i am having trouble. my character goes out of the screen. how do i make a barrier on the outside edge (x=0, y=0 through 88) and then (x=0 through 88, y=0) just the outside pixels.

 
 rem * i like trains
 lives = 128
 dim lives_centered = 1
 dim lives_compact = 1 
 set romsize 4k

Skip adjustments if out-of-bounds. Example:

if joy0up && player0y > 0 then player0y = player0y - 1: goto jump

The subtraction does not happen if already at the lowest amount allowed (0 in this case).

You'd change the existing lines that say "if joy0up" or "if joy0down" and so on. Each of those existing lines would be modified to include the additional checking. As far as *what* additional checking needs to be added, it depends on which direction you're going in and which variable you're changing-- that is, whether you're updating player0x or player0y, and whether you're incrementing it or decrementing it. You want to be sure you don't decrement them past 0, and you want to be sure you don't increment them past the edge of the screen-- 159 for player0x, and I think something like 80 or 88 for player0y.

I added this to your program based on what has already been posted:

   if joy0up && player0y > 19 then player0y = player0y-1: goto jump
   if joy0down && player0y < 89 then player0y = player0y+1: goto jump
   if joy0left && player0x > 1 then player0x = player0x-1: goto jump
   if joy0right && player0x < 154 then player0x = player0x+1: goto jump

Very nice start! That enemy sure does lock on to you FAST though!

..and, I'm not sure if I should mention this, but, it looks like your player gets *really* flaccid (right down to his legs!) just before his "missile" detaches itself and unloads onto the enemy.. *cough* Maybe it's just me..

I'd personally start the players, er, "rogue spear" higher up to avoid firing up overactive imaginations

Maybe you could start the missile just above the players head so it looks like a laser beam.

ive noticed that, and ive tried to experiment and said "maybe i could make a new custers revenge" so every time his "missile" shot it left a little suprise underneath him lol but i took it out cus i was just messing around with the "ball" script.

[esplonky]

so i was messing around with my code and i made my playfield this

 playfield:
 ................................
 .............XX.................
 .............XX.................
 .............XX.................
 .............XX.................
 .............XX.................
 ...........XX..XX...............
 ...........XX..XX...............
 ................................
 ................................
 ................................
end

that would cause major uproar.
