How to use percentage, im kinda confused?
I made something like percentage for dropping fishes. For example, Fish 1 has 30 % to be dropped but Fish 2 has 70%. I was trying to use math.random but it didn't work. Any suggestions on how to do it( with explanation and modifying percentage). // Edit, another problem
01 | local rod = script.Parent |
02 | local pomost = game.Workspace.PomostLvl1 |
03 | local FishOdds = math.random(1,100) |
04 | local Fish1Odds = 1,30 |
05 | local Fish2Odds = 31,100 |
06 | db = false |
07 |
08 | pomost.Touched:Connect(function() |
09 | rod.Activated:Connect(function() |
10 | db = true |
11 | if FishOdds == Fish1Odds then |
12 | wait(1) |
13 | print("Catched fish number 1!") |
14 | db = false |
15 | end |

Try doing math.random(1,100) and then get percentage of it, e.g.
01 | --Make a random value between 1 and 100 |
02 | local percentage = math.random(1,100) |
03 |
04 | if percentage <= 30 then |
05 | --If percentage is lower than 30, <= 30 |
06 | print("<30") |
07 | else |
08 | --If percentage is higher than 30, => 30 |
09 | print(">30") |
10 | end |
There are a couple issues here..
You are attempting to assign 1 variable to 2 values. You should be using a table.
FishOddshas been defined outside of the event; therefore, shall only ever return the same thing. Define inside theActivatedevent to get different results every time it fires.You are comparing the FishOdds result incorrectly. You have used the
==equivalency comparative operator when you should have used>=and<=to specify a spectrum.Your debounce has no condition, you are just toggling a bool which is doing nothing.
01 | local rod = script.Parent |
02 | local pomost = workspace:WaitForChild("PomostLvl1") |
03 | local Fish1Odds = {1,30} --Use tables |
04 | local Fish2Odds = {31,100} |
05 | db = false |
06 |
07 | rod.Activated:Connect(function() |
08 | if db then return end --Debounce condition |
09 | db = true |
10 | local FishOdds = math.random(1,100) --Define inside the event |
11 | local note = " " -- <= and >= for spectrum |
12 | if FishOdds >= Fish1Odds[1] and FishOdds <= Fish1Odds[2] then |
13 | note = "Caught fish number 1" |
14 | elseif FishOdds >= Fish2Odds[1] and FishOdds <= Fish2Odds[2] then |
15 | note = "Caught fish number 2" |
16 | end |
17 | wait(1) |
18 | print(note) |
19 | db = false |
20 | end) |
Note: Not sure what you were trying to do with the Touched event..

If we wanted to calculate the probability of landing heads when flipping a coin once, we'd take the number of values that'd meet how condition (landing heads), which in this case is one, and divide it by the number of all possible outcomes, 2; so, we'd represent it as 1/2, 50%.
We want to do the same thing here, so first we'll establish the number of outcomes that'd fufill our condition. In your case, 0-30 for fish1, so 0 <= n <= 30. Next, we need to get a randomly generated number from our range, which in your case is 100, which we can do using math.random(0,100), giving us 100 possible outcomes. So, 1/30 or 30%.
1 | if math.random(0, 100) <= 30 then |
2 | -- spawn fish1 |
3 | end |
And, since Fish2's spawn rate happens to also be 70%, the probability of Fish1 NOT spawning, we can express both as
1 | if math.random(0, 100) <= 30 then |
2 | -- spawn fish1 |
3 | else |
4 | -- spawn fish2 |
5 | end |
