I meant someone actually makes it and sends it to me. But I can try myself.
if player = <playername.skin>
when <button = custom1> is pressed
change player.charability
if player.mo and player.mo.skin = "skinname"
and player.cmd.buttons & BT_CUSTOM1
player.charability = CA_AIRDRILL
else
player.charability = skins["skinname"].ability
end
Sorry, neither way works for me.
