My spin wheel wont land on the prize that was chosen

[ituzis]

1. What do you want to achieve? Keep it simple and clear!

2. when i spin the wheel, it should stop on the chosen reward.

3. What is the issue? Include screenshots / videos if possible!
   it does not stop on the chosen reward, instead it lands on something totally different.

local plr = game:GetService("Players").LocalPlayer
local TweenService = game:GetService("TweenService")

script.Parent.Frame.Wheel.SpinButton.Frame.TextLabel.Text = "Spin! (" .. plr.SpinsData.Spins.Value.. ")"

local rewardsTable = {
	[1] = {script.Parent.Frame.Wheel.innerpart:FindFirstChild("1"), rarity = 15},
	[2] = {script.Parent.Frame.Wheel.innerpart:FindFirstChild("2"), rarity = 5},
	[3] = {script.Parent.Frame.Wheel.innerpart:FindFirstChild("3"), rarity = 10},
	[4] = {script.Parent.Frame.Wheel.innerpart:FindFirstChild("4"), rarity = 15},
	[5] = {script.Parent.Frame.Wheel.innerpart:FindFirstChild("5"), rarity = 10},
	[6] = {script.Parent.Frame.Wheel.innerpart:FindFirstChild("6"), rarity = 20},
	[7] = {script.Parent.Frame.Wheel.innerpart:FindFirstChild("7"), rarity = 20},

end)

Make it so you have 100% of chance to get a prize and test it 2 times to see if you always land on the same thing. If you do, then adjust it. After make it random again and test if it works.

What will that exactly solve? Ive tried this.

[mmii665 (Mmii)]

I thought maybe there were extra degrees.

There’s 110 percent fully… meaning all the items % sums to 110… I think.

I tried your script and it works really well. When I force it to land on the third index, it always gives me 4:

The first print is the index and the second one is the rotation:

Example: If the index is 3 , then give the player 4 coins, if index is 4 then 5 coins etc.

Alright, well I solved it anyway. thanks for the help though.

Btw I wouldn’t use FindFirstChid() for anything that’s not being checked if it exists. I’d use WaitForChild() since you’re storing the item and it may mess up your script if the game loads slowly.
