problem of the Blend Tree

Hello to all


I have a problem with my 3D character with




here is the code

Code (CSharp):

1. [SerializeField] float speed;
2.    Animator anim ;
3.  
4.  
5. void Start () {
6.        anim = GetComponent<Animator> ();
7.    }
8.  
9.  
10.    void Update () {
11.  
12.        float forward = Input.GetAxis ("Vertical");
13.        float back = Input.GetAxis ("Vertical");
14.        anim.SetFloat ("Walk", forward);
15.            anim.SetFloat ("WalkBack", back);
16.        transform.Translate (Vector3.forward * forward * speed * Time.deltaTime);
17.        transform.Translate (Vector3.forward * back * -speed * Time.deltaTime);
18. }

when I make my character walk my floats are set to the same value



which makes my character bug in the animation of the transition, I want my character to respect the direction of my two animations

 

You are blending so you should only be using one value, such as "Walk". It would go from -1 to 1. 0 would be your 'Idle' animation, so you don't need to transition to that with a condition.

 

I realized what you suggested, but my character is back to 0





he doesn't realize -1 direction when I release my Input , he doesn't respect my direction of my WalkBack animation










I have the animations of Mixamo so I invert the basic value 180 of rotation for BlendTree

 

The graph should be Blend Type: 1D using the Walk parameter.

I don't know about the direction. You want it to turn around? It might be easier to rotate the model with code.

 

thank you for your message

I need 4 animation + Idle in my case, I use 2 to solve this problem gradually

because I use a Script of Third Person Camera Controller Movement as this case if

if you can throw me a C# example for the rotation or some specific solution

 

I just actually stumbled across this issue. I have a very simple 1D blend tree for movement forwards and backwards. A moveSpeed float was used to control the blend. My walk backwards animation comes in at -0.05f and there are various speeds until we get to a backwards run at -1.5f, but during runtime, all backwards animations completely freeze even though the blend tree animation window was highlighting the correct motions and showing the correct moveSpeed. However, in the inspector animation preview it appeared to be fine while not in runtime.

Anyhow, A fairly trivial fix was just to create a new blend tree for backwards motion using positive values and a flag to determine if we're in backwards mode or forwards, but this feels like I had to hack around it. Seems like Unity doesn't like the negative values in blend trees
