Random System

[mystic moth]

I'm tryna make a type of Murder Mystery Game And I know how to make a random pleyer select and everything but the only problem I'm having is I want it so something happens when the Detective interigates, and I want it to be a 0.05 or 1/20 Chance To Happen. How would I go about doing this?

(No I'm not taking the suggestion "UsE a RaNdOm InT oR fLoAt" because that's not an actual rarity. While yes that's kinda what a ririty system is doing that's less spot on.)

Why won’t you use a int/float?

is there a reason?

rarity’s are based of numbers…

With what your asking int/float randomizer is perfect for this

You use Random Float

Pick a random number between 0 and 1 (or if you wanted, 0 and 100)
Want a 20% chance? check if the number is less than 0.2, (or if [0,100], use 20)

hell you could do it with Random Int too if you wanted

Pick a number between 0 and 100000, for 20% chance, check if its lower than 20000

I feel like the Random Int Or Random Floats have just about the same chance to get on any number though, like 1 - 10. They all have the same chance to land on any number doesn't it?

I mean, yeah, but what are you asking for?

Do you want to execute the Random Float and have a 1/20 chance of succeeding, 19/20 chance of failing?

This does work, yes but I feel like its not an actual rarity.

Kinda yes. But if this works the same way I'm willing to give it am attempt.

mate thats LITERALLY how you make a random chance system

Pick a random number between 0 and 1, check if the number is less than 0.05 (5% chance)
If True, you succeeded, this will only happen 5% of the time
If False, you failed, this will happen 95% of the time

If you want to work in fractions instead of percentages (eg. 1/20 instead of 5%), pick a random int between 1 and 20 and check if it equals 1
