Playable demo time !

I won't post any screenshots 'cos I won't resolved the levels for you ^^ (even they are really simple)

You can download it here : http://mattias.refeyton.fr/espace-ti/gravityWalls/GRAVWALL.8xp

I nearly finished the level editor, so you'll see it soon

But you have to do a loop, since it only scroll one byte out ot 8 ... so you have to do a For loop in Axe, which adds several bytes to the compiled program, when a simple DJNZ statement adds only 3 bytes. My Axiom is still faster and lighter

Since this is just one ASM command repeated, it's way faster than Axe code, which use a lot of routines for it

Of course you can, but it'll be slow since you can't use bit rotations and shift (what my ASM code does).

My ASM code will be faster than every Axe routine you can do for scrolling sprite, I recommend you to use it instead of doing the same thing in Axe, which will be heavier and slower.

Also : now I have the collisions working !



Next, I'll implement the arrows, and it'll be them which change the gravity. I'll also add a door in order to have a fully functional first level

EDIT : I joined the Axiom in *.8xv format.

Whoaaa They are beautiful ! Thank you a lot !

May we take a look at it's source? THat could be VERY useful!

Of course

Scrolls the content of Pic1 one pixel in the given direction and re-stores it to Pic1

Eeeeeer no I'm not but it's right that I took the character from Graviter and Portal X.
