rand^n generates a random number from 0 to N-1.

and you can have Lbl B and variable B and the program will have no issue

How to make border-line rectangles? I really need this.

You can use rectI() (inverted rectangle) to make all sorts of fun effects.  To make a white rectangle with black borders, simply draw a black rectangle and then an inverted one that is inside of it

Sweet, thanks.

Thanks a lot Builderboy, all this help has been wonderful.

I have a new question.

This isn't really an Axe question, this is more like problem solving.

I have a part of the screen where the main sprite can't enter (X>=78 and Y<=9). So, if X>=71 or Y<=9 all the getkeys should be disabled (71 cos the sprite is 7 pixels width).

I tried this:

If Y>=9 or (X<=71
//All getKeys code
End

However, when Y=9 or X=71, the sprite can't move.

So I though, when Y=9 and X=71, it can only walk left or down. It didn't work.

How can I only let the player move when (Y<=9 and X>=71) is false. I have to let the user move but not inside the forbidden area.

Thanks

You should use:

Code: [Select]

if getkey(keycode)                         
If x/y (any) != (max/min for x/y value)   ; choose the fitting one
x/y(any) +/-1 ->x/y                           ; idem
end


If getKey(1)
If X/Y != 71/9
X/Y +1 ->X/Y
End
I don't get the third line at all. What is +1/-1. Also, is there a way to make it global?

Thanks

This code works. I made and tested it myself 1 minute ago on your request
.SCROLLJP ;Scroll-Jump :P
0→X
20→Y
Repeat getkey(15)
ClrDraw
If getKey(2)
X+1→X    ;that cool arrow do you type with left-alt + 2 6
End
If getKey(3)
X-1→X
End
Pt-On(X,Y,[FF818181818181FF])
If X>88
Pt-On(X-96,Y,[FF818181818181FF])
End
If X=96
0→X
End
If X=666
Disp "The Game",imaginary i,"Never Gonna Give You up"   ; Could not resist xD
If X≤65535
Pt-On(X+96,Y,[FF818181818181FF])
End
If X=65528
88→X
End
DispGraph
End
Return
Just change the sprites to the ones you need.

Try to find the bug with "text(0,0,X>Dec.

I know how rand works more or less...

rand^n
.THIS GENERATES A RANDOM NUMBER UP TO N-1

So how to get numbers between n and m? I know we can do it with rand somehow, but can't remember how.

Think about it:

rand generates a number between 0 and 255.

Rand returns a 2 byte number i think,

Code: [Select]

Lbl RAN
    ...
    Returns a random number from r1 to r2, excluding r2.
    r3 is the increment.
    ...
    r2-r1/r3
    rand^
    *r3+r1
Return

I think that works?

You'll have to put the second argument to the ^ operator after it (the omission trick only works for the first argument of an operator)
rand^(r2-r1/r3)
