Thank you TB Jokers, this saved me a lot of time and thought. I have made it work with my mod built over Ineisis:

AI.es that goes in the client

This goes in your Game.es where you handle messages coming from the server:
Code:
case CS_MOVE_PLAYER:
{
SockAddr addr; Vec positiontomoveto; // sockaddrnotreally needed
ClientRecvMovePlayer(Server.data, addr, positiontomoveto); positiontomoveto.y += 5.0; if(Plr.isneph)positiontomoveto.y += 15.0;
Plr.pos(positiontomoveto);
} break;
case CS_AI_SPAWN:
{
CM.New("Recieved CS_AI_SPAWN");
//File f = Server.data;
Str name = Server.data.getStr(); Str obj = Server.data.getStr(); Int id = Server.data.decIntV(); Flt x = Server.data.decFlt3cm(); Flt z = Server.data.decFlt3cm();ai.New().spawn(name,obj,id,Vec(x,0,z));
} break;
case CS_AI_MOVE:
{
CM.New("Recieved CS_AI_MOVE");
Int id = Server.data.decIntV(); Flt x = Server.data.decFlt3cm(); Flt z = Server.data.decFlt3cm(); Int ith; REPA(ai)if(ai[i].ID == id)ith =i; ai[ith].Move(Vec(x,0,z));
} break;
case CS_AI_ACTION:
{
//CM.New("Recieved CS_AI_ACTION");
} break;
Put this right after you call if(Plr)Plr.update(); on the client
Code:
FREPAO(ai) .update();
Put this after REPA(NeighborClients)NeighborClients.lockedData(i).drawText(); on the client:
Code:
FREPAO(ai).drawName();
In your RenderGame() function on the client make sure oyu have this:
Code:
case RM_PREPARE: if(Plr)Plr.drawPrepare(); REPA(NeighborClients)NeighborClients.lockedData(i).drawPrepare(); FREPAO(ai).drawPrepare(); break;
Put this in Main.es on the server Init() function:
Code:
REP(20)ai.New().createAI(i,"Warrior","Obj/Chr/Warrior/0.obj",Vec(RandomF(0,20),RandomF(0,20),RandomF(0,20)),10);
add these enums to your commands.es
Code:
CS_AI_SPAWN ,
CS_AI_MOVE ,
CS_AI_ACTION ,
Also I have removed the ignoring physics collisions between Players/AI see my work around here:
