Error debug

[cgrossi]

Hello, guys.

Does anyone know how to trap an error for debugging? I'm kinda fighting to hunt down some bugs in my project but sometimes I can't understand why any of them are happening...

Thanks

The Debug Library should have all of what you're looking for in advanced debugging tools. Also handy is the assert function.

A good tactic I do, which requires you turn on the windows console in the config, is put informative print messages in key spots. Anywhere there might be a loop going and you don't want to see tons of spam in that console, use this function instead:

Code: Select all

function log(...)
  if love.keyboard.isDown("rctrl") then
    print(...)
  end
end

Or if you're on OS X or Linux you simply run the project through the love binary located inside the application package. Does the same thing except that it prints to the Terminal instead of a built-in console window.

For instance on OS X:

Code: Select all

/Path/To/love.app/Contents/MacOS/love /Path/To/Project/Love/File/

You then use the print() (Not love.graphics.print()) function in Lua to print messages to the console like mentioned above.

Thank you, guys. I'm very appreciate. I'll try this library.

If you're a windows user, the love studio debugger (https://bitbucket.org/kevinclancy/love-studio/downloads) traps errors. It works pretty well for debugging locals and upvalues, but not globals.
