Spent around 2 hours attempting to setup Unreal Hx with UE4 4.19.2 #101

As title says, had no joy, engine would not recognise the plugin, definitely in the correct place.

Really enthusiastic about using Haxe with UE4 but alas, no luck.

Followed the instructions, word for word on the readme.

Do you have Haxe 3.4.7 / 4.0, hxcs and hxcpp installed?

Did you try the following : -Create a empty c++ project in the launcher -Create a plugins/Unrealhx folder -Copy the repo to the plugins UnrealHx folder -Add the plugin "UnrealHx" to the .uproject file in a text editor -Edit the build.cs file under source/projectname to extend HaxeModuleRules instead of ModuleRules -Open visual studio and compile

It should be OK, haxe libs and UE4 should compile and launch.

What kind of error do you get?

-Add the plugin "UnrealHx" to the .uproject file in a text editor.

Missed this step, will check back after trying.

Thanks for the prompt reply!
