Help with movement.
« on: January 04, 2011, 08:01:06 pm »
So I decided to start learning axe, with my limited know how of the codes. I made a movement routine that ended up resetting my ram. Anyone have a movement routine that works and is not an unbreakable loop?

By movement, are you talking about simply moving around a sprite on the screen?

There's a thread around here talking about that...

edit: Here it is

Easy way to make a program not have an infinite loop:

First line of code (after description line)
repeat getKey(0) or getkey(15), for any key or for clear
your code
goes in
this area
end
that way, unless it actually crashes the calc, you can get out simply by pressing clear, or, any button if you used getkey(0)

Get used to that :P It'll probably happen a lot more before you learn how not to [purposefully] reset your calc.

On a related note, never do Asm(C7 unless something freaks out the OS and you have no other way of shutting down the calc.

What does Asm(C7 do? And is it done on the homescreen with Basic or Axe?

It's compiled with Axe (to RST $00) and it's basically a simulated RAM clear... with all of the fun [and data loss] of a real one.

Yep.

I used it to shut down my calc awhile back when some OS hook failed and disabled the 2nd+On combination on my calc. Pulling the batteries didn't work either, so it was the only option. Yes, Axe saved my calc  ;D

You could've done that in BASIC too: AsmPrgm: C7 then ran it from the homescreen with Asm()

Nice trick to know, although I personally just go in the MEM menu. I guess it can be useful if a normal reset or ON+DEL fails

You know, if you can't get to the ram clear menu or are unable to clear your ram for some reason where taking out the batteries doesn't work, you can always take out the backup battery (which powers the ram) to guarantee a ram clear even if the calculator wasn't frozen.

Here -- try this:
Code: [Select]
.TEST

[FFFFFFFFFFFFFFFF]->Pic1
10->X->Y

Repeat getKey(15)
  ClrDraw

  getKey(3)-getKey(2)+X->X
  getKey(1)-getKey(4)+Y->Y

  Pt-On(X,Y,Pic1)

  DispGraph
End

(Of course, when you're typing this out on your calc, you don't need to add the indents or spaces)

The code should display a solid black square that moves around with the arrow keys -- press [CLEAR] to exit the program.

For 1 minute, I assume, right? Because I removed all 5 batteries once, then immediately put them back, yet my RAM was still intact.

Hmm, that's weird.  Were you on the homescreen when you pulled the batteries?  Because pulling the batteries while on the home screen doesn't cause a RAM clear -- you have to be running a program or something.

Ok. thanks for that, Michael_Lee. I'm also learning axe, and am planning on a short game involving movement. this helped a bit on understanding the syntax in general.
