Error 'calling on bad self'

[Linkpy]

Hello !

I've got a little problem, and I don't know how to resolve it...
I'm making a GUI for a music player (yes, a music player with Löve ) and I'm working on the base class 'component'. A component has got a position ( X, Y ) and a size ( W, H ) and I use some linear interpolation for animation. So, to have the X position, I need to use component:get_x function. But, for component:get_y and component:get_h, I've got this error :

Code: Select all

Error: main.lua:12: calling 'get_y' on bad self (number expected, got nil)
stack traceback:
	[C]: in function 'get_y'
	main.lua:12: in function 'load'
	[string "boot.lua"]:407: in function <[string "boot.lua"]:399>
	[C]: in function 'xpcall'

And I don't know why I got that... I've tryed to change get_y to getY, but I got the same error... If someone can help me, there are all the code : https://github.com/linkpy/simple-player .

Thanks for your answers

Did you call the method like component:get_y()? it looks like you forgot the : and instead did component.get_y().

I ckecked it, but this not the problem because :

Code: Select all

component.get_y (component)

Doesn't work too...

So the error location is actually masked because of all the tail calls you're doing, which makes this considerably harder to debug, but the error message seems related to ffi.metatype, or the ffi in general.
