I have a First Person Controller from the Unity Assets I imported. I’d like to know in C#, how to access the CharacterMotor Component’s ‘Max Forward Speed’ variable from another script, as well as change it…

using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour
{
	//Create a motor variable.
	CharacterMotor motor;

	//Create your own speed variable.
	float mfs;

	//For testing purposes
	string label;
	
	void Start ()
	{
		//Be sure component is found before assigning.
		if(GetComponent<CharacterMotor>())
			motor = GetComponent<CharacterMotor>();

		//Check if motor is null or not before matching your speed with motor's speed. 
		//If you want to create your own speed on startup, just assign a float or int to mfs and remove this.
		if(motor != null)
			mfs = motor.movement.maxForwardSpeed;
	}
	
	void Update()
	{
		//Press and hold up or down on vertical axis to increase and decrease speed.
		//For Testing Purposes.
		mfs += (int)Input.GetAxis ("Vertical");

		//Be sure motor is not null before matching motor's speed with your variable's speed.
		if(motor)
			motor.movement.maxForwardSpeed = mfs;

		//Update label at runtime to output GUI.
		//For Testing Purposes.
		label = "Motor Script Max Forward Speed = " + motor.movement.maxForwardSpeed + "

" + "Your Max Forward Speed = " + mfs;
}

	void OnGUI ()
	{
		//Print label variable.
		GUILayout.Label (label);

		//Instructions.
		GUILayout.Label("

" + “Press Up and Down Arrow keys (or W and S) to increase or decrease Max Forward Speed.”);
}
}
