Dear all,
I'm trying to get my head around functions (in general, not just _init, _update & _draw) and I'm looking at the platform tutorial, PicoJump, in issue 2 of the fanzine. There's a function named CANFALL() that I'm having a problem with deciphering...
FUNCTION CANFALL() V=MGET(FLR((PX+4)/8),FLR((PY+8)/8)) RETURN NOT FGET (V,0) END |
I understand the MGET line and how it's placing the value of the tile underneath the player into to the variable 'V'; however, I don't understand the line:
RETURN NOT FGET (V,0) |
I can't work out if it's returning true or false based on sprite V!
Any pointers for a layman like me?
Many thanks.
T.
