Hi there guys, quick question… Any tutorials or examples out there on how to add footstep sounds to… say the standard character contller? Or attached on an outside script would also work.
Characters definitely need footstep sounds 
What i did was to add a animation event when the foot is grounded. You have to double the walk animation for that so that you can edit the animation. The original animation is usually not editable. The copy is. And then you need to apply the copy to the character too. And use this copy then for your walk animations.
Then add a script to the character to play the sound fx. You have to add the samples in the edtor:
Thats what i use here. Its a JS snippet. In the inspector you have to add :
var SFXstep_left: AudioClip; //here you drop your sound fx
var SFXstep_right: AudioClip; // here you drop your sound fx
var level : float = 0.5; // This is how loud the sound plays
function WalkSoundLeft(){
AudioSource.PlayClipAtPoint ( SFXstep_left, transform.position,level); //plays the sound when the function is called
}
function WalkSoundRight(){
AudioSource.PlayClipAtPoint ( SFXstep_right, transform.position,level); //plays the sound when the function is called
}
And when done you open the animation editor and add an animation event to call the two loops in this script here where the foot is grounded.
Hope the description makes sense to you

thank you! There’s also a very nice footstep controller in the bootcamp demo I totally forgot about. It’s based on the movement of the character controller, and even has different sounds for different physics materials.
well I can’t get the footstep sound controller from bootcampt to work anywhere outside of bootcamp…
public var footAudioSource : AudioSource;
public var woodSteps : AudioClip[];
public var metalSteps : AudioClip[];
public var concreteSteps : AudioClip[];
public var sandSteps : AudioClip[];
private var cc : CharacterController;
private var t : Transform;
public var hitLayer : LayerMask;
private var cTag : String;
function Start()
{
cc = GetComponent(CharacterController);
t = transform;
}
function OnFootStrike ()
{
if(Time.time < 0.5) return;
if(cc != null)
{
volume = Mathf.Clamp01(0.1 + cc.velocity.magnitude * 0.3);
}
else
{
volume = 1;
}
footAudioSource.PlayOneShot(GetAudio(), volume);
}
function GetAudio() : AudioClip
{
var hit : RaycastHit;
//Debug.DrawRay(t.position + new Vector3(0, 0.5, 0), -Vector3.up * 5.0);
if(Physics.Raycast(t.position + new Vector3(0, 0.5, 0), -Vector3.up, hit, Mathf.Infinity, hitLayer))
{
cTag = hit.collider.tag.ToLower();
}
if(cTag == "wood")
{
return woodSteps[Random.Range(0, woodSteps.length)];
}
else if(cTag == "metal")
{
return metalSteps[Random.Range(0, metalSteps.length)];
}
else if(cTag == "concrete")
{
volume = 0.8;
return concreteSteps[Random.Range(0, concreteSteps.length)];
}
else if(cTag == "dirt")
{
volume = 1.0;
return sandSteps[Random.Range(0, sandSteps.length)];
}
else if(cTag == "sand")
{
volume = 1.0;
return sandSteps[Random.Range(0, sandSteps.length)];
}
else
{
volume = 1.0;
return sandSteps[Random.Range(0, sandSteps.length)];
}
}
I just want a simple script… nothing complicated, i don’t need to be checking for animation events or physics events… i just want footstep sounds to be played if the character controller is moving.
that’s all. not looking for an advanced footstep sound controller. something simple will serve me well
Didn`t i already give such a simple script and method? I´m pretty sure i did.
well yes except for editing the animation and adding events to the footsteps. that’s not all that easy honestly. i copied the animation, and the copy is still not editable.
that and i don’t animate, and have never messed with it really.
and also. unknown identifier “movement”
is that the animation event I am to make… no idea how to do that.
Haha, didnt notice that the movement stuff was still inside. Just remove those lines. Thats a restriction for my own needs. I fixed the script above …
And my fault. My description wasn`t clear enough it seems. Someting that can easily be fixed too. I hope the following explanation is of use for you
- First you need to double the animation. This works with ctrl+d. There`s unfortunately no menu item in the right click menu for that. I still wonder why …
- Rename the created animation. It`s confusing to have two walking animations with the same name. I´ve called it walkinged here for walking_editable.
- Then you need to add this doubled animation to your character. Increase the number of animations and drop the duplicated animation into the new slot.
- Open up the Animation Editor with your character selected. Choose your new created animation in the list. You may notice that all other animations here have a (Read Only) note behind their names. Our duplicated animation has not. It is editable
- When not done yet, drop the script with the sound fx functions to the character. We need to have access to the functions now.
- Right click at the keyframe are to add an animation event.
- Left click at it to open a little window where you can choose the function that you want to call. That`s why we have attached the soundfx script to our character. You can choose the function now from a drop down list.
And now it should call this function every time the animation is playing and reaches the point where you have added the animation event. In our case to play a sound effect.
Final step is of course to work with this edited walking animation now. The original walking animation doesn`t have this animation events.
Sorry for the wrong order of the pictures. I gave up at it …
