Hello, I try to add a command to spawn an rhib at player's location. Here is the command I use "spawnat rhib ($player.x, $player.y, $player.z)".

But when player purchase this command the server console shows this:
Command 'spawnat rhib (236.9456, 2.104551, -1412.965)' not found.

And then I found that there is no "spawnat" command in the server console.  So I tried this command in the server console "spawn rhib (236.9456, 2.104551, -1412.965)" 

And it says:
look rotation viewing vector is zero
    spawned "rhib[59545312]" at (0.0, 0.0, 0.0)
spawned "rhib[59545312]" at (0.0, 0.0, 0.0)

So how to spawn enetity at player's location? Thanks for reply.

Some commands only work for the player running them, so a server trying to run a command like that would likely not work. You would most likely need a plugin that provides a server command to handle this, if there isn't one natively.

Is this still not possible? I see that the plugin offers vector3 now, but i cant figure out if i can spawn entities at designated coordinates

like: spawn minicopter ($player.x, $player.y, $player.z)

$player.x, $player.y, $player.z - Vector3 coordinates​
