Shop system tfs v2 for tibia 7.6

[danick10]

Hello, I'currently working on a retro tibia server 7.6 with a downgraded version of tfs. I think it's the version 0.3 and i've used gesior aac. I've made many change to this acc to works fine for this version of tfs and now the shop system is perfectly working. I've used a global event script to deliver the items and I cant find out the issue. Here is the bug:


local result_plr = db.getResult("SELECT * FROM z_ots_comunication WHERE `type` = 'LOGIN';")

cid = getCreatureByName(tostring(result_plr:getDataString("name")))
if isPlayer(cid) == TRUE then

And in the console it says : Attempt to call global 'getCreatureByName' a nil value:

Can someone explain me how to solve it please

try using

cid = getCreatureName(tostring(result_plr:getDataString("name")))

It says Creature not found :/ but thx for the functions

When ever I am checking the value I am retrieving from a function I break down the steps of the function call.

So what I would use to check the values is a simple print function which would print the results if any in the console
Example:

print( result_plr:getDataString("name") )
print( tostring( result_plr:getDataString("name") ) ) -- to string is possibly not needed but I will use it anyway
print(getCreatureName(tostring(result_plr:getDataString("name"))))
cid = getCreatureName(tostring(result_plr:getDataString("name")))
print( isPlayer(cid) )

This method of testing values allows me to see what values are being passed so I can handle them accordingly

Mmh I do not understand your method of testing, I've created a global event with your code and it says : Error global event on think

There is no need to create a global event, a print function is part of the lua language and can be used anywhere in your scripts, maybe you should focus more on learning lua rather than editing code.

I only say this because this will help you better understand the scripts you are writing or editing.
