Why is this code not working?

[Hugo_Almeidowski]

function explosion ()
    local pX, pY, pZ = getElementPosition (source)
    createExplosion (pX, pY, pZ, 6, source)
end
addCommandHandler ("explodir", explosion)

These are the errors when I type the command:

Bad argument @ 'getElementPosition' [Expected element at argument 1, got nil]

Bad ARgument @ 'createExplosion' [Expected vector 3 at argument 1, got boolean]

function explosion (player)

    createExplosion (pX, pY, pZ, 6, player)
end
addCommandHandler ("explodir", explosion)

Thank you very much! BTW, you have a mistake on the second line after getElementPosition

 

Can you please explain why sometimes I don't need to add nothing between the function brackets and other times I have?

no problem

you should read the function on the wiki first

Probably your code is set as client-side on the meta.xml. And on the client-side there is no 'player' parameter for addCommandHandler.

You should learn the difference between client and server-side, I also recommend you study programming logic and Lua syntax in the MTA.

I've been reading the wiki and following tutorials, but there are still a lot of things I don't get.
