Hello!
My aim is to have different footstep sounds depending on the ground the player is walking on. The over all structure is this:
variable to determine if the player is walking, raycast down if player is walking to determine what ground he/she is on, play an audio clip depending on the tag.
I have this script so far, but I get the error "Object reference not set to an instance of an object?".. What is the problem here? I am not very experienced with raycasting unfortunately, haha.
var snow : AudioClip;
var metal : AudioClip;
var walking : boolean;
var hit : RaycastHit;
var rayHit : boolean;
function Update()
{
var dwn = transform.TransformDirection (-Vector3.up);
if(Input.GetKeyDown("w") || Input.GetKeyDown("a") || Input.GetKeyDown("s") || Input.GetKeyDown("d"))
{
walking = true;
}
else if (Input.GetKeyUp("w") || Input.GetKeyUp("a") || Input.GetKeyUp("s") || Input.GetKeyUp("d"))
{
walking = false;
}
if (walking&&Physics.Raycast (transform.position, dwn)&&hit.transform.gameObject.tag == "metalfloor")
{
audio.clip = metal;
audio.Play();
}
if (walking&&Physics.Raycast (transform.position, dwn)&&hit.transform.gameObject.tag == "snowfloor")
{
audio.clip = snow;
audio.Play();
}
}
Thanks for your time, you guys are great with questions :)
