Hello all I'm trying to make a feature where a random value gets picked from a list of predetermined values that equal 100 kinda like this Code: item1: chance: 10 item2: chance: 10 item3: chance: 15 item4: chance: 35 item5: chance: 30 I'm currently using just java.util.Random to generate a random number but where I need help is doing a percent chance of getting each entry. EDIT: I have answered my own question I found this post on Stackoverflow and honestly its so simple. I'm embarrassed. https://stackoverflow.com/questions/9330394/how-to-pick-an-item-by-its-probability Code: Item A 25% Item B 15% Item C 35% Item D 5% Item E 20% Lets pretend that all the probabilities are integers, and assign each item a "range" that calculated as follows. Start - Sum of probability of all items before End - Start + own probability The new numbers are as follows Item A 0 to 25 Item B 26 to 40 Item C 41 to 75 Item D 76 to 80 Item E 81 to 100 Now pick a random number from 0 to 100. Lets say that you pick 32. 32 falls in Item B's range. mj
