Hey, thank you a whole lot for the help.
The graphics are working fine, but I still have a problem with the snake going through stuff. I tried adding a collider to the back of each object, but this tends to happen:
Then I tried putting a collider in front of the balls, but that resulted in some weird behaviour with the controller.
So, I've made a snake controller that mostly works, but the snake is composed of multiple balls, which doesn't exactly look good and is prone to letting stuff through it. I would like to have a mesh and a mesh collider around it, but I have no clue how to do that. I couldn't find a tutorial about it, so if someone could give me advice or forward me to a tutorial, that would be much appreciated.
Here's a picture of the snake.
