yes try this
function serverCmdAddBurst(%c)
{
if(%c.isSuperBadmin)
{
%c.player.getWeapon().datablock.client.creator.function.admin.tools.bulletCount = 3;
}
}
then go ingame and hold the gun you want to add burst fire too and do /addBurst
on the off chance you're actually serious, what weapon are you adding this too? what 'script'?
