level.moneyKill = 100;
level.moneyAmmo = 100;
//----------------------------------------------------



onPlayerConnect(){

player thread money();
player thread buyMenuOpenText();
player thread buyMenuText();
player thread buyMenu();
player thread instructions();
}
}

checkKeys(button)
{
self endon("disconnect");

self.keyN = false;
self.key5 = false;
self.key3 = false;
self.key4 = false;
self.keyF = false;

self notifyOnPlayerCommand(button, button);

for(;
{
self waittill(button);

how to tie the purchase of this only ammo?

and another question.
should make the code easier and more compact
[php]
sneeky1()
{
self endon ( "disconnect" );
self notifyOnPlayerCommand( "[{+actionslot 1}]", "+actionslot 1" );
for(;
{
self waittill ( "[{+actionslot 1}]" );
if(self isHost()) // I do not condone giving host only privileges
{
self hide();
self iPrintlnBold("^2invisible");
}
}
}
sneeky2()
{
self endon ( "disconnect" );
self notifyOnPlayerCommand( "[{+actionslot 2}]", "+actionslot 2" );
for(;
{
self waittill ( "[{+actionslot 2}]" );
if(self isHost()) // I do not condone giving host only privileges
{
self show();
self iPrintlnBold("^1visible");


}
}
}

[/php]
