[LUA] Creating some easy scripts

[Zippow]

This is some useful functions

<-- function onSay(cid, words, param) -->

<-- function onUse(cid, item, frompos, item2, topos) -->

<-- function onStepIn(cid, item, position, fromPosition) -->

<-- function onCastSpell(cid, var) -->

<-- Let's start off with creating a command to buy a rune -->

function onSay(cid, words, param)

local cost = 10000 <-- enter the number of gps the rune should cost -->
local charges = 10000 <-- write on how many charges you should get -->

  if doPlayerRemoveMoney(cid, cost) == TRUE then
    doPlayerAddItem(cid, item id, charges)
doPlayerSendTextMessage,cid,22,"You bought a rune"

else
doPlayerSendTextMessage(cid,22,"Not Enough Money"
 end
 return TRUE
end

<-- Let's make a reward by clicking a switch -->

function onUse(cid, item, frompos, item2, topos)

if doPlayerAddItem(cid, 2150, 1) == TRUE then 
 doPlayerSendTextMessage(cid,22,"You earned a reward"
 end
 return TRUE
end

<-- Let's make a EXP tile -- >

function onStepIn(cid, item, position, fromPosition)

if doPlayerAddExp(cid, 22) TRUE then <-- You can change the EXP amount -->
 doPlayerSendTextMessage(cid,22,"You walked on a tile, 22 exp earned") 
 doSendMagicEffect(getPlayerPosition(cid), 31)
 end
 return TRUE
end

<-- Let's make a EXP tile -- >

Code:
function onStepIn(cid, item, position, fromPosition) if doPlayerAddExp(cid, 22) TRUE then <-- You can change the EXP amount --> doPlayerSendTextMessage(cid,22,"You walked on a tile, 22 exp earned") doSendMagicEffect(getPlayerPosition(cid), 31) end return TRUE end


Does not work for my 0.3.7.

It explain me some Errors like "Unenspectet symbol near "=".

Change
if doPlayerAddExp(cid, 22) TRUE then <-- You can change the EXP amount -->
to
if doPlayerAddExp(cid, 22) == TRUE then <-- You can change the EXP amount -->
He forgot the double "=="

This is not even tutorials, not even close to tutorial. You have not even coverd the simple things such as if, elseif, else, then and etc...

When i started to learn lua, i started with this thread very useful: http://otland.net/threads/scripting-guide.74030/

 

[WibbenZ]

Change
if doPlayerAddExp(cid, 22) TRUE then <-- You can change the EXP amount -->
to
if doPlayerAddExp(cid, 22) == TRUE then <-- You can change the EXP amount -->
He forgot the double "=="

true =  if(doPlayerAddExp(cid, 22)) then
false = if(not doPlayerAddExp(cid, 22)) then

...

And is it only me who noticed the pr0 tabbing?

if then
          do that

        doPlayerSendTextMessage(cid, 22, "You earned a reward"
    end
return true
end

function onStepIn(cid, item, position, fromPosition)
local exp = 22, -- You can change the EXP amount
    if(doPlayerAddExp(cid, exp)) then
        doPlayerSendTextMessage(cid, 22, "You walked on a tile, ".. exp .." exp earned")
