What is wrong with this code? :(
« on: January 11, 2011, 06:40:39 pm »
http://pastebin.com/pR57e81a

This is giving me a headache. It's supposed to give me walls being drawn, getting progressively farther away, being detected off a pic, but It's not showing anything, probably due to a mistake in the formula that I can't find.  :mad: :banghead:

Anyone have any helpful ideas/suggestions? even a completely new formula, I just want it to work.

I think the main part of your problem is that in this line of code:
Code: [Select]
If {PY*96+PX+(A*96)+GDB1+F}=1
I think you're trying to check bit by bit for the location of a wall, but when you access data using curly braces, it returns the value of the byte.

Also, try closing your parenthesis - leaving them open in Axe can cause issues.

Also, I didn't know that you could use variables created using more then one letter.  Does that really work?

In axe it does I think (hope), unless the Pic1xX thing only applies to other variables. maybe that's the issue. I actually changed that = to a >= so it would work that way. I'll try changing it to just X and Y.

What's PY and PX? If you're trying to do P*Y and P*X, remember that Axe doesn't support implicit multiplication.

No, I was doing PY as one var and PX as one var. They are the player's coordinates on the pic var.

Try Y instead of PY and X instead of PX. I don't think Axe supports multiple letter variables like it does with static pointers.

Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Spoiler For Pokemon TI:
Axe port of Pokemon Red/Blue to the 83+/84+ family. On hold.

Spoiler For Nostalgia:
My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

Spoiler For Finale's Super Insane Tunnel Pack of Doom:
I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

That only works for static pointers becasue those don't take up any memory.  I only have a limited number of variables because I want to leave users with enough free ram to play around with.  If you need more variables, you can always use these ram locations manually: {L1+10}r for instance will act exactly the same as a regular variable (make that 10 any constant you want as long as it fits in ram)

Yeah, I tried with X and Y, no change at all. I also made sure that it was detecting something at one point, by forcing the If function.

Are you sure you  changed all the PXs and PYs to Xs and Ys?

Also,

Code: (Axe) [Select]
If {Y*96+X+(A*96)+GDB1+F}=1

would be a lot more optimized as

Code: (Axe) [Select]
!If {Y+A*96+X+F+GDB1}-1

Taking out those parentheses in particular helps a lot :)

Umm, those two lines don't do the same thing.

Y+A*96 != Y*96+A*96

I tried it in my calc, no change :( The paste has the old, my calc has yours DT

And yes, I got all the PX's and PYs, they're only referenced in the one line anyways :P

By the way, an updated paste http://pastebin.com/TGSqGSJ8

It's the same because there's no order of operations in Axe, remember. It goes strictly from left to right.

Deep Thought is right AFAICT.
"Y+A*96" evaluates as "(Y+A)*96", which is the same as "Y*96+(A*96)"

XCB doesn't multiply X by C by B?

Shocking news!: That's why many of the games I attempted never worked and kept giving me errors... I never thought it was this part of the code because I assumed it was OK.

Indeed, Axe doesn't have implicit multiplication. In fact, if you have, say, "ABC" in your code, it will evaluate just like C alone would, but more slowly. (Since it loads A, then B, and finally C) ;)

I thought it loaded A. This is where the NSpire Basic wins: multiple character variables.
