Movement, rotate with GUI button. Half working?

Unity Engine
1

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

if (heroObject.Rigidbody2D.rotation <90)
{
}

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:

var spinSpeed : float = 1; //speed which the object will spin
var forwardVelocityValue : float = 2; //speed the object will move forward
var heroObject : GameObject; //the object this script applies to


function OnGUI () 
{
	GUI.Box (Rect (10,10,100,90), "Movement"); //draw a box around the buttons

	if (GUI.RepeatButton (Rect (20,40,80,20), "Up")) //spin up button
	{
		heroObject.transform.eulerAngles.z= spinSpeed; //Object to spin.Startspinning.angle.z = spin speed
	}

	if (GUI.RepeatButton (Rect (20,70,80,20), "Down"))//spin down button
	{
		heroObject.transform.eulerAngles.z-= spinSpeed;//Object to spin.Startspinning.angle.z- = spin speed
	}
}


function FixedUpdate()
{
	rigidbody2D.velocity = transform.right * forwardVelocityValue;;//object to move.velocity = speed (x,y,)
}
2

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

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

 var spinSpeed : float = 1; //speed which the object will spin
var forwardVelocityValue : float = 2; //speed the object will move forward
var heroObject : GameObject; //the object this script applies to
var maximumUpRotation : float = 80;//The maximum rotation for the Up button to work
var minimumUpRotation : float = 275;//The minimum rotation for the Up button to work
var maximumDownRotation : float = 280;//The maximum rotation for the Down button to work
var minimumDownRotation : float = 85;//The minimum rotation for the Down button to work


function OnGUI () 
{
	GUI.Box (Rect (10,10,100,90), "Movement"); //draw a box around the buttons

	if (GUI.RepeatButton (Rect (20,40,80,20), "Up")) //spin up button
	{
		if (transform.localEulerAngles.z < maximumUpRotation) //if rotation is 80 or less then do
		{
			heroObject.transform.Rotate(0,0,spinSpeed);//Object to spin.Startspinning.angle.z
		} 
		if (transform.localEulerAngles.z > minimumUpRotation) //if rotation is 255 or more then do
		{
			heroObject.transform.Rotate(0,0,spinSpeed);//Object to spin.Startspinning.angle.z
		} 
	}

	if (GUI.RepeatButton (Rect (20,70,80,20), "Down"))//spin down button
	{
		if (transform.localEulerAngles.z < minimumDownRotation) //if rotation is 85 or less then do
		{
			heroObject.transform.Rotate(0,0,-spinSpeed);//Object to spin.Startspinning.angle.-z
			
		} 
		if (transform.localEulerAngles.z > maximumDownRotation) //if rotation is 250 or more then do
		{
			heroObject.transform.Rotate(0,0,-spinSpeed);//Object to spin.Startspinning.angle.-z
		} 
	}
}


function FixedUpdate()
{
	rigidbody2D.velocity = transform.right * forwardVelocityValue;//object to move.velocity = speed (x,y)
}
