[Mod] Random API

[TheFanne]

A simple, easy-to-use API for choosing random objects from a list with probabilities.

How to use
First, create a Random object using Random:new(), then add all your items using Random:add_choice(choice, probability), and finally, call Random:calc_csum().

When you want to get an item from the list, simply call Random:choose().

Use examples
It is used in my game called Raining Nodes (https://content.minetest.net/packages/T ... ing_nodes/)

Why not simply local myrandomvalue = mytable[math.random(#mytable)]?

Why not simply local myrandomvalue = mytable[math.random(#mytable)]?

That doesn't support propabilities unless you put entries with higher propablility into the table multiple times.

Well, yes, that's the only downside. But in return the random selection is reduced to one single statement. So if you don't care about probabilities you're good to go.
