heap in the project build settings but now Unity supports automatic resizing of the heap to adjust to the needs of the game, and is expandable up to 2GB. It is worth noting that this heap is one contiguous block of allocated memory. These run time objects include native objects, assets that are loaded, scenes, shaders, animations as well as other managed objects.

Additionally, they can be loaded and unloaded on demand and they free up memory on unloading.Ī common feature to all build platforms in Unity is that every runtime object is stored in a memory heap that Unity calls ‘Unity heap’ or ‘Unity memory heap’. It is even more crucial in the WebGL platform to use Asset Bundles because they load directly into Unity Heap and require no extra allocation by the browser.
Asset Bundles can be used effectively to manage memory allocation. The techniques applicable to build platforms on mobile devices can be applied here too. It is clear that WebGL builds require efficient management of memory and in order to reduce the uncompressed data file during your app/game’s runtime, you will need to reduce the data file size. Reducing memory use by using Asset Bundles Therefore, a WebGL game with a complex 3D scene involving many assets may slow down and potentially risk running out of memory. This memory file system is allocated in the browser's memory space by Emscripten and the browser retains the uncompressed data file during the game’s runtime. This data file contains all the assets and scenes the game requires at the time of launch.Īs Unity WebGL builds can’t access the real file system, they create a virtual memory file system (VMFS) in which their. data file whenever you build a WebGL game. The Unity WebGL app requires the web browser to allocate plenty of memory in certain cases.

The browser allocates the memory in its memory space that your app needs to run your content and the amount of available memory varies depending upon various factors such as the type of device, the type of operating system, the type of browser and whether it is a 32 bit or a 64 bit browser, to name a few.
The complexity of the content that the Unity WebGL apps can run in a web browser is primarily constrained by memory. This blog explores the best practices and strategies pertaining to the performance of Unity WebGL builds and identifying and dealing with issues that lead to a WebGL app running out of memory (OOM). One of the major challenges that Unity WebGL developers face is to avoid performance issues that could lead to a negative gaming experience. There are many challenges involved in developing apps and games for WebGL builds in Unity.
