Simple Maze Designer
« on: June 26, 2019, 06:18:34 pm »
I just thought I would toss this little program I made this afternoon into the mix. It's a simple plotting/drawing program to mostly use with other games or programs we make in the future. There's no color changes, just white lines. I'm not very good at making a color picker and just using numbers would be pretty random for me so I just stuck with white. Of course you can add color or anything you wish to this if you want. It uses a 640 x 480 screen with 10 x 10 plots. There is a limit of 10,000 plots but that would fill up the whole screen and more and the size of the file that would save as would be around 100 KB. The saved files have an .aze ending (maze without the m). I couldn't find a file ending on Google that has that ending so I stuck with it. The file it makes doesn't have a color number on it so when you load it with your own programs, you will need to add that. You use the arrow keys and space bar to change from pen up to pen down and vice-versa, S to save, L to load. There is no printer support with this one because of the 10 x 10 pixels would be heavy on the ink. This is just something I tossed together within about 3 hours. :) Enjoy.

- Code deleted because of a much better update I made below on my post.

Hi Ken,

Reminds me of Etch-A-Sketch. Have you thought about an eraser? change a cell back to black.

Oh, how can you compare Picaso with an "Etch-a-Sketch"?

But you could be right about an eraser. If so, would it not be better to have the 'cursor' as a empty box, just so you can tell where it is? Just a thought.

I thought about an eraser but since I use t=t+1 x(t) y(t) and just create the picture file with those coords, it would be too hard to try and go back and erase it since I don't use colors. But I'm glad you guys like it. :) I also thought about a cursor, but that is a bit beyond me as well. I used to know more about such a thing but am not completely back to how I was in the 90's. I remember a command named XOR where you can put graphics over graphics. Someday I may look into it again, but I'm just going to keep this program the way it is. :)

In a nutshell you can draw a square (or whatever shape you choose) for a cursor, use _hidemouse(), then display the shape at mouseX and mouseY. Well, that's what I think could work... you may have to check with the others...

Hi. And what to do a little differently. Left-click to paint the block, right-click to delete it. Save it by pressing S. Load map by pressing L. And moreover ... the map is not limited to one displayed field, so press the up, down, left and right keys to move around the map. It's just a quick sketch. Basically the basis in which I make a maze editor.

Code: QB64: [Select]
  1. 'maze edit fast
  2. SCREEN _NEWIMAGE(640, 480, 256)
  3. REDIM maze(100, 100) AS _BYTE 'total map contains 10.000 cells
  4. CONST map$ = "Mazemap_textfile.txt"
  5. 'create cells 20 x 20
  6. FOR y = 0 TO 460 STEP 20 '23 steps
  7.     FOR x = 0 TO 620 STEP 20 '31 steps
  8.         LINE (x, y)-(x + 19, y + 19), , B
  9. NEXT x, y
  10.  
  11. 'activate mouse for inserting / deleting cell:
  14.     PositionX = Sx + _CEIL(_MOUSEX / 20)
  15.     PositionY = Sy + _CEIL(_MOUSEY / 20)
  16.  
  17.     IF PositionX > UBOUND(maze, 1) THEN PositionX = UBOUND(maze, 1)
  18.     IF PositionY > UBOUND(maze, 2) THEN PositionY = UBOUND(maze, 2)
  19.  
  20.     IF _MOUSEBUTTON(1) THEN maze(PositionX, PositionY) = 1
  21.     IF _MOUSEBUTTON(2) THEN maze(PositionX, PositionY) = 0
  22.  
  23.     'add keyboard support for map edit move up, down, left and right
  24.  
  25.     i$ = INKEY$
  26.     SELECT CASE i$
  27.         CASE CHR$(0) + CHR$(72): Sy = Sy - 1 'up
  28.         CASE CHR$(0) + CHR$(80): Sy = Sy + 1 'dn
  29.         CASE CHR$(0) + CHR$(75): Sx = Sx - 1 'up
  30.         CASE CHR$(0) + CHR$(77): Sx = Sx + 1 'dn
  31.  
  32.             'and after "S" pressing it save this map to file:
  33.         CASE "S", "s": GOSUB SaveIt
  34.  
  35.             'and after "L" pressing, load it from file mazemap_textfile (if is previously saved)
  36.         CASE "L", "l": GOSUB LoadIt
  37.     END SELECT
  38.  
  39.     IF Sx > UBOUND(maze, 1) - 32 THEN Sx = UBOUND(maze, 1) - 32
  40.     IF Sx < LBOUND(maze, 1) THEN Sx = LBOUND(maze, 1)
  41.     IF Sy > UBOUND(maze, 2) - 24 THEN Sy = UBOUND(maze, 2) - 24
  42.     IF Sy < LBOUND(maze, 2) THEN Sy = LBOUND(maze, 2)
  43.  
  44.     Ex = Sx + 32
  45.     Ey = Sy + 24
  46.  
  47.     IF Ex > UBOUND(maze, 1) THEN Ex = UBOUND(maze, 1)
  48.     IF Ex < LBOUND(maze, 1) THEN Ex = LBOUND(maze, 1)

  57.             SDy = 20 * (dy - Sy - 1) 'SDY = start draw Y
  58.             IF maze(dx, dy) THEN
  59.                 LINE (SDx, SDy)-(SDx + 18, SDy + 18), , BF
  60.             ELSE

