Annnddddd.... I DID IT !!! I accomplished connecting Pharo with Unreal so I can script it with Pharo. It works from inside the editor and for the game as standalone. True live coding :) I am amazed how fast it is, but then I guess it should be expected with shared memory. You can watch a short demo here https://www.youtube.com/watch?v=6fsUKW8-bBE&feature=youtu.be When I first created the loop, nothing happened. So naturally I expected that my CPPBridge was not working, my loop is basically going from 1 to 150 (z axis), 10 times. After inserting a delay of just 10 milliseconds I could see movement. So apparently without the delay Pharo , Unreal and CPPBridge are so fast that do 10 times movement of 1 to 150 in under one frame !!!!! So now I will have to slow down thing to make them work as I want !!! LOL!!!! I expected to be fast but nowhere that fast. Not that I am complaining. But this is just the first step, now I will slowly and steadily start to wrap Unreal Engine 4.13 API for Pharo. Its a dream to use Pharo professionally :)
