  6. across the street I came across a discussion about skew, normal and uniform distributions for use in LSL game code as this is a new forum interface and as I have started over again recently then for my first post under my new tag I will repost on here what I posted over there + a 2-die multi-face method that skews from a normal distribution at one end to a uniform distribution at the other end integer twoDx(integer a, integer b, integer m) { integer n = ((integer)llFrand(a) + (integer)llFrand(b)) % m; if (a > b) // skew low return m - 1 - n; return n; } default { state_entry() { list counts; integer i; integer rounds = 500; integer die1 = 5; integer die2 = 6; integer magnitude = 10; for (i = 0; i < magnitude; i++) counts += [0]; for (i = 0; i < rounds; i++) { integer value = twoDx(die1, die2, magnitude); counts = llListReplaceList(counts,[llList2Integer(counts, value) + 1], value, value); } for (i = 0; i < magnitude; i++) llSay(0, (string)i + ": " + llList2String(counts, i)); } } distributions for magnitude = 10 and one die having 5 faces twoDx(5,6,10) :: normal values: 0 1 2 3 4 5 6 7 8 9 counts: 1 2 3 4 5 5 4 3 2 1 twoDx(5,7,10) :: skew hi values: 0 1 2 3 4 5 6 7 8 9 counts: 2 2 3 4 5 5 5 4 3 2 twoDx(8,5,10) :: skew lo values: 0 1 2 3 4 5 6 7 8 9 counts: 3 4 5 5 5 5 4 3 3 3 twoDx(5,9,10) :: skew hi values: 0 1 2 3 4 5 6 7 8 9 counts: 4 4 4 4 5 5 5 5 5 4 twoDx(5,10,10) :: uniform values: 0 1 2 3 4 5 6 7 8 9 counts: 5 5 5 5 5 5 5 5 5 5
