A little help
« on: April 07, 2010, 12:07:25 pm »
I am redesigning my Pokemon battle simulator, using Axe. So I have a few questions.

1. How do I use commands like GridOff and AxesOff in Axe.

2. Once I create an AppVar, how do I store data into it? And how do I recall data from it?

3. And are screen parameter vars, like Xmax supported?

And I may have more as I go on.

I haven't messed with 2, but for 1 and 3, you don't need to change Windows settings at all. Axe doesn't use them to draw graphics. Everything is pixel by pixel. Like when using xLIB, you would just need to erase the graph buffer then update the LCD content through Axe commands.

ClrDraw
DispGraph

Ok. Fair enough. And what about text commands. If I wanted to display simple text on the homescreen, how would i do it.

I'm pretty sure this info is in the Axe documentation

I didnt understand it, but never mind.





What about storing and recalling to and from appvars. The documentation tells u how to create/remove/select/ and archive/dearchive but i dont believe how to actually store data to them.

And I'm having problems: here is my test code.

ClrHome
Fix 4
Output(1,1,POKEMON
Pause 1000

When I compile this, it displays nothing.

I'm not too sure if Output can be used this way. If I remember, you had to store the text to a pointer like Str1 then do Output(1,1,Str1. Also I am not sure if Fix works with Output. I think it was just Text (graph screen).

Can an Axe Parser program archive itself?

Yes.  Technically, it is not running the actual program, but a copy of the actual program, so you can archive it.  You just need assembly routines.

Now, I am trying to test for the presence of the program's storing appvar (POKE). Now, the documentation says GetCalc() returns 0 if not found OR Archived. How do I determine which so the program can enter install if not found, or just unarchive if archived.

And how do I store data to the appvar and recall it later.

After you select the name of the appvar, immediately unarchive it.  Then, when you try to do getCalc() you're sure that if it existed, its definitely in RAM and so it only returns 0 if it doesn't exist.

To write data, you have to store the pointer that is returned by getCalc() either into a variable or in RAM.  Then you read and write to that location as if it were any other RAM location.  The same way you would do 100->{L1+6}  You can do 100->{A+6} if you stored the appvar pointer to A.

Thank you. So much. I was having a migraine. But, if I run unarchive on an Appvar, it wont throw an error if it doesnt exist?

Nope.  Just nothing happens.

Oh wait a minute!  I forgot to document that!  The Archive/Unarchive command returns 1 if it actually performed an unarchive/archive and 0 otherwise.

Ok. Cool. I should be pretty set now, outside of a few questions about sprites:

Is it possible to do a larger than an 8x8 sprite, using the current commands?

And, if I need to write data to a memory location where the integer is larger than 255, it gets more complex. What is the procedure for that?

Edit: And What are the getKey codes Axe uses.

I assume to do this Axe uses some of the hidden 8 KB of RAM on the 83+, right? (The calc has 32 KB of RAM but only 24 is avaliable to the user)

I believe to do anything larger than 8x8 sprites (up to 16x16, I think) you have to use routines which there is one provided by Quigibo and one other person who's name escapes me, I'll find those in a second. But I'm fairly sure there is no command supporting larger than 8x8 (I may be wrong though).

As for the getKey commands, I'm pretty sure they are the same as xLib. DJ posted something I think, I'll find that too.

Ok, so I searched and found the two routines showing how to display larger sprites (Up to 16x16, I think. I don't know exactly the size limit) by Quigibo here and LordConiupiter here (the post that actually shows it though this one that DJ posted; LordConiupiter's post just provides the download)

In regards of the getKey commands. I was correct in saying they are the same as xLib. Here is the post DJ made about them.
