For help!
The original case is based on Unity4, what I use is Unity5
Line # 70 and # 89 error, the reason is jumpMaterial is not defined, to be honest I don't understand why this code to this design, ask tall person to give directions

Using System. Collections. Generic;

You can't define jumpmaterial, must be an error