  62.             END IF

  65.  
  66. SaveIt:
  67. IF _FILEEXISTS(map$) THEN KILL map$
  69. OPEN map$ FOR OUTPUT AS #f
  70. FOR recX = LBOUND(maze, 1) TO UBOUND(maze, 1)
  71.     FOR recY = LBOUND(maze, 2) TO UBOUND(maze, 2)
  72.         IF maze(recX, recY) THEN
  73.             PRINT #f, STR$(recX); ","; STR$(recY); ","; STR$(maze(recX, recY))
  74.         END IF
  75. NEXT recY, recX

  78. SOUND 150, .3
  80.  
  81. LoadIt:
  83.     REDIM maze(UBOUND(maze, 1), UBOUND(maze, 2)) AS _BYTE
  84.     f = FREEFILE
  85.     OPEN map$ FOR INPUT AS #f
  86.     DO WHILE NOT EOF(f)
  87.         INPUT #f, x, y, value
  88.         maze(x, y) = value
  89.     LOOP
  90.     CLOSE #f
  91.     SOUND 150, .3
  92. ELSE BEEP 'file not exists
  95.  
  96.  


As you can see, the value "1" is written for the filled cell in field. So here's a lot of options: Suppose 1 will be an ordinary wall. 2 will swamp, 3 need sand .... and everything will have different characteristics. Or with a small adjustment you can create a platform game. Anything. Of course, you can write more map layers to the same place (by adding more fields or just variables to the fields), for example, to run some timed activity, or for sound.

That's really cool Petr! I liked the grid a lot so I put it into my program. I also figured out how to make a red box so you know where your plot is going to be before you make it. I'm still using the arrow keys because personally I think it's easier than choosing 1 square at a time with a mouse. I also renamed it and added an eraser. So here it is: :) 

Edit: Code deleted again because I keep adding more things. :)

Sorry for always updating and posting, will try to test programs out more from now on before I post on here.
I made it so you don't see Eraser On when your Pen is Up since you can't erase when your pen is up anyway. Am still working on it and testing it.

I just made something I've wanted to make since the 80's! I used the above program to make a bunch of hallways on 1 picture. Then I made this program below as an example to everyone on how to detect every single wall from the picture. You move the little red dot around with your arrow keys and it stops if you hit a wall. :)))) Imagine the possibilities of games people can make with this! This probably sounds funny to most of you since you all are much higher up in skill than I am, but I am really excited. :) Here is:

Code: QB64: [Select]
  1. 'This is an example on how to detect walls from using a picture made by using Ken's Plotter.
  2. 'First make a picture with Ken's Plotter program and then type in the name of it in this program.
  3. 'This example starts you out in the direct center of the screen.
  4. _TITLE "Maze Loader and Wall Detector Example"
  5. start:
  6. 'You will need to DIM these strings and variables first to make memory.
  7. DIM x$(10000), y$(10000), x(10000), y(10000)
  8.  
  9. 'xx and yy are the coordinates to your red square.
  10. xx = 320: yy = 240
  11. SCREEN _NEWIMAGE(640, 480, 32)
  13. PRINT "Maze Loader and Wall Detector Example"
  15. PRINT "By Ken G."
  17. PRINT "This is an example on how to detect walls."
  18. PRINT "First you need to create a picture or maze using 'Ken's Plotter'."
  20. PRINT "Use your arrow keys to move the little red square around and it will"
  21. PRINT "stop at every wall. In this example, you start out in the very center"
  22. PRINT "of the window."
  24. again:
  25. INPUT "Type file name of picture to load (without the .txt ending):", nm$
  26. IF nm$ = "" THEN GOTO again:
  27. nm$ = nm$ + ".txt"
  28. theFileExists = _FILEEXISTS(nm$)
  29. IF theFileExists = 0 THEN
  30.     PRINT "File does not exist, try again."
  31.     GOTO again:
  34. 'First you load the picture and put every coordinate into memory.
  35. OPEN nm$ FOR INPUT AS #1

I added a couple more lines of code to stop the red square in the Maze Loader and Wall Detector Example, to stop your guy from going outside of the screen. I also decrease 5 numbers from one of the X detection numbers so it goes closer to the wall. 
Here is the newer update:

Code: QB64: [Select]
  1. 'This is an example on how to detect walls from using a picture made by using Ken's Plotter.
  2. 'First make a picture with Ken's Plotter program and then type in the name of it in this program.
  3. 'This example starts you out in the direct center of the screen.
  4. _TITLE "Maze Loader and Wall Detector Example"
  5. start:
  6. 'You will need to DIM these strings and variables first to make memory.
  7. DIM x$(10000), y$(10000), x(10000), y(10000)
  8.  
  9. 'xx and yy are the coordinates to your red square.
  10. xx = 320: yy = 240
  11. SCREEN _NEWIMAGE(640, 480, 32)
  13. PRINT "Maze Loader and Wall Detector Example"
  15. PRINT "By Ken G."
  17. PRINT "This is an example on how to detect walls."
  18. PRINT "First you need to create a picture or maze using 'Ken's Plotter'."
  20. PRINT "Use your arrow keys to move the little red square around and it will"
  21. PRINT "stop at every wall. In this example, you start out in the very center"
  22. PRINT "of the window."
  24. again:

  26. IF nm$ = "" THEN GOTO again:

  29. IF theFileExists = 0 THEN
  30.     PRINT "File does not exist, try again."
