Well, tell me this. How is your keyboard supposed to know what player to kill if you just press a button? If you wanted to make a keybind to type /kill so you could provide a name, while useless, would look like this:
$remapDivision[$remapCount] = "Abusive Noob Commands";
$remapName[$remapCount] = "Kill";
$remapCmd[$remapCount++ - 1] = "openKill";
function openKill(%tog)
{
if(!%tog || !isObject(serverConnection)) //Checks if you're releasing the key or not connected to a server. If either are true:
return; //Don't continue.
newMessageHud.open("SAY");
NMH_Type.setValue("/kill ");
}
