Making a library, not quite there yet [HitBoxes]

[LuaCre]

Hey, I need help, I have this library for object collision, right now it makes Boxes with a function
Boxes have these properties

x = x position
x2 = max X position (x + width)

same with y,

and v, what the object is "Grass" , "Barrier"

I have a function that tries to return if 2 boxes are colliding, but it doesnt seem to work properly, please help?
(Function name playerColliding I think)
