[Calc Wars] Help with tilemap?

Copied from my aw_tilem.z80 file.

Code: Select all

``;//Routines for tilemapping, by Patori;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Before doing anything, I think that it'd be best to plan;ahead. hehehe. So anyways, I believe I should discuss the ;program structure, nyo? Ok:;;;   char 'F','L','C','L';   byte width,height;   byte DATA --------------->;   ------------------------->;   ------------------------->;       End, no need for termination bytes, that'd be a waste.;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ///Anyways, the way that the tilemapper would work (or, simply put, it's Algorithm) would be as follows, in poorly written C:;;   Variables:;      width = the map's width;      height = the map's height;      xentry = xposition to draw from;      yentry = yposition to draw from;      bytetostart = pointer to where to start drawing from;      MAR = Random Access Memory (Level data);      tempy = temporary y value;      function drawsprite(x pos, y pos, sprite num) = self explanitory;;   int tileMap(int width, int height,int xentry, int yentry);   {;      //To calculate the max y.... height-4;      int bytetostart;;      if (yentry > (height-4));      {;         tempy = height-4;;      };      else;      {;         tempy = yentry;;      };      if (yentry < 0);      {;         yentry = 0;;      };      if (xentry < 0);      {;         bytetostart = (yentry*width);;      };      if (xentry > (width-4));      {;         bytetostart = (yentry*width) + (width-4);;      };      if ((xentry < (width-4)) && (xentry > 0));      {;         bytetostart = (yentry*width) + width;;      };      //We are pretending that the RAM is a big array called MAR...;      //FIX THIS;      for (int y = 0; y < 4; y++);         for (int x = 0; x < 4; x++);            drawSprite((x*16),(y*16),MAR[bytetostart+(y*height)+x]);;      return 0;;   };;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; In theory, (at least in my theory) this will work. I had to re-re-re-code this like 5 or 6 times. ; Pretty much cuz I was an idiot and didn't think to check X Positions or Y Positions... ^*^. I'll let;Maxcoderz look over it before I convert it into ASM. BTW, units are gonna be loaded in a completely different;way, they start off as arrays of data structures that will be loaded, and checked for relevence with the current;viewpoint that is being displayed.;Well, I'm gonna be really proud if this works :-D;Looking over this code, I realize that it will take forever, and at least 1-2kb to code this in ASM. *gulp*.;I WILL FINISH THIS FOR TICALC.ORG POTY 2005.;;Maxcoderz people (wow! I'm one of these elitists! yay!): I'm sorry that I have not shown any real work as of late,;my home life has went down a toilet. We cannot afford internet, my dad looks for scrap steel for a living, and;I cannot graduate until I can come up with \$1.7k for tuition. (To go to this school, costs \$7k, I have scholarship for \$5k);I've been looking for a job as of late, and even when I get one it will be difficult to save up money for internet ;(I need a phone line turned back on first), and I will likely not have much free time when I work. I'm not asking for pity,; I'm begging for patience and understanding. My life sucks. lol. I'd happy with it though... not really... *goes back to;being a goth at home*;; "It's hard to be a goth when you are an optimist" - A teacher of mine, to me... :-S;; my life may turn around. Mrs. Sinha (Java teacher) spoke of a Database developing job over the summer, and I'm filling out ; tons of apps at various places by my school.``

Do you think this code'll work? Ideas please?

more help

I'd also appreciate help with my load level loop's termination. I'm simply storing the mem addresses in saferam1, saferam1 and saferam1+1 as a pointer to where data was last entered, saferam1+2 data entry point.

Code: Select all

``#define LookSpot saferam3#define LevelList saferam1 ;1 and two for last entry, rest is data            ;In theory, cannot be filled up :) "Luhcky!" - N. Dynamiteaw_load_detect:            ld hl,(ProgPtr)   ld (LookSpot),hl   ld de,saferam1+2   ld (LevelList),deaw_load_detect_loop:   ld hl,(LevelList)   push hl   ld hl,(LookSpot)   ld ix,aw_load_token   call iondetect   pop hl   ;;ex de,hl   ;Erm, rethink, not sure if it will work... hehe. Forum time!, nvm, solved by self.   ld (hl),d   inc hl   ld (hl),e   inc hl   ld (LevelList),hl   ;Will it float?! Will it float?! - Late Show   ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;   ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;   ; Okay, I've determined that there is no real way to check if all of the RAM has ;   ;been scanned with iondetect, at least in the way that I'm using it... So I guess;   ;I'll have to ask those "elitist teenagers" (w00t!) at Maxcoderz for some help,  ;   ;or I can kill myself recoding it... I'll prefer to ask for help at this point...;   ;               -Patori 2/22/05             ;   ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;   ;ld hl,\$0000      ;REALLY NEED TO DOUBLE CHECK... Tired though   ;bcall(_cphlde)   ;jp nc   jp aw_load_detect_loop   ;Infinte for now, until i can Break.aw_load_token:      ;For file detection. Fooly - Coolyin' it up, ^^ Don't wanna be a statistic, "Death by motorbike!" -FLCL   .db "FLCL",0   ;God, if I use obscure Anime references throughout my code, I'll be famous.aw_list_token:   .db "EVAG",0   ;THAT'S RIGHT... Evangelion. "Basically giant robot anime" -FLCL (Go Gainix!);``

Anyways, I need some help with terminating this loop. I believe that there is no safe way of telling whether all RAM has been checked, but I dunno. I may need to re-re-rewrite the code...

height should be width above... oops.

Well, it directly has to do with a project, so... I dunno.

Just figured it'd be more fitting in there since people that can help will probably look in there to help people.

Jeebus, i didnt think you had put this much thought into the game patori! This will be awesome when you complete it .

Above all else, i hope your home situation works out.

Um... I've thought alot about this... I think that that tilemap routine will work....

Currently building a computer outta spare parts from closet... Gonna make a 1337 233mhz, 128mb RAM, 8 GB HDD, 52xCDRom 40x24x40x Burner, floppy drives, and a USB 1.whatever PCI Card... all running windows 98... w00t. Will use specifically for programming on Calc...

Hehehe that sounds fun ... but 233? Anyway, devoting an entire machine to calc coding means comitiment, and i like that! .

Well... playing mp3's too... I need to be able to listen to music at night to get to sleep.... .. I'm having trouble building it though... 233 is the fast processor I could find... the family's fastest comp is a 500 mhz...

If only you lived in my area, I could give you a computer, or at least parts... UMass Amherst is basically giving away 450 mhz PIIs with 256 mb RAm and I think 10 gb HDs... I'm using one as a workstation. 233 mhz, that really bites! My main comp is a 1.7 ghz (but it's an athlon xp, so itsfaster than the clock speed would lead you to believe) with 512 RAm and 120 gb HD.
