Rotation script issue?
Hey guys, I am trying to make it so when I press A or D I start to rotate until I stop to press W(Forward) again...Not sure what I am doing wrong here...
if (Input.GetKey(KeyCode.A))
transform.Rotate(Vector3.up * speed * Time.deltaTime);
if (Input.GetKey(KeyCode.D))
transform.Rotate(-Vector3.up * speed * Time.deltaTime);
I have these both in the Update() function...Am I not calling them right? For our game I want it to be a smooth 60 degree turn every-time not sure how to do this or where to find out how...
Thanks!
What do you mean by 'until I stop to press W again'? This snippet doesn't include anything that checks the W key, so it's confusing what you're asking.
It's also unclear to me how you want to create a 60 degree turn with this...all you are doing here is checking if the key is down, and applying a rotation every frame. You aren't checking whether the rotation has gone over 60 degrees, or performing any rotations while the player is not holding down a button.
It sounds like what you want to do is create a coroutine to rotate the player when they press a button; so instead of
if (Input.GetKey(KeyCode.A))
transform.Rotate(Vector3.up * speed * Time.deltaTime);
you'd do something like
if (Input.GetKeyUp(KeyCode.A))
StartCoroutine(DoRotation());
...
IEnumerator DoRotation()
{
float angle = 0;
while(angle < 60)
{
a = rotationSpeed * Time.deltaTime;
transform.Rotate(a)
angle += a;
yield return new WaitForEndOfFrame();
}
}

In the future, you should also use a more descriptive title so other users who want to do this can find your answer. "Perform fixed rotation over time" or something that describes your goal. You should also include a description of the behavior you are currently seeing, compared to what you want so it's more clear what help you need.
It still didn't work, would I call the IEnumerator in the Awake() function? Then call the actually coroutine in the FixedUpdate()? I am trying to get it so when I press A or D it will keep rotating 60 degrees every frame until I stop pressing it ya know? So that way I only use W to move forward, I have my actual movement set up like this.
if ($$anonymous$$athf.Abs(forwardInput) > inputDel)
{
//move
rBody.velocity = transform.forward * forwardInput * ForwVel;
}
else
rBody.velocity = Vector3.zero;
}
P.S Sorry about the title / descriptor I am new to unity forums, thanks again.
So basically, I'm trying to create a movement script without using a RayCast because this is my first game. I'm trying to make it so when I use A or S I will rotate, but W will move me forward do you know what I mean? I think I meant 60 degrees to keep it a certain way, but trying to get so when I hit D or A I can keep hitting it until I am either forward, backward, left or right, then I can press W to move. Ya know?
Thanks again,
KRD
