Tested it in the racetrack scene it gets a list of all the objects at runtime so when the functions are called will trigger them one at a time.
Also got the characters moving correctly with the conveyor belts and the shooting cannon.
Modified the pit prefab (sorry Claire), the surrounding blocks clashed with neighbouring pits/walls/water/etc.
Starting the game will now take you to the 4-player alpha racetrack rather than Colour Collide.
Camera now scrolls along the racetrack level at a rate of 1 block per turn. Currently nothing happens to people who fall behind it, except that you can't see them.
Pets will no longer paint blocks in their colour. (I had to modify the ColorCollide.cs script for this, as I could not figure out how to turn a script into a .asset object as was done for ColorCollide.asset.)
