please tell me how to generate 5 different non repeatable random number between 1,20 in javascript for unity3d
this the code i have written.. this works 1st 3 times but crashes the last time. please tell me how i can improvise this i have taken numbers in an array to print them on screen n n checked for their repeatability. this works ly 3 times.. for 4th time unity crashes. i know the reason dunno how solve it.. i think it is because it is not able to detect the remaining numbers of the array. Please tell me where i have gone wrong.. i’m new to unity.

One way to go about this would be to create the array of possible values, shuffle it, and look at the first five elements:
