I did the basic movement code and it was working fine, but i dont understand how to do the gravity and jumping. it says:  
**Gravity and Jumping**  
Next up we need jumping. This code will give you jumping; it would be inserted after the other key.isDown events  
i copied the code and did it in my char but when i test it, it says there are 3 errors!  
Tell me how do i have to do the code so it wont say errors!
