[Scripting] When to put "( )"

[dabaflow]

function skinMonster(cid,item,skin)
	local random = math.random(1,8)
	if(random == 1) then
		doPlayerAddItem(cid,skin,1)
		doSendMagicEffect(getThingPos(item.uid), CONST_ME_MAGIC_RED)
	else
		doSendMagicEffect(getThingPos(item.uid), CONST_ME_POFF)
	end
	doTransformItem(item.uid,item.itemid+1)
end

I want to know how to know when to put the ( and ) 's.

Like in the code above "if(random == 1) then.

Why do you have to write "(random == 1)?

I think a "gramma" tutorial for LUA would be nice xD

EDIT; And please try to not answer in a very advanced English(CIP language).

lol?, there is no needed omg... is needed sometimes but no in that script, maybe who made that script is used to write c++ codes o.o

Parantheses are basically just added to help you organise your code.

Formula Example:
( ( $level * 3 ) / 10 ) - 40

IF Example:
if isPlayer(cid) == TRUE and ( getPlayerLevel(cid) == 100 or getPlayerLevel(cid) == 200 ) then

So it is not necessary?

In most cases? No not really. Although it is required when using certain functions (to enter parameters etc).
