It seams that your are calling into js somewhere? If yes if there is any error/exception in js that you call from UE4 it will result in a crash.
If you want more info you can build it from source and adding ‘-s ASSERTIONS=1’ where the HTML5 binary is build. Go to HTML5ToolChain.cs and add the line in GetSharedArguments_Global.
no, as far as I know, I should have the source code to do so. and I don’t have it. by the way same engine works good on empty projects or first person template, but when it comes to a heavy project it starts giving me errors. For source code downloading, I’m waiting for 4.9 to come.
by the way I have these errors at the bottom of html page:------>
Assertion failed: Typed arrays 2 must be run on a little-endian system
Assertion failed: Cannot call unknown function on_fatal (perhaps LLVM optimizations or closure removed it?)
I have the checked all my bluprints and widgets, there were two compiled bluprints, I have remove them, from the game. but I have received the exact same error. and I have create such function my self but there are several _on_fatal words in UE4Game.js and UE4Game-HTML5-Shipping.js files.
the original project was made in 4.7, and it had never give us an HTML output. Do you think it maybe because of the difference between versions!? I used to skip conversion before until the day that I have finally convert the whole project to 4.8.2(the version that we use nowadays). but nothing has changed!!! finally I have remove all the widgets and bluprints but nothing have changed either…
