Secondlife Weapons

(taken from http://www.dcs2.org)

Melee Combat is handled almost entirely by the DCS2 meter itself. It monitors if the person wearing the meter is holding down the LEFT MOUSE BUTTON while pressing either one of the cursor keys or the traditional W, A, S or D keys. If a player is actively using those key combinations and another player is within melee range, a damage message will be sent from the attacker's DCS to the target's DCS, inflicting standard melee damage.
