I got an email asking me if I can share how I build a spin wheel in Challenge#188. So I wrote this post to explain how I did it. You may like to see the demo first. Ok, here is how I built it. Create a spinnable wheel First of all, I need a wheel so I inserted one from the content library. And to make it able to spin I duplicate and crop it to the spin area and then covert it to dial. To make it spin smoothly and have multiple circles, I set the rotation equal to 3600 and the value from 0 to 9999. Make it spins for a period of time after hitting a button I like the wheel randomly spinning while a sound effect is playing after hitting a button. To control the wheel spinning or not spinning, I added one T/F variable (I call it “STOP”) to do the magic, the wheel will only spin when variable STOP is equal to False. To make the wheel spinning for a period of time is to keep changing the value of dial in the period I want. So I created a little rectangle and make it able to quickly move up and down in loop during the period (Sound Effect playing). Create a loop: Move the rectangle up when motion down completes, move the rectangle down when the motion up completes on condition of variable STOP=False. Here, the loop will be ended when a trigger changes the variable STOP. Changing the dial value: add a random number to variable Dial when the animation completes up or down. So the dial value will keep changing while the looping exist. 2. Trigger a start and play a sound effect, there are four triggers to do so. Set variable STOP=False when clicking the BTN: this allows the wheel to spin because the object only moves on condition of variable STOP=False. Move the rectangle when clicking the BTN on condition of variable STOP=False. Set variable Dial=0 when clicking BTN to make sure it will turn when hit the BTN. Trigger the sound effect when variable Dial changes. 3. Stop spinning when media completes Set default variable STOP = false, and then set a trigger to adjust variable STOP equal to True when media completes. So the wheel spins and a sound effect plays when clicking the BTN by STEP 2, keep spinning while the sound effect playing by STEP 1 and stop spinning once the sound effect ends by STEP 3.

Love it. I knew increasing the number of dial stops would increase the smoothness of the rotation but worried that it might also slow down the rotation too much. Clearly, this is not the case and my concerns are gone! I'm going to have to go back and add some stops to my spinner.

This is best spinning wheel example I have seen so far. Thanks for sharing.

How do you handle the prize selection with so many variables. It spins but I cant tell you what happens when you land on area 1 vs area 2

I am very new to storyline, and im really struggling to get this to work. Anyone able to offer any advice so that I can have 8 segments, landing on a different one each spin, and revealing the content that it lands on. I also cant seem to get my circle to stay neat in the middle it spins all over the page! Sorry, complete newbie. Thanks,

Hi Rachel! Welcome to the E-Learning Heroes Community! I reached out to my team and Trina found this quick solution to centering the spinning wheel. It’s landing on a different part each time, so the random variable Joanne used, seems to be working great in your file too. I’m curious to see if any other community members have done anything similar to add custom content depending on each spin.

How to make a spinning wheel in SL (no JS need)

I got an email asking me if I can share how I build a spin wheel in Challenge#188. So I wrote this post to explain how I did it. You may like to see the demo first.

Ok, here is how I built it.

Create a spinnable wheel

First of all, I need a wheel so I inserted one from the content library. And to make it able to spin I duplicate and crop it to the spin area and then covert it to dial.

To make it spin smoothly and have multiple circles, I set the rotation equal to 3600 and the value from 0 to 9999.

Make it spins for a period of time after hitting a button

I like the wheel randomly spinning while a sound effect is playing after hitting a button. To control the wheel spinning or not spinning, I added one T/F variable (I call it “STOP”) to do the magic, the wheel will only spin when variable STOP is equal to False.

To make the wheel spinning for a period of time is to keep changing the value of dial in the period I want. So I created a little rectangle and make it able to quickly move up and down in loop during the period (Sound Effect playing).

Create a loop: Move the rectangle up when motion down completes, move the rectangle down when the motion up completes on condition of variable STOP=False. Here, the loop will be ended when a trigger changes the variable STOP.
Changing the dial value: add a random number to variable Dial when the animation completes up or down. So the dial value will keep changing while the looping exist.

2. Trigger a start and play a sound effect, there are four triggers to do so.

Set variable STOP=False when clicking the BTN: this allows the wheel to spin because the object only moves on condition of variable STOP=False.
Move the rectangle when clicking the BTN on condition of variable STOP=False.
Set variable Dial=0 when clicking BTN to make sure it will turn when hit the BTN.

Trigger the sound effect when variable Dial changes.

3. Stop spinning when media completes

Set default variable STOP = false, and then set a trigger to adjust variable STOP equal to True when media completes.

So the wheel spins and a sound effect plays when clicking the BTN by STEP 2, keep spinning while the sound effect playing by STEP 1 and stop spinning once the sound effect ends by STEP 3.
