is D your previous getKey? and it flickers because (a) you don't erase the pic after updating the screen and (b) when you do press a key, it's not going to draw anything that loop because getKey won't = 0, so itll skip drawing the sprite. Does that make sense?

Hmm well you don't need to do ClrDraw, you can just do "Pt-Off(X,Y,Pic#" before you update it's X or Y location, and then draw the new sprite.

The problem is, it might have been a completely different sprite, and then it would only erase a portion of the sprite. Of course, I might be wrong. Does it slow the program down?
Also, that doesn't help me for making the sprites not flicker.

Pt-Off doesn't work that way. What it actually does is similar to the "overwrite" option in xLib. You could do Pt-Off with a blank sprite to erase though, I think

Would I need to append a 0000000000000000 to a hex code, or is that the default?
Also, I'd really like some help with the flicker problem...

Umm, I might be able to help with the rest of the code if i actually knew what it did other than display sprites when you press keys.  I can't really get intentions from code. :P

You need a beeline or a ':' between the ) and the End, and you don't need the )

also for any If statements, any time you use and/or/xor you need a bracket after.
So this: If x=10 and x=11 would change to this: if x=10 and (x=11
that's just some quirks of the axe parser right now.

Edit: wow, didn't see those new posts x.x

Okay. It displays a sprite and moves it around the screen when you press the corresponding arrow key. The sprite that's shown is part of that direction's walking animation. A  X is constantly changing values from 0 to 20, and that value changes which sprite in the walking animation is shown. The problem is the revert-to-non-walking-sprite. This causes the walking animation to constantly flicker back to the default non-walking sprite, when it should be displaying a sprite of a limb extended.

The fact I can make a sprite animate and walk around, though, is awesome, because I haven't been able to do this is pure basic in my two years of (amateurish) programming. I learn how to do this in 2 days with Axe parser. Cool stuff.

So the first sprite is the walking down animation, the second walking right animation etc. is that correct? if so what are you using for standing still?

The standing still sprite is the first and third hexadecimal code in each Pic#. I can add walking-specific sprites later.

Lbl FN
I think that should do what you want... if it doesn't just tell me what happened, scince i just typed this up w/o testing it :P  Ask if you want to know anything about that, of if really just want me to try to edit yours...

EDIT: Forgot to initialize the variables! oops :P
EDIT2: Hopefully you didn't try that code either, you wouldn't have been able to quit...

try changing the If K=15:Goto FN:End to ReturnIf K=15 and get rid of the Lbl FN at the end as well as the Return. You could also change the While 1 to Repeat K=15 or Repeat getkey(15), and then adding a Return at the end of the loop.

btw, ikemike, i swapped the numbers of the left and right directional sprite so they directly correlate to the arrow keys

I tried the code, but it gives me a fatal error... Then I have to take the batteries out and it resets the RAM.
