confused.png Hello i saw the mecanim animation tutorial by unity and get to know abt it. So i made my own scene and made a controller with a new player using the same script from unity. I used new animation files from the 150 animation which unity gave for free.

Here is the script

 

 

c#

using UnityEngine;

using System.Collections;

 

// Require these components when using this script

[RequireComponent(typeof (Animator))]

[RequireComponent(typeof (CapsuleCollider))]

[RequireComponent(typeof (Rigidbody))]

public class BotControlScript : MonoBehaviour

{

    [System.NonSerialized]                  

    public float lookWeight;                    // the amount to transition when using head look

    

    [System.NonSerialized]

    public Transform enemy;                     // a transform to Lerp the camera to during head look

    

    public float animSpeed = 1.5f;              // a public setting for overall animator animation speed

    public float lookSmoother = 3f;             // a smoothing setting for camera motion

    public bool useCurves;                      // a setting for teaching purposes to show use of curves

 

    

    private Animator anim;                          // a reference to the animator on the character

    private AnimatorStateInfo currentBaseState;         // a reference to the current state of the animator, used for base layer

    private AnimatorStateInfo layer2CurrentState;   // a reference to the current state of the animator, used for layer 2

    private CapsuleCollider col;                    // a reference to the capsule collider of the character

    

 

    static int idleState = Animator.StringToHash("Base Layer.Idle");    

    static int locoState = Animator.StringToHash("Base Layer.Locomotion");          // these integers are references to our animator's states

    static int jumpState = Animator.StringToHash("Base Layer.Jump");                // and are used to check state for various actions to occur

    static int jumpDownState = Animator.StringToHash("Base Layer.JumpDown");        // within our FixedUpdate() function below

    static int fallState = Animator.StringToHash("Base Layer.Fall");

    static int rollState = Animator.StringToHash("Base Layer.Roll");

    static int waveState = Animator.StringToHash("Layer2.Wave");

    

 

    void Start ()

    {

        // initialising reference variables

        anim = GetComponent<Animator>();                      

        col = GetComponent<CapsuleCollider>();              

        enemy = GameObject.Find("Enemy").transform; 

        if(anim.layerCount ==2)

            anim.SetLayerWeight(1, 1);

    }

    

    

    void FixedUpdate ()

    {

        float h = Input.GetAxis("Horizontal");              // setup h variable as our horizontal input axis

        float v = Input.GetAxis("Vertical");                // setup v variables as our vertical input axis

        anim.SetFloat("Speed", v);                          // set our animator's float parameter 'Speed' equal to the vertical input axis              

        anim.SetFloat("Direction", h);                      // set our animator's float parameter 'Direction' equal to the horizontal input axis        

        anim.speed = animSpeed;                             // set the speed of our animator to the public variable 'animSpeed'

        anim.SetLookAtWeight(lookWeight);                   // set the Look At Weight - amount to use look at IK vs using the head's animation

        currentBaseState = anim.GetCurrentAnimatorStateInfo(0); // set our currentState variable to the current state of the Base Layer (0) of animation

        

        if(anim.layerCount ==2)     

            layer2CurrentState = anim.GetCurrentAnimatorStateInfo(1);   // set our layer2CurrentState variable to the current state of the second Layer (1) of animation

        

        

        // LOOK AT ENEMY

        

        // if we hold Alt..

        if(Input.GetButton("Fire2"))

        {

            // ...set a position to look at with the head, and use Lerp to smooth the look weight from animation to IK (see line 54)

            anim.SetLookAtPosition(enemy.position);

            lookWeight = Mathf.Lerp(lookWeight,1f,Time.deltaTime*lookSmoother);

        }

        // else, return to using animation for the head by lerping back to 0 for look at weight

        else

        {

            lookWeight = Mathf.Lerp(lookWeight,0f,Time.deltaTime*lookSmoother);

        }

        

        // STANDARD JUMPING

        

        // if we are currently in a state called Locomotion (see line 25), then allow Jump input (Space) to set the Jump bool parameter in the Animator to true

        if (currentBaseState.nameHash == locoState)

