Efficient way of distributing items

[pgimeno]

It's actually the OP who posted an example that used accumulated weights. I think milon just translated that code so that the same weights came from a table instead of a chain of if's. From that point of view, the choice of wording, "rarity", wasn't too good.

. That's the general idea behind weighted randoms. Does that help clarify?

Yeah, that makes it clearer.
