Hi!
I often write that, if I want to move a sprite, that can't leave the screen (you know what I mean?):
If getKey(1) and ({38+L1}^r≠48)
{38+L1}^r++
ElseIf getKey(4) and ({38+L1}^r≠0)
{38+L1}^r--
End
If getKey(2) and ({36+L1}^r≠0)
{36+L1}^r--
ElseIf getKey(3) and ({36+L1}^r≠63)
{36+L1}^r++
End(It's for a 16*32 sprite
)
x position: {36+L1}^r
y position: {38+L1}^r
But this code looks very unoptimized...
Do you know a more optimzed code to do the same?
Can you explain, how it works, too?
Thanks
BTW: I searched for the "≠" a long time
