Character not jumping

[vishnuluke]

I am making a colour splash game
But my character not jumping
In every game am making with unity not jumping
Codings are perfect

Is there any problems with unity

Please help me fast as you can guys.
I stoped working with unity because of this problem.
My last hope

the variable “rb” is never assigned in your code. add this to your code:

	void Start () {
		
		rb = GetComponent<Rigidbody> ();
	}
