How do I get the speed float to work in Unity?

Questions & Answers

I am new to unity and I am starting out by making a simple level in which you walk around in in first and third person. I am trying to animate the characters idle and walking am having trouble. Everything works fine including the transition from idle to walk until I change the exit time float to a speed float. I added the speed float and ordered it to transition from idle to walk if the speed is greater than 0.1. When I do that and play the walking animation never happens and I glide around in the idle animation. Does anyone know what I can change to fix this problem?

You have to forward the current speed/velocity to your Animator speed value. Get the Animator on Start or set a reference to the public member.

public Animator mAnimator;
Rigidbody mBody;

void Start()
{
    mBody = GetComponent<Rigidbody>();
}

void Update()
{
    mAnimator.SetFloat("MySpeed", mBody.velocity.magnitude);
}

I assume the problem is that you are not setting the speed value anywhere. A simple way to do that would be to code a script that access the animator’s speed variable.

GetComponent<Animator>().SetFloat("Speed", 1);

using UnityEngine;
using System.Collections;

public class PlayerMovement : MonoBehaviour {

float speed = 10f;
Vector3 direction = Vector3.zero;

CharacterController cc;

// Use this for initialization
void Start () {
	cc = GetComponent<CharacterController>();
}

// Update is called once per frame
void Update () {
	direction = transform.rotation * new Vector3( Input.GetAxis ("Horizontal") , 0, Input.GetAxis ("Vertical") ).normalized;
}

void FixedUpdate () {
	cc.SimpleMove(direction * speed); 

}

}

This is my player movement script. Can you edit my code to get it to do what you’re saying?
