My HTML5 build gives errors in Chrome and Firefox

I have managed to get the HTML5 build built. However in Chrome it is reporting “Too many variables declared” and in Firefox it is throwing an out of memory error.

Maybe you have a memory leak in your code?

I was testing with the SwingNinja sample.

Hi JKnife,

Thank you for letting us know about your issue. Currently Chrome is not fully supported, but Firefox should be able to run the engine if you are using the 64 bit Nightly edition. There are more fixes that will be coming out in the future for the HTML5 build.

Have a great night!

Solo puedo compilar para html5 si compilo el source?

Lo sentimos, utilizando traductor de google

Si. Primero tiene que instalargithub.com/kripken/emscripten/wiki/Emscripten-SDK continuación, ejecute la secuencia de comandos de generar proyectos. En Visual ahora verá una opción para construir la plataforma HTML5

Muchas gracias :smiley:

I can take steps to create a pack of html5? I already have the Emscripten-SDK and run the _internal.bat

I used the UnrealFrontend (built from source)

10

not built UnrealFrontend ???

11

Ya compile el UnrealFrontend y nada, cuando lo compilo me ejecuta el firefox pero sale como si no existiera ningún archivo creado.

12

qué versión de Firefox está usando? ¿Has actualizado a la edición nocturna de 64 bits?

Already have the Emscripten-SDK and run the _internal.bat

Al parecer no me genera el UE4Game.js ni los html, :frowning:
