Here's an example of code that should definitely not be written this way (it's very poor handwriting, resembling machine code):

gold=gold>0 and gold or 0

And here's how it should be written, making it both functional and readable:

TAX_GOLD = 10000
...
local playerGold = GetPlayerResource(PLAYER_1, GOLD)
if (playerGold > TAX_GOLD) then
	local newPlayerGold = playerGold - TAX_GOLD
	SetPlayerResource(PLAYER_1, GOLD, newPlayerGold)
else
	SetPlayerResource(PLAYER_1, GOLD, 0)
end
