Using Unity's WebGL export in Node.js
We have made a development export to WebGL. This runs fine in the Browser, however we are trying to make it run as a headless unity server.
In the source-code we see several references to Node.js support, such as ENVIRONMENT_IS_NODE and the following included snippet:
requestAnimationFrame: function requestAnimationFrame(func) {
if (typeof window === 'undefined') { // Provide fallback to setTimeout if window is undefined (e.g. in Node.js)
Browser.fakeRequestAnimationFrame(func);
} else {
...
}
We found, however, that we need to stub and mock many interfaces such as navigator, window, document and window.indexedDB. Many of these we addressed and now we get to the point where we're processing data loaded from the projectname.data, into several DataRequests:
new DataRequest(0, 64506, 0, 0).open('GET', '/data.unity3d');
new DataRequest(64506, 64527, 0, 0).open('GET', '/methods_pointedto_by_uievents.xml');
new DataRequest(64527, 64548, 0, 0).open('GET', '/preserved_derived_types.xml');
new DataRequest(64548, 1444752, 0, 0).open('GET', '/Il2CppData/Metadata/global-metadata.dat');
new DataRequest(1444752, 2940812, 0, 0).open('GET', '/Resources/unity_default_resources');
new DataRequest(2940812, 2968437, 0, 0).open('GET', '/Managed/mono/2.0/machine.config');
After this, we got stuck with abort() called in the memory allocation function _malloc. We're thinking this is due to the virtual memory overflowing. The error is probably not very helpful, but here it is regardless:

My question is: How can we enable support for running WebGL-generated builds into Node.js to use (or mold) this codebase for a potential back-end server?
