I know I'm supposed to export the game in Cordova or something, and then put it in Intel XDK, however when i do this and try to emulate the game I just get a black screen. Alot of tutorials i've found are outdated or skip over alot of stuff so I have no idea what im doing wrong
Develop games in your browser. Powerful, performant & highly capable.
You might want to try the following 2 part tutorial:
Building with Cordova - PART 01 - Setting Up
Building with Cordova - PART 02 - Build an Android App
Looks involved, but will hopefully work for you.
It really is pretty easy. Export to Cordova into a folder somewhere on your computer, start new intel xdk project, import html5 code base, select the folder you exported to. Thats pretty much it to get it to emulate. Building isn't much more difficult.
