Error CS0103?

the error is that you haven't provided a reference to CrossPlatformInput. where is it defined?

How do I use code tags? Is there a way to search the entire code to see where else CrossPlatformInput is defined?

using UnityEngine;

[RequireComponent(typeof(PlatformerCharacter2D))] public class Platformer2DUserControl : MonoBehaviour { private PlatformerCharacter2D character; private bool jump;

 void Awake()
 {
     character = GetComponent<PlatformerCharacter2D>();
 }
 
 void Update ()
 {
     // Read the jump input in Update so button presses aren't missed.
     #if CROSS_PLATFORM_INPUT
     if (CrossPlatformInput.GetButtonDown("Jump")) jump = true;
     #else
     if (Input.GetButtonDown("Jump")) jump = true;
     #endif
     
 }
 
 void FixedUpdate()
 {
     // Read the inputs.
     bool crouch = Input.GetKey(KeyCode.LeftControl);
     #if CROSS_PLATFORM_INPUT
     float h = CrossPlatformInput.GetAxis("Horizontal");
     #else
     float h = Input.GetAxis("Horizontal");
     #endif
     
     // Pass all parameters to the character control script.
     character.Move( h, crouch , jump );
     
     // Reset the jump input once it has been used.
     jump = false;
 }

}

Question, where does CrossPlatformInput refer to? I can't find it in the UnityReference.

You also define "float h" two times which I don't understand.

h is defined in a conditional, so only really once. it ain't pretty, but it'll work ;)

appreciate the help. i added the CrossPlatformInput from the sample assets and got the project functioning again!
