### Remarks

This is the approximate amount of system memory in megabytes.

**WebGL**: This function will return the current size of the asm.js/WebAssembly heap. Note that when using WebAssembly, the heap size can increase at run-time if the Unity content memory-usage exceeds the [initial memory size](/engine/6000.0/script-reference/unityeditor/playersettings/webgl/memorysize.md). **Windows Store Apps**: This function is not supported on Windows Store Apps and will always return 0.
