Footsteps in different Terrains FMOD - calling parameters issue

Unity Engine

Hi, I’m having issues with my attempt to implement footsteps for different terrains using Unity and FMOD. The footsteps are triggered by animation events, but I can hear only one kind of terrain when playing. I guess there’s something wrong with the script that is not changing the parameters in FMOD.

Here’s the script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerFootsteps : MonoBehaviour {

    private enum CURRENT_TERRAIN { GRASS, GRAVEL, WOOD_FLOOR, WATER };

    [SerializeField]
    private CURRENT_TERRAIN currentTerrain;

    private FMOD.Studio.EventInstance foosteps;

    private void Update()
    {
        DetermineTerrain();
    }

    private void DetermineTerrain()
    {
        RaycastHit[] hit;

        hit = Physics.RaycastAll(transform.position, Vector3.down, 10.0f);

        foreach (RaycastHit rayhit in hit)
        {
            if (rayhit.transform.gameObject.layer == LayerMask.NameToLayer("Gravel"))
            {
                currentTerrain = CURRENT_TERRAIN.GRAVEL;
                break;
            }
            else if (rayhit.transform.gameObject.layer == LayerMask.NameToLayer("Wood"))
            {
                currentTerrain = CURRENT_TERRAIN.WOOD_FLOOR;
                break;
            }
            else if (rayhit.transform.gameObject.layer == LayerMask.NameToLayer("Grass"))
            {
                currentTerrain = CURRENT_TERRAIN.GRASS;
            }
            else if (rayhit.transform.gameObject.layer == LayerMask.NameToLayer("Water"))
            {
                currentTerrain = CURRENT_TERRAIN.WATER;
            }
        }
    }

    public void SelectAndPlayFootstep()
    {    
        switch (currentTerrain)
        {
            case CURRENT_TERRAIN.GRAVEL:
                PlayFootstep(1);
                break;

            case CURRENT_TERRAIN.GRASS:
                PlayFootstep(0);
                break;

            case CURRENT_TERRAIN.WOOD_FLOOR:
                PlayFootstep(2);
                break;

            case CURRENT_TERRAIN.WATER:
                PlayFootstep(3);
                break;

            default:
                PlayFootstep(0);
                break;
        }
    }

    private void PlayFootstep(int terrain)
    {
        foosteps = FMODUnity.RuntimeManager.CreateInstance("event:/Footsteps");
        foosteps.setParameterByName("Terrain", terrain);
        foosteps.set3DAttributes(FMODUnity.RuntimeUtils.To3DAttributes(gameObject));
        foosteps.start();
        foosteps.release();
    }
}

The ground objects are assigned to layers according to the script. But I can only hear the sounds coming from Parameter = 0 in the game, even though I’ve added different grounds in different layers. Is there something wrong with the code? I’m sound designer, I really can’t say if the code is ok.

I’m using FMOD 2.00.10 and Unity 2020.1.10

I recommend liberally sprinkling Debug.Log() statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

  • is this code even running? which parts are running? how often does it run?
  • what are the values of the variables involved? Are they initialized?

Knowing this information will help you reason about the behavior you are seeing.
