worldx(x,y) and worldy(x,y) ?
 

Can someone please explain what worldx(x,y) and worldy(x,y) do and how they are used?

EDIT:
Thanks Velox Cruentus, I get it now.

It converts screen coordinates to level coordinates.
Like screenx(x,y) and screeny(x,y), but opposite.

Alright...

screenx( mousex, mousey );

Basically, You have your screen width/height, and the level width height.
The function changes the level location to the same point on your screen. It's like... If you're trying to go from layer 3 to layer 4. Layer 4 is using screen location, and Layer 3 is using level location.

It does the opposite. It converts screen to level.

ya. i think i get it now

( For those who want to go on with this... )

Why exactly did you post this, when someone already said:

?

He had not understood it beforehand. Thus, to clarify, I showed that he did understand, rather then just let other people explain. The two functions are pretty similar; if he didn't know one, the likelihood he didn't know the other is higher.
