void syncVar(string variableName)

Syncs a variable to all players.

// global variable outside all functions
bool someVar = false;

void onWorldStart()
{
    // if server or single player
    if(isServer())
    {
        someVar = true;
        syncVar("someVar");
    }
}

The variable must be a global variable, which is defined outside of any functions.
The variable must be a float, int, bool, string or vector2, other types cannot be synced.
Synced variables are synced to players who join mid-game.
Variables can be synced at any time by any player.
In singleplayer, the function has no effect.

netExec

void netExec(int destPlayerID, string codeString)

Execute a string of code on a remote computer.

// display message on all computers (includes local computer)
netExec(NET_EXEC_DEST_ALL, "print(\"Hello All!\");");

// display message on clients only
netExec(NET_EXEC_DEST_ALL_CLIENTS, "print(\"Hello Clients!\");");

// display message on server only
netExec(NET_EXEC_DEST_SERVER, "print(\"Hello Server!\");");

// display message on a specific computer
int destPlayerID = getServerPlayer();
netExec(destPlayerID, "print(\"Hello player ID " + destPlayerID + "!\");");

The netExec function is disabled by default for security reasons, use setNetExecEnabled to enable.
netExec can be used from any computer (server or clients can exec code anywhere else).

getNetExecEnabled setNetExecEnabled

bool getNetExecEnabled()

Get netExec function enabled status.

print("netExec enabled: " + getNetExecEnabled());

Always returns false in single player.

setNetExecEnabled netExec

void setNetExecEnabled(bool enable)

Enable netExec function on all computers (server only).

void onWorldStart()
{
    if(isMultiplayerServer())
    {
        // enable netExec globally
        setNetExecEnabled(true);
    }
}

Has no effect in single player.
