ā N puzzle game Im getting a random color everytime I slide the puzzle
Hey! Im creating a n puzzle game and im almost done however im stuck at something. Everytime I move my blankspace to sort the numbers I get a random color and when I move it again I get a new color which I dont want. I want it to randomize the colors once then it should be the same colors all the time. Here's my code: https://pastebin.com/rdzRtejU

Why are there so many blank lines randomly throughout the code? Near impossible to read it.
new Random().Next(256) please don't do this, especially not multiple times
if you are using a modern .NET version, use Random.Shared.Next(256) instead, and if using an older version, make a single random instance and reuse thatThere reason behind the black lines was to make it more understandable for myself to read the code. Will Random.Shared.Next(256) this one solve my problem ?
Probably not.
@Fayaz Are you doing that number slidy puzzle?
And you are trying to randomize tile colors I suppose?
yes exactly
Ok, there are two very different ways
There's the really easy way of using some associative container and generating a random color at the start, and keeping it around. For example, a
Dictionary<int, Color> or whatever can work fine for that
The other way is a bit more... advanced, but does not require an additional container. You have a list of all the colors, then generate a number m that is a relative prime to colors.Length, and a k offset (names don't matter, it's just textbook convention). Then the tile with the number i on it would get the colors[(m * i + k) % colors.Length] color
The former is what I guess most would do
The latter is just a fun thing if you know hashing šThank you, for the answer. I will try the first solution you provided. If I did not manage to solve it, i'll ask for more help. I have some knowledge about hashing but not in c# only in c. š

Alr, good luck with it!
