How to find distance between a player an a wall

Hello everyone,
I'm trying to make a kind of system that when the player pushes a button, It gives him the distance from the object directly in front of him. I've got no idea where to start. Does anyone know I way I could possibly do this?

 

Hey Watermelon_Dev, You're probably looking for this: https://docs.unity3d.com/ScriptReference/RaycastHit-distance.html

You can create a ray and raycasthit variable, and use it in

Physics.Raycast

, as shown in the example at the link I provided.

It's good practice to make sure to do any Physics related functions in FixedUpdate(), so check for the player input in the Update() function(because FixedUpdate() isn't guaranteed to run every frame), and then perform the physics code in the FixedUpdate.
Hope this helps ya!

 

Thanks! I'll try it out!

 

This applies mostly to moving objects or applying forces. If you're just using a raycast to check a distance then it's cool to do so in Update(), since it's not changing any physics data, just querying it.

Plus, since this is to be displayed on the screen, you probably want it to be in sync with the most recently drawn frame, which FixedUpdate() may not be.

 

Interesting, I guess I never really considered them different; Makes sense though, thanks for the clarification.

 

I've just implemented it, and it works really well!
