Trying to set object starting position and set range of movement

I am trying to find the starting position of my space ship and set the range of y movement

But I am getting series of errors when i do when saving the initial position - see attached

Thank you

Code (CSharp):

1.  
2. //speed of the enemy
3. public float speed = 3f;
4.  
5. //range of movement Y
6. public float rangeY = 2;
7.  
8. //initial position
9. Vector3 initialPos;
10.  
11. //direction
12. int direction = 1;
13.  
14. //save initial position
15. initialPos = transform.position;
16.  
17. //how much are we moving?
18. //Time.deltaTime, speed
19. float movementY = speed * Time.deltaTime * direction;
20.  
21. //new position
22. float newY = transform.posititon.y + movementY;
23.  
24. //checking whether we've left our range
25. if(Mathf.Abs(newY - initialPos.y) > rangeY)
26. {
27.     direction *= -1;
28. }
29. //if we can move further, let's move further
30. else
31. {
32.     transform.position += new Vector3(0, movementY, 0);
33. }
34. }

85. {
86.     direction *= -1;
87. }
88. //if we can move further, let's move further
89. else
90. {
91.     transform.position += new Vector3(0, movementY, 0);
92. }
93. }
94.  

 

Your code isn't inside any functions (or classes)?

 

I think you should do acourse on C#. I recommand checking out the website SoloLearn.
