What I didn't mention is that each additional pair would increase the number of tokens in MMBasic by two. I don't think there are any more slots available! I think that a pre-processor, written in MMBasic, would probably work, but it would add steps (save prgram file, load preprocessor, run it pointing at the new program, load the preprocessed program) before running a program. The choices of what to include in the token list necessarily leaves a lot of nice gadgets out. Paul in NY |

Re vegipete's repair of my compressed version of ChemiChaos, Pete didn't mention that the up and down arrows weren't appearing (or at least, they didn't on my CMM2 when I finally got to it). That was fixed by changing the color with which they were drawn from the non-transparent black, RGB(1,1,1) to RGB(gray). mode 7,8:w=rgb(white):bk=rgb(gray):dim cr(5):cr(0)=rgb(green): cr(1)=rgb(red):cr(2)=rgb(cyan):cr(3)=rgb(yellow):cr(4)=rgb(blue) cls w:x=13:y=13:for i=0 to 4:circle x,y,12,,,cr(i),cr(i):y=y+26:next i line 13,134,13,154,2,bk:line 13,134,4,143,,bk:line 14,134,22,142,,bk line 13,160,13,180,2,bk:line 13,180,4,171,,bk:line 14,180,22,170,,bk line 30,2,72,2,2,bk:line 34,4,34,112,2,bk:line 67,4,67,112,2,bk: circle 51,112,17,,,bk:circle 51,112,16,,,bk:box 36,90,31,22,,w,w for i=1 to 9: on error skip: blit close i: next i r=w:x=0:y=0:w=26:For i=1 To 8:Blit read i,x,y,w,w:y=y+w:Next i Blit read 9,w+3,0,45,130: x=37:y=16:for i=1 to 4:blit write i,x,y:y=y+w:next i:v=5:b=4:CLS r: d$="ChemiChaos/5 Vials vegipete/lizby":text 160,0,d$,c,1,,rgb(red),r: d$="1=L,2=R;' '=pick/put,r=reload,x=next":text 160,10,d$,c,1,,rgb(red),r: For j=0 To 4:Blit write 9,j*50,100,0:next j:dim t(5,4):restore g: Do:d$="":For i=0 To 3:read l:h$=Str$(l):d$=d$+h$:if l=0 then:cls r:font 5: s$="S A F E !":text 60,100,s$,,,,rgb(green),r:do:loop:endif:next i: e: k=1:x=10:For i=0 To 3:h$=mid$(d$,i*4+1,4):for j=1 to b: c$=mid$(h$,j,1):l=val(c$):t(k,j)=l:t(5,j)=0:blit write l,i*50+10,82+j*w next j:k=k+1:Next i:blit write 6,9,70:p=1:u=0:do:do:c$=inkey$: loop until c$<>"":if c$="1" then:if x>50 then: blit x,44,x-50,44,26,52: box x,44,26,52,0,r,r:x=x-50:p=p-1:endif:elseif c$="2" then: if x<200 then: blit x,44,x+50,44,26,52:box x,44,26,52,0,r,r:x=x+50:p=p+1:endif elseif c$="r" then:box 0,44,320,52,,r,r:box 210,108,w,w*4,0,r,r:goto e: elseif c$="x" then:box 0,44,320,w*2,0,r,r:box 210,108,w,w*4,0,r,r: exit : elseif c$=" " then:if u then:for i=1 to b:n=t(p,i):if n>0 then:exit for:endif: next i:if n=z or i=5 then:i=i-1: if i>0 then:t(p,i)=z:blit write z,x,82+i*w blit write 8,x,44: blit write 6,x,70:u=0:endif:endif:else:for i=1 to b: z=t(p,i):if z<>0 then:t(p,i)=0:x=(p-1)*50+10:blit write z,x,44: blit write 7,x,70:blit write 8,x,82+i*w:u=1:exit for:endif:next i:endif: endif:loop:loop: g: Data 2321,1412,4412,4333,4232,5235,2443,3554,3124,2121,2444,3331,1224,4232 Data 4311,4133,2141,4333,3242,4121,1314,3424,3231,2142,3233,4141,1241,2243 Data 3324,4421,1123,2431,4552,2444,3255,3332,2422,1434,3313,1241,0 I don't understand why I could see the arrows drawn with rgb(1,1,1), could BLIT READ and then BLIT WRITE them, but after CLS(white), BLIT WRITE didn't show them.

Ah, thanks. I'm a version behind on the manual, and that parameter isn't shown. Updated now. "Default value is 4": &B100 = don't copy transparent pixels So 0 is "do copy transparent pixels". I'm still not sure I fully understand. If I did BLIT WRITE 6,x,y on the screen from which I did the BLIT READ 6, everything looked good even without transparency disabled. But after a CLS RGB(white), BLIT WRITE 6 showed nothing. And I had thought that with RGB(1,1,1) instead of RBG(black) I was avoiding the transparency issue. But RGB(gray) works, and looks to me to be close enough to black (and the color doesn't really matter as long as the arrows appear).

