Wave Function Collapse - aadityap0901 - 07-06-2024
Hello, this is my first post.
I don't know where to post this, this place looked likely.
I learnt WFC yesterday, and it seemed easy, so I thought I would code and share it as my first program on this new forum:
If anyone wants to change images, you can change it in LoadImage function.
I wanna see how people use this idea, please share your creative designs (if possible)
.Code: (Select All)

Welcome again @aadityap0901
a little introduction:
I think Aaditya is rising star like Ashish, only 18 years old from India. I had to invite here because of the work I've seen at the other forum and just about to start college.
I haven't tried the code yet but am sure it will be interesting
RE: Wave Function Collapse - bplus - 07-06-2024
Ah cool, luv it!
Nice graphic, now to study it to see what makes it tick
This is way different than other bit of code I'd seen under Wave Collapse Function title.
RE: Wave Function Collapse - a740g - 07-06-2024
Welcome to the QB64-PE forum Aaditya.
RE: Wave Function Collapse - bplus - 07-06-2024
Ah there's a guy whose brain you might wanna pick!
RE: Wave Function Collapse - aadityap0901 - 07-06-2024
Added a new tile and increased the size of the grid

RE: Wave Function Collapse - bplus - 07-06-2024
Nice you cut the LOC by half by replacing DATA with images looks like it tiles in trapazoid screen fills now also.

WFC based Sudoku Solver, cannot solve hard sudokus unfortunately
An example sudoku is loaded, but you can use arrow keys and numbers from 0 to 9 (0 to clear) to input in grid...
Hit enter and see the magic
Code: (Select All)
Screen _NewImage(18, 11, 0)
DefLng A-Z
Dim Grid(1 To 9, 1 To 9) As _Unsigned _Byte

What is encouraging is that the numbers it did fill in were correct.
