how do i make a specific randomizer?

[clear flame]

Hello! im trying to make a function where i have 10 parts and after 10 seconds they change colors. BUT out of those 10 parts, i want 1 of them to become red, 2 of them to become green and 7 of them to become gray. How would i be able to do this?

I'm making something @clear flame , once I finish I'll lyk how to make it and send code

[clear flame]

alright

@clear flame Let me ask a few questions, firstly what is your knowledge with Lua and Luau?

[clear flame]

for roblox studio ive been scripting for only 1 year

ive never tried luau for something else than roblox studio

[woeful junco]

well luau is only available for Roblox

[clear flame]

oh then its lua

[woeful junco]

By my understanding you want a randomizer that checks for 10 parts, and wants the parts to be subdivided in "categories" color coded?

[clear flame]

yes

[woeful junco]

It's extremely late rn @clear flame so ima just give u half of what I've done and explain tomorrow

uh

It wont let me send code

Use i,v pairs and math.random

Oh actually

Use for loop to check how many of each colour there are

Example:

if greenCount >= 2 then greenProbability == 0 end
if grayCount >= 7 then grayProbability == 0 end```

Then u use i,v pairs and math.random to randomize the colours based on the sumed probabilities

I suppose u understand the rest if u have 1yr+ lua experience

Yea ur not supposed to spoonfeed

You want certain colours to be more rare, @clear flame?

Or are you just colouring a certain number of parts per random colour?

[clear flame]

Certain colors to be rare

[torn swift]

You're looking for the Weighted Random algorithm

[clear flame]

So what does that mean?

[torn swift]

?

[clear flame]

What is the weighted random algorithm

[torn swift]

Mate. You live in the 21st century. Google it

TL;DR: It's an algorithm that enables you to attach weights (chances) to values so you can directly manipulate the likelihood of getting one of those values

Womp womp I want a challenge
