Need for predictable random generator

Question

I\'m a web-game developer and I got a problem with random numbers. Let\'s say that a player has 20% chance to get a critical hit with his sword. That means, 1 out of 5 hits

Answer 1

City of Heroes actually has a mechanic called the "streakbreaker" that solves exactly this problem. The way it works is that after a string of misses of a length related to the lowest to-hit probability in the string, the next attack is guaranteed to be a hit. For example if you miss an attack with over 90% to hit chance then your next attack will auto hit, but if your hit chance is lower like 60% then you'll need to have several consecutive misses to trigger the "streakbreaker" (I don't know the exact numbers)
