MazeConnect v1.4 - puzzle prototype (iPad only)

[Dav]

This is a prototype of a maze puzzle game. Don't know how to describe it well. What you try to do is rotate the pieces by touching them, trying to make a maze all connect. THe top left maze piece will always be colored. When the other pieces connect to that one, then they will become colored too. When you make the whole maze connect and become colorized you win.

There are two programs posted here. 'MazeConnect.txt' is the game. 'MazeDesign.txt' is the maze designer you can use if you want to make your own mazes for the game.

MazeConnect.txt v1.4 is below... (The game)
New for v1.4: Game board now only updates buttons that have been changed, greatly increasing screen updates on large grids and slower devices.

'MazeConnect.txt v1.4 (ipad only)
'A Maze puzzle game prototype.
'Coded by Dav, OCT/2017

'You touch pieces to rotate them and connect them.
'Object is to make maze all connected and colorized.
'Top left is the first color one. Build from there.

'New for v1.4: New method of updating board pieces.
'              Only redraws buttons that have been
'              changed, not the whole board. This
'              makes gmae play MUCH faster on large
'              grids and on older devices.

Had a typo, fixed it. Maze now works. Reload it if you got it earlier and it didn't work.

[Dutchman]

Great creative idea to use these characters for that. You are the games master

[Mr. Kibernetik]

I agree, Dav is a games master!

[Henko]

Yes, he is.
Dav, here's a brute force piece of code to generate a random path in a n x m grid. From it, you can deduct wich of the two tiles must be placed on each grid point. And don't forget to shuffle the rorational position of each tile.
The needed time is strongly exponential with size. 6x6 is moderate, lower is immediate, 7x7 can be 1 second, but also 20 seconds. It's a brute force method, as i said. After finding a path wich visits all points only once, it is drawn in this test program.

Code: Select all

input "number of columns ? ":ncol
input "number of rows ? ":nrow
graphics ! graphics clear ! draw color 0,0,0 ! draw size 3
option base 1 ! randomize
nturt=nrow*ncol
do
  dim p(nrow,ncol),turtle(nturt)
  curi=1 ! curj=1 ! turt=0 ! p(1,1)=1
  fail=0
  do dim fre(4)
    fail=inspect(curi,curj) ! if fail then break
    do ! td=1+rnd(4) ! until fre(td)=1
    turt+=1 ! turtle(turt)=td
    if td=1 then curj+=1 ! if td=2 then curi-=1
    if td=3 then curj-=1 ! if td=4 then curi+=1
    p(curi,curj)=1
    until fail
  until turt=nturt-1
draw_path()
end

def inspect(i,j)
  fail=1
  if j<.ncol and .p(i,j+1)=0 then ! .fre(1)=1 ! fail=0 ! end if
  if i>1 and .p(i-1,j)=0 then ! .fre(2)=1 ! fail=0 ! end if
  if j>1 and .p(i,j-1)=0 then ! .fre(3)=1 ! fail=0 ! end if
  if i<.nrow and .p(i+1,j)=0 then ! .fre(4)=1 ! fail=0 ! end if
  return fail
end def

def draw_path()
x=100 ! y=100 ! xto=x ! yto=y ! ds=floor(500/max(.nrow,.ncol))
for i=1 to .nturt-1
  td=.turtle(i)
  if td=1 then xto=x+ds ! if td=2 then yto=y-ds
  if td=3 then xto=x-ds ! if td=4 then yto=y+ds
  if i=1 then draw line x,y to xto,yto else draw line to xto,yto
  x=xto ! y=yto
  next i
end def

I have been experimenting a bit with your program, Henk. As you say, it is very fast on smaller mazes, but once they get beyond 10 x 10 in size it can take many minutes for the calculations. Is it possible you could build a series of smaller maze blocks and connect them together? You would have to allow choice of the entry point location for each block so that it could start where the last block ended.

I notice that some mazes finish dead-ended (ie. the finish point is not on the edge) Those would have to be rejected as building blocks, as there would be no way to join them to another block. That would also be true of mazes where the start and finish points are on the same edge.

Perhaps there is no speed advantage, but I thought it was worth mentioning.

A progress bar of some kind would help to reassure that the program had not frozen.

[rbytes]

Great game, Dav. Are there any guidelines on how to solve, rather than trial and error? I ask this because my trials are usually errors.

[Henko]

Good thinking Richard. If it is indeed possible to break down this process in a number of likewise 'linkable' subprocesses, it would certainly dramatically shorten the needed calculation time. But there are other, more intelligent algorithms to connect the points in a grid by visiting the points only once. It is a well known 'salesman problem' in the field of operational research. I guess they can be found on internet. I just have other priorities at the moment to dig further in it.
The calculation time needed by the brute force method that i used is so agressively growing beyond 50 gridpoints, that it is not usable as an "in-line" tool in the game. It could however be used "off-line" to generate large grids for the puzzle, and convert them (with additional coding) into suitable read/data stuff to be added to the game.

[Dav]

Thanks everyone! On my older iPad this game is way too slow to play. I thought of another way to scan the maze, Since each piece has one way in/out when connected, im going to keep track of the direction, and just 'go with the flow' starting with the top left piece. This way I will only have to upend the board pieces that connect, and not the the entire board many times after each turn.

Henko: thanks very much for your code. I can use it to generate mazes!

Rbytes: I don't of any real strategy to solve, maybe look for the long line pipes and see what needs to connect to those?

I'm working on a new version. Hoping to have levels, maybe some blocks, others pieces like a + one that connects any direction.

-Dav

[Dav]

I have re-written the board scanning/colorizing method to a directional one, that goes with the flow so to speak. The result is that board update is now MUCH faster, making it very playable even on my older devices. Now that this hurdle is jumped I can go further with game development (levels,etc).

Code is updated. Try it out of you'd like.
