LOL, sorry, I did put warning message in bold.
The reason being trying to find out how to setup a working multiplayer blueprint kinda needs to read those native code a bit.
And since I already put sometime into finding relevant info, I also want to keep it in one place in this thread so in the future I can refer back to it.
I can already see myself rolling the controls pretty soon and hopefully can give you guys a movement replicated Pawn blueprint so people can happily do extend it.
The good thing about this is that 's project is the empty blueprint project, thus as of now it has no asset dependency except that arrowMesh.
So any blueprint derived from this project can be copied to other project and start to work, just need to replace arrow into something available with engine would do the job.
