Question about predictable random generator about avatars-api-middleware HOT 4 CLOSED

@BaileyMillerSSI you are correct that if the hashing function changes the outcomes will change.

I encourage you to look at the SlotMachine class and its tests, but in essence our hashing works like this: given a collection of outcomes (e.g. avatar images) and a hashing function that returns an integer (e.g. "sum all the character codes in the string"), we get an instance that will return one of the outcomes when passed a string.

I hope that sets you on the right path. If so, please do close this issue.

The code is all right here, so I will again encourage you to browse the codebase if you have more questions. Thanks for your interest!

My friend is looking to do something similar for a school project so I am trying to help with the code. Your @slots variable is an array of images, or in the test case file1, file2, file3, file4, file5. Then you call the pull method with your input string, in the case of the demo website this can the username, or anything really.
Pull returns a variable out of the @slots array of images, in the test case again file1, file2, file3, file4, file5, and what you do is you go var eyes= SlotMachine.pull('inputString'); var nose = SlotMachine.pull('inputString'); where SlotMachine will be a different machine for each category, eyes, face, etc. Then at the end you have some code that creates an image by combining all these variables.

@rylnd Aside from the literal hashing function and the image creation code, did I get that correct?

@BaileyMillerSSI yes, I think you've got it.

The eyes/nose stuff is for the more complicated v2 endpoint with several slotMachine instances for each part of the image, and would be closer to

var eyes = (new SlotMachine(eyesCollection)).pull('inputString');
var nose = (new SlotMachine(noseCollection)).pull('inputString');

The v1 endpoint is the simpler one that I'd suggest you start with; it does the "hash the string and pick an image file" logic, as opposed to building up the image programmatically. The general concept is the same in both cases, though.

Also, @itsthatguy just rewrote the code for es6, so I would suggest looking at the develop branch as opposed to master.