Yes, I often struggle with 'black' too. Black is considered transparent. Trouble is, if we specify RGB(1,1,1), the firmware has to translate that to one of the available colours - and it picks ... BLACK ... as the closest one. I wish we could specify palette number to draw with. Then we could map a particular colour number other than zero to RGB(0,0,0) and then draw with that colour number when we want a solid black, and not with the default one. Adds to the fun! I think in the case of the arrows and test tubes, when you BLIT from the white source, the black pixels allow the white background to show through, resulting in nothing displayed. Test with different RGB(x,x,x) to find the darkest that works. Maybe RGB(20,20,20)? Maybe RGB(10,10,10)? Visit Vegipete's *Mite Library for cool programs. |

vegipete, Is it possible that you could post an uncompressed version of your "In Defense of the Green Hills of Earth" program? I'd like to be able to understand it and perhaps modify it. Bill PS maybe that should have been a stipulation of the contest. Keep safe. Live long and prosper. |

Hi Tom, I did try to re-format the program and ended up with over 200 lines. But failed. It didn't work properly. I would have thought that someone would start out with a readable program and continually whittle it down to something incomprehensible and the original version would still be available. Never mind.

| vegipete Guru Joined: 29/01/2013 Location: CanadaPosts: 1082 |
You are assuming there was an uncompressed version of "In Defense of the Green Hills of Earth".  The first half was written right from the start at 50-75% compressed, to test if it was remotely possible. There was even a major internal re-write, changing the alien formation from 2 arrays of strings to arrays of relative x and y coordinates. (I was quite surprised when the rewrite worked perfectly first time.) The rest of the program was embellishments, added as space allowed. A new routine may have been written mostly expanded, then squashed mercilessly. Sometimes preexisting sections were expanded somewhat to slide in new functionality, or modified. However, I will post a properly formatted version, with comments and all. Might be a day or two... Visit Vegipete's *Mite Library for cool programs. |

Sorry to be late replying. Yes, RGB(NOTBLACK) does work. (I had forgotten about that, but mistakenly thought that RGB(1,1,1) would handle the issue, not thinking through the vagaries of what it might mean in different modes.) Idle musing: what manner of beast is NOTBLACK? It isn't a variable, because you can't set it. It isn't quite a constant because its value depends on the mode. Is it a "variable" constant? Or a pseudo-constant? Similar to but not the same as mm.FontHeight. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

I think RGB(NOTBLACK) is simply wired into MMBasic, same-way as other color constants. And it simply choses for current MODE color with most black but not BLACK and no transparency (for me mostly &hF002000). But Peter can answer it better...

OK here is my entry for the BASIC 10 liners. I simply loved this challenge. And since I use a CMM1 I cannot really compete with the 100x48 challenge on CMM2. A CMM1 basic is simply cannot match up to CMM2 basic. My entry: TLS = Ten Line Sokoban It runs on a CMM1 on MMBasic V4.5c. MMBasic on the CMM1 is much older than the current 5.0x versions running on CMM2 and micromites. And it has some very strange limitations. 1/ Although DO can be anywhere on a multi statement line, LOOP must be at the beginning of a line. 2/ Same for FOR and NEXT 3/ There is no RESTORE nn (restore data read pointer to a certain location) 4/ There is no MIN/MAX 5/ No select/case Originally I wanted to put TETRIS in 10 lines, but that simply would not fit (not with my programming capabilities). Hence Sokoban. Sokoban is a game where a warehouse guy (yellow circle) has to push boxes (green blocks) from their current location to the destination (blue field).Once he completes the task, you get a new level. Pushing the "r" (lower case) will let you redo the game. Here is the Sokoban game in 10 lines s=13:Dim f(s,s),t(s,s):Do:Mode 4:z=9:Read x,y:For i=1To s:Read a$:l=Val("&h"+a$) For j=1To s:w=2^((j-1)*2):m=3*w:f(i,j)=(l And m)/w:If f(i,j)<2Then t(i,j)=f(i,j) Next j,i:Print @(99,10)"TLS":f(x,y)=4:Do:If a$="r"Then:Restore:Exit Do:EndIf:d=1 For i=1To s:For j=1To s:k=f(i,j):If k=1Then:d=0:EndIf:o=120+z*(i-6):p=100+z*(j-6) Line(o,p)-(o+z-2,p+z-2),3And k,BF:If k=4Then Circle(o+z/2-1,p+z/2-1),3,6,,F:EndIf Next j,i:If d=1Then:Exit Do:EndIf:Do:a$=Inkey$:Loop While a$="":n=3And Asc(a$) If n<2Then:b=0:c=n*2-1:Else:b=n*2-5:c=0:EndIf:e=x+b:f=y+c:If f(e,f)=2Then If f(e+b,f+c)=<1Then:f(e,f)=0+t(e,f):f(e+b,f+c)=2:Else:b=0:c=0:EndIf ElseIf f(e,f)=3Then:b=0:c=0:EndIf:f(x,y)=t(x,y):x=x+b:y=y+c:f(x,y)=4 Loop:Loop:Data 2,2,FFFF,D5F3,CBC3,C023,C3CF,EC0F,C0FF,FFFF,0,0,0,0,0 For those who want to understand what the above does, here is some explanation of all these single character variables.

Ten Line Sokoban. Nice. I had to fire up my original Colour Maximite to give it a test. Wow! That's pretty awesome! I wrote a Sokoban clone for the CMM2 a while back and it took me considerably more than 10 lines to do it, so I had to see what cool tricks you used. Your legal move evaluator algorithm is way more elegant than mine. I have discovered thought that I can cheat and stand on the last target instead of pushing the last block in to place.

The only change I had to make to the program to run it on a CMM2 was add OPTION LEGACY ON to the beginning and change variable f to g You can not have a simple variable with the same name as an array.

Good find, I missed that one. I knew about the limitation for CMM2, and thought I fixed them all, but missed the double use of f as variable and as array. Thank you for reviewing. I really appreciate you took the time to play with this baby, since it took quite some time to make. This is a very good reward !! I'll see if I can fix vegipete's cheat within the 10 lines.

Make 2 changes. Line 5 you are missing then ':' after THEN Line 6 remove the first 'DO' so you just have 'EXIT' instead of 'EXIT DO'. In this case, you can get away with it but not something that will always work. (Not sure if it is the same on the CMM1) Jim VK7JH MMedit MMBasic Help |
