error while learning lua

[cassius]

I added this code to main lua and got error message on first line which read 

'=' expected near  ' '

anyone help?

 

local sound = Sound:Load("Sound/Music/gametune.wav")       
source = Source:Create()
source:SetSound(sound)
sound:Release()
source:SetLoopMode(true)
source:Play()

Can you show your entire main.lua?

Can you add the code via a code tag? It is really difficult to read this way.

Not sure if it is the issue but you can make 'source' a local value.

local source = Source:Create()

If your remove your sound code, does the error still appear? Your main menu seems fine further. Any chance you modified the menu.lua?

[cassius]

Game runs fine with sound code removed. I have not touched menu. lua. I got the sound code directly from api reference, its not my code.

[cassius]

Got it working. I copied some sound code from a c+= project of mine inoi main.lua and translated it to lua code and it worked. I left out sorce release line as that was not in my c++ code. Thanks for answers.
