Number grid map?

| Hi people. A while back, I recall playing an "escape the maze" type game. This was a basic game, nothing really special. But what I found interesting was that the mazes were created using a grid of numbers read from a .txt file, looks like this: 11111111 10100011 10001001 10111101 10120001 11111111 0=Empty space, 1=Wall, and 2=Maze exit. I'm wondering, could you do this with Blitz3d, and if so, how is it done? Thanks! Zaraki |

| To do this you would use the file commands (readfile(), readline(), ) and also the string commands (mid$()). eg Something like this should get you started...
infile=readfile("your text file here")
if infile<>0 then
while(not(eof(infile)))
myline$=readline(infile)
if len(myline)>0 then
y=y+1
for x=1 to len(myline)
cellvalue=mid(myline,x,1)
;then simply store the cellvalue, x and y values in an array
next
endif
wend
closefile infile
else
runtimeerror("file not found")
endif

| Once I created such a testing game, which uses a similar format. http://users.telenet.be/vge/downloads/MazePack.zip Just extract the file somewhere and run the 3 exe's after each other: - MazeGenerator.exe - MazeConverter.exe - Maze3D.exe The first program (MazeGenerator) creates a bitmap for a randomized maze and saves the bitmap as Maze.bmp. The second program (MazeConverter) reads this bitmap, analyses it and creates the file Maze.dat. This is a simply textfile which you can open in Notepad. Every corridor-type has a different code for it. A straight corridor has a different value than a corner. The final program (Maze3D) reads this Maze.dat and creates a 3D version of the maze for you to walk through. It's not optimized or anything, it was only to have some fun walking around a maze instead of solving it on paper. The entire source-code is supplied as well in the subfolders. |
