Scrolling Tiles

[boriel]

Looks good, and very smooth...

It does indeed! :!:
The idea behind ZX Basic is you don't have to go down to ASM if possible :roll:

By the way:

Code:

if NextGraphic Band 64=64

can be shortened:

Code:

if NextGraphic & 64

That's right. In fact this rule can be applied to the other lines also
(band 32 = 32, band 16 = 16 etc).
Slenkar, the rule is

Code:

IF x band 2^n = 2^n THEN

can be replaced by

Code:

IF x bAND 2^n THEN

Not sure if the compiler already optimizes that with -O3. Will check it... :|
