Wavefunction collapse

[chrisws]

The "Wavefunction collapse" algorithm is pretty interesting.

Here's an article that explains how it works.

The example was given in python.  Here's my version in SmallBASIC.

Hi Chris,

Should this Wavefunction collapse.bas code work on SB 12.14 Win64 Mon, 19 Nov 2018 version (Windows 10)?

I am getting error:

Hi Chris,

I am getting error:

Sorry, yes there's a minor bug in 0.12.14 giving this error. Just change the line to

        j = self.wavefunction.get([x, y])
        if len(j) != 1 then

There's also a similar problem in propagate(), change:

        for other_tile in self.wavefunction.get(other_coords)

to:
        j = self.wavefunction.get(other_coords)
        for other_tile in j

To play around, you can also try changing this line

model = Model([15, 20], weights, compatibility_oracle)

and give some other dimensions.

Have fun!

OK that fixed it for me, Thanks!
