Hey guys! Just thought I'd bring you all up to speed on one of my unannounced projects.

Codex 2 has been in development now for the last few months. Progress has been slow mind you do to a heavy workload and very high stress levels.

So far I have rewritten all of the original Codex to make it even faster and so that incorporates almost all of the old commands. Here's where you guys come in!

I need some constructive input on one of the features I'm adding into Codex 2.0

Codex 2.0 is taking a step away from the painstakingly slow sprite method I used before and will come with it's own tile map editor and tile editor. The editors will be able to be removed from the calc once they are no longer needed to edit your maps.

This in turn means the ability to display your maps in an instant, and a quick and user friendly way to edit your maps/tiles.

What I need from you guys.

1) What is the most appropriate tile size. 8x8, 16x16?(choosing a standard will make the program size smaller.

2) What would be the most appropriate command syntax as you will need to supply the tilemap and tileset to display.

3) How do I make it so that you are still able to do hit detection.

I haven't done any basic in like 3 years so I need some input from you basic programmers.

  1. My choice is 88 pixels. The other option would only allow a 46 grid of characters. Sad
  2. Could the syntax be any built-in token or function followed by custom arguments? What I'm thinking is to be able to use the [font="courier new"]T token (for tile, perhaps), which would never realistically appear after a new line otherwise, making that part of the rendering easy. I think it would be a good choice:
    Quote:
    [font="courier new"]:ClrDraw
    :T16,24,A,
    :T18,26,B,

  3. The cheapest way to do hit detection is with [font="courier new"]pxl-Test(), so make sure you leave that an option as it would be useful to all of us. Other possibilities involve reading the elements in strings, lists, matrices, and so forth, given the positions expressed by other variables. But, as the method is dynamic in itself, I don't think Assembly would offer that much more assistance in this regard. I could be completely mistaken. :biggrin:
I may be entirely off-track with these concepts. Could you explain your needs in more detail? Smile

For tilemaps, I like using Matrices for doing hit detection, although they get rather large.....have something like that so a user can get the number of the sprite/tile at a given location in the map.


do not use real() for sending commands, this is one of the things that ticks me off the most with xLib is that it interferes w/ Omnicalc and Symbolic. I liked the syntax from Codex 1. however if you are making it an application pick a different command to intercept.


perhaps allow the user to specify dimensions in a multiple of 8.....otherwise use 8*8 as the standard

The size thing is pretty straight forward.

As for the syntax, this will still be an assembly program therefore I will still use Ans as the input as before. In order to display your tilemap I was thinking of something along the lines of.

:"D.Map.Tileset
:Asm(prgmCODEX2

The reason being is you would be able to create a full screen tilemap using a select tileset with the editor.

As for hit detection.

The reason I ask this is the above mentioned method would make it hard to detect if the tile you're walking towards can be walked over or not, as the tilesets and maps would be stored as appvars so as to save alot of space that is wasted by matrices and lists.

Pxl-Test( only works well if you know you cant walk into pixels, but if you test a matrix, you can find a numbers position in a string using sub and test if it is walkonable or not by something like


Code:
:"Tilemap.NUMOFTILEAT.{1,10
:"Asm(prgmCODEX
:Ans->A
:If sub(Str1,A,1)=W
:Then
:Disp "walkonable
:Else
:Disp "notwalkonable
:End


something like that would be perfect.

Well running a asm program from basic is very slow, so make it an app? Also I didn't know you made codex! kudos Razz.

Yea... that was always my one complaint with CODEX's spriet routine, using the Asm( command made it sloooowwwwwww.

That's precisely the reason I want to kick it into high gear as well as maintaining a userfriendly atmosphere. It was also slow due to the fact that it required constant input from the basic program, so it was constantly loading and unloading the asm program everytime you displayed each sprite.

The new way, the program would display the entire map in one go, thus saving thousands of cc and displaying the map almost instantaneously.








As for the Matrices thing. I can do it like that, however it will cause the maps to be considerably larger due to the fact that matrices use floating point numbers which if I remember correctly take 9 bytes for each element. It also will make codex bigger as matricies can be difficult to access using assembly when trying to read from a complex variable and displaying the corresponding tile to the screen consecutively.

I like 12 by 12 tilemapping with 2 blank pixels on the top and bottom. I know this is strange and not a nice multiple of 8 but it would be awesome if someone made a tilemapping feature for doing it that way.

Sprites: 8x8, though I haven't found a good looking full body one.

Here's my thought. Have the map tiles at a set standard of 8*8 but have the character sprites be able to be displayed seperately and at a variable size.

So why are you doing this if xLIB is already out there? I'm just curious; go ahead if you think it's a good idea. Since tr1p1ea told me that he does not plan to add a CAT display routine to xLIB, would you be willing to put it in Codex?

I would stay away from matrices if I were you. Not only are they inefficient memory-wise, they are a lot slower to access than pxl-Test(). Most programs that use matrices for storing maps could be improved by using a different method, unless they are on the home screen or need to use the special matrix functions.

It might be nice to be able to set the tile size to accomodate the different tastes shown here: 6x8, 8x8, 12x12.

What if you put 4 blank pixels on the bottom and use it for a stat bar? Try using YUKI's Nine-Dots Minimum Font, or my variation on it:

Why don't you make a new topic so we can try to help. I don't want to get offtopic (like I am right now :blush: ).

I think it is save to asume that this is dead...


can't we put all the dead featured projects in a different section, so new members know which projects are dead and which projects aren't?