        {

            if(Input.GetButtonDown("Jump"))

            {

                anim.SetBool("Jump", true);

            }

        }

        

        // if we are in the jumping state... 

        else if(currentBaseState.nameHash == jumpState)

        {

            //  ..and not still in transition..

            if(!anim.IsInTransition(0))

            {

                if(useCurves)

                    // ..set the collider height to a float curve in the clip called ColliderHeight

                    col.height = anim.GetFloat("ColliderHeight");

                

                // reset the Jump bool so we can jump again, and so that the state does not loop 

                anim.SetBool("Jump", false);

            }

            

            // Raycast down from the center of the character.. 

            Ray ray = new Ray(transform.position + Vector3.up, -Vector3.up);

            RaycastHit hitInfo = new RaycastHit();

            

            if (Physics.Raycast(ray, out hitInfo))

            {

                // ..if distance to the ground is more than 1.75, use Match Target

                if (hitInfo.distance > 1.75f)

                {

                    

                    // MatchTarget allows us to take over animation and smoothly transition our character towards a location - the hit point from the ray.

                    // Here we're telling the Root of the character to only be influenced on the Y axis (MatchTargetWeightMask) and only occur between 0.35 and 0.5

                    // of the timeline of our animation clip

                    anim.MatchTarget(hitInfo.point, Quaternion.identity, AvatarTarget.Root, new MatchTargetWeightMask(new Vector3(0, 1, 0), 0), 0.35f, 0.5f);

                }

            }

        }

        

        

        // JUMP DOWN AND ROLL 

        

        // if we are jumping down, set our Collider's Y position to the float curve from the animation clip - 

        // this is a slight lowering so that the collider hits the floor as the character extends his legs

        else if (currentBaseState.nameHash == jumpDownState)

        {

            col.center = new Vector3(0, anim.GetFloat("ColliderY"), 0);

        }

        

        // if we are falling, set our Grounded boolean to true when our character's root 

        // position is less that 0.6, this allows us to transition from fall into roll and run

        // we then set the Collider's Height equal to the float curve from the animation clip

        else if (currentBaseState.nameHash == fallState)

        {

            col.height = anim.GetFloat("ColliderHeight");

        }

        

        // if we are in the roll state and not in transition, set Collider Height to the float curve from the animation clip 

        // this ensures we are in a short spherical capsule height during the roll, so we can smash through the lower

        // boxes, and then extends the collider as we come out of the roll

        // we also moderate the Y position of the collider using another of these curves on line 128

        else if (currentBaseState.nameHash == rollState)

        {

            if(!anim.IsInTransition(0))

            {

                if(useCurves)

                    col.height = anim.GetFloat("ColliderHeight");

                

                col.center = new Vector3(0, anim.GetFloat("ColliderY"), 0);

                

            }

        }

        // IDLE

        

        // check if we are at idle, if so, let us Wave!

        else if (currentBaseState.nameHash == idleState)

        {

            if(Input.GetButtonUp("Jump"))

            {

                anim.SetBool("Wave", true);

            }

        }

        // if we enter the waving state, reset the bool to let us wave again in future

        if(layer2CurrentState.nameHash == waveState)

        {

            anim.SetBool("Wave", false);

        }

    }

}

 

And all of them worked correctly with moving forward back. I arranged them made it settings and everything. But when i do for jump, it jumps correctly and continue to jump when i press up button. But when i replace it with my old jump file using the sme pace and position it jumps correctly. I know that i missed one setting between that two files. Below in the attachment i have added those two fbx files, please anyone see it and say what I did wrong, if you want more files including the controllers

You are probably looping they jump animation (plays until it you let go of the button) while your old jump animation is set to not loop (so it only plays only once per button press). Check out this page for some help. As far as the script goes, it looks fine (then again, I have only a little experience using Unity3D).

Hmmm... Does it only not work when you play the jumping animation? Can you test it on different animation?

 

As far as the script is concerned, try changing the if loop that checks for the jump button press to a while loop.

I just tested it out and I don't see any looping (even when a run and jump into mid-air).
