WARNING: DO NOT OVERHEAT YOUR CPU, THIS PRIME NUMBER GENERATOR CAN USE FULL CPU AND IT MAY CAUSE CRASHING ON OLDER COMPUTERS. I just finished this and didnt make a ui yet, so here are the instructions: download the project, or use the online editor, and first press the spacebar once, then get the script in the top right, the one using the "tests" variable and adding numbers to the list "prime" run that for a while and when you have enough numbers you want to test for primes, then click the "when i receive (blank) broadcast startnotprimecount" script, that will work through all the multiples needed to find prime numbers, there will be an indicator of the progress on the screen named NPrimeGen, when it gets to 100% use the script at the very bottom with all the "if notprime contains item, delete" the percentage progress of this will be on NPrimeRmv, after it is done you will have a list of mostly primes, this isnt 100% accurate as it leaves out lots of multiples it needs, I believe everything before 1680 is reliable though, the first non prime that shows up is 1681 NOTES: The higher you go the less accurate this is, so for ranges above 10m you are unlikely to find an actual prime, i did a test at 50m with 50000 and it turned out with around 35000 viruses detected and out of ~50 primes i checked i only got 3 of them true primes. Viruses Detected is the number of non primes removed from the list. if you want to sample a different range of numbers, you can set the "tests" variable to a higher number, but if you do this you also have to set all the scripts started when the broadcast "startnotprimecount" to that number, for example if you make the variable "test" 50,000 you need to make the variables "3" "2" "5" "7" "11" "13" all 50,000 too.
