Hi ! First all, THANKS VERY MUCH for your ANSWERS. I like this community. So, I'm very novice compared to you. I'm trying to recapitulate to clear. I said: [ 2 ] I want, also, some way to build audio game engine tools, but Unreal4 or Unity 3D isn't work on linux at now, some suggest for my frustation ??? ​You said: ​"...PortAudio and libsndfile are the only dependencies for YSE now, and they are both supported on linux. If anyone wants to create the neccesary build files... ...YSE Sound Engine..." ​"I'm not a game developer, but Unity 3D installed on my system and ran a version of the the Roll-A-Ball tutorial that I modified so that it would send OSC messages... This is my first attempt at running an Arch system, and my wee experiment is about two months old. I'm still a novice with Arch, and pretty much a novice with Unity 3D. So, when you say it isn't working, your requirements might be much greater than mine, but it is working "well enough" to get me started." "...noted Unity does have a linux build, I've used it to make a demostration game at work..." ​ ​"...though I'd rather see more work be put toward the open source Godot engine..."​ ​ "As far as I know the Unity3D does work on Linux nowadays. Doesn't mean I recommend it in any way though. I really don't know what it is you are after, so it's hard to help."​ "I'm not a game developer, but Unity 3D installed on my system and ran a version of the the Roll-A-Ball tutorial that I modified so that it would send OSC messages...

"...godot already has a fairly sophisticated audio features..." ​-------------------------Me again--------------------------------- I didn't met godotengine yet, Thanks. Already I need to testing better that alternatives.​ ----------------------------------------------------------------------- So, please, give some time to improve my self and test this alternatives because now I'm only *exploring* alternatives. If anyone want to help me, you are welcome, but I believe that is better do it by private messaging for don't dirty this forum because I'm answering because I prefer it than the silence. ​ Thanks very much, Juan.​ BioSoundSystems.com
