Movement, rotate with GUI button. Half working?

Hi guys, I am trying to make a simple 2D game but have gotten stumped on a what I thought would be a simple movement code.

For the movement code, it has 2 buttons, an up and a down button. The hero is always moving forward, and the buttons change the direction.

Where I am having my trouble is, the down works fine, but the up button instantly raises it to 9.99999 and does nothing else. Is there another way to do this that I am missing?

I am also having trouble with an "if" state for it to only work from 0 to -90 and 0 to 90 degrees each button so it cant move backwards.

I thought this would of worked

Code (csharp):

1. if (heroObject.Rigidbody2D.rotation <90)
2. {
3. }

but it is saying I'm not referencing to a state of an object (Which I assume is the "Rotation").
Could I please be pointed in the right direction for this also?

My code is:

Code (csharp):

1.  
2. var spinSpeed : float = 1; //speed which the object will spin
3. var forwardVelocityValue : float = 2; //speed the object will move forward
4. var heroObject : GameObject; //the object this script applies to
5.  
6.  
7. function OnGUI ()
8. {
9.     GUI.Box (Rect (10,10,100,90), "Movement"); //draw a box around the buttons
10.  
11.     if (GUI.RepeatButton (Rect (20,40,80,20), "Up")) //spin up button
12.     {
13.         heroObject.transform.eulerAngles.z= spinSpeed; //Object to spin.Startspinning.angle.z = spin speed
14.     }
15.  
16.     if (GUI.RepeatButton (Rect (20,70,80,20), "Down"))//spin down button
17.     {
18.         heroObject.transform.eulerAngles.z-= spinSpeed;//Object to spin.Startspinning.angle.z- = spin speed
19.     }
20. }
21.  
22.  
23. function FixedUpdate()
24. {
25.     rigidbody2D.velocity = transform.right * forwardVelocityValue;;//object to move.velocity = speed (x,y,)
26. }

 

I have managed to find a way to get it to work.

If it helps anyone, feel free to use it or what ever.

Code (csharp):

1.  var spinSpeed : float = 1; //speed which the object will spin
2. var forwardVelocityValue : float = 2; //speed the object will move forward
3. var heroObject : GameObject; //the object this script applies to
4. var maximumUpRotation : float = 80;//The maximum rotation for the Up button to work
5. var minimumUpRotation : float = 275;//The minimum rotation for the Up button to work
6. var maximumDownRotation : float = 280;//The maximum rotation for the Down button to work
7. var minimumDownRotation : float = 85;//The minimum rotation for the Down button to work
8.  
9.  
10. function OnGUI ()
11. {
12.     GUI.Box (Rect (10,10,100,90), "Movement"); //draw a box around the buttons
13.  
14.     if (GUI.RepeatButton (Rect (20,40,80,20), "Up")) //spin up button
15.     {
16.         if (transform.localEulerAngles.z < maximumUpRotation) //if rotation is 80 or less then do
17.         {
18.             heroObject.transform.Rotate(0,0,spinSpeed);//Object to spin.Startspinning.angle.z
19.         }
20.         if (transform.localEulerAngles.z > minimumUpRotation) //if rotation is 255 or more then do
21.         {
22.             heroObject.transform.Rotate(0,0,spinSpeed);//Object to spin.Startspinning.angle.z
23.         }
24.     }
25.  
26.     if (GUI.RepeatButton (Rect (20,70,80,20), "Down"))//spin down button
27.     {
28.         if (transform.localEulerAngles.z < minimumDownRotation) //if rotation is 85 or less then do
29.         {
30.             heroObject.transform.Rotate(0,0,-spinSpeed);//Object to spin.Startspinning.angle.-z
31.            
32.         }
33.         if (transform.localEulerAngles.z > maximumDownRotation) //if rotation is 250 or more then do
34.         {
35.             heroObject.transform.Rotate(0,0,-spinSpeed);//Object to spin.Startspinning.angle.-z
36.         }
37.     }
38. }
39.  
40.  
41. function FixedUpdate()
42. {
43.     rigidbody2D.velocity = transform.right * forwardVelocityValue;//object to move.velocity = speed (x,y)
44. }
