How to create rotating wheel object & harmful spikes

Hi, I know how to make solid objects for my Sonic fangame, but here is one that I am trying to make, its a rotating wheel that Sonic spins around on, but I am trying to get it to rotate aka spin 360 degrees, I tried animating it using frames, but when I go to turn it in the editor one certain way it looks as if a tiny section is cut off., I also know how to make spike objects, and use the qualifiers 0 and 2 for them, but one problem is on the right side Sonic gets stuck and I have to struggle to get him lose, the top part of the spike is what I am trying to make dangerous. here are the images.Attachment 21859Attachment 21860

I cant help with the circle.

The spikes:
You're going have to make fusion check for your player going downwards. What platform movement is you using? If it's the platform movement object you can check for something like "player is falling" combined with "Player collision with spike object".

If you dont have PMO You can also try "Player direction is DOWN"+ Collision with spike object. Unsure how that will work though.

If I understand the question about the wheel correctly you could try

Every X seconds
Set angle of "wheel" to "angle of wheel" -1 (for clockwise movement)
Set angle of "wheel" to "angle of wheel" +1 (for anti-clockwise movement)

Change the value to higher than 1 in both examples to speed up the wheel

I tried to learn from an example I downloaded yesterday, it was a wheel that was multicolored, spinning wheel example is the name if I recall correctly, it had the alterable values, but were named velocity and angular, I tried using those codes for the wheel that I am making, but still no success.

This is the code that I am using for the spinning wheels in my game, I am using an example that I downloaded the other day.Attachment 21883
