I’m trying to make footstep sounds based on the physical material type the player is stepping on using a line trace as described here:
That thread has been shut down by Staff saying it is an old post and much of the information may have changed. I’m still trying this line trace technique because I don’t see any updated posts about this.
So I have anim notifies when the characters foot touches the ground and I respond to those in my animation blueprint. First we do a line trace from the actor location into the ground. At the bottom right you see we call “Get Surface Type” and from there we are supposed to plug into a Select node (to choose the correct sound based on that surface type) and then into a PlaySound node.
But for testing purposes I am switching on the surface type and printing a debug message. The problem is that its not detecting the right surface type.
I added 2 new surface types in Project Settings > Physics. Then I created my Physical Materials for those by right clicking Physics > Physical Materials in the content browser and associating them with the surface types. Then I opened my Landscape Material and set the Physical Material and saved.
In my level editor I’ve clicked my sidewalk mesh and under Collision > Physical Material Override and set one of the physical materials I just created.
The problem is that it never returns the correct surface type. Where am I going wrong?
If there’s updated information on how to do this as the old post suggests, please include it here for people finding this post later on.
