Is it even possible to output some values in text when programming?

[Lasomanos]

I have a script and want to check if it works correctly..
part of the code:

 local sacrifPos = {x=351, y=250, z=8, stackpos=255} 
local sacrifItem = getTileItemById(sacrifPos, 3966)
doPlayerSendTextMessage(cid, 22, sacrifItem)

same with this

if isPlayer(cid) then
doTransformItem(item.uid, item.itemid -1)

doSendAnimatedText(wallPos,"Crushhh",80)
doRemoveItem(getThingFromPos(wallPos).uid)
doPlayerSendTextMessage(cid, 22, isPlayer(cid))

It executed the condition (when I make it say "asd" it says asd) but when This, it doesnt say anything - empty message.
How to get output things from scripts? It would be really helpful. Thanks

why it doesnt say anything? Should it say something?thanks

doPlayerSendTextMessage(cid, 25, tostring(isPlayer(cid)))

why getThingfromPos returns me always different values, even tho nothing changed there?

17:45 table: 0x205f3130

Because it returns a table (array), and its memory address changes every time.
