How do I measure the velocity of object in Z-direction?
I am new to unity.
I have made a bicycle moving and I am putting a speedometer for that. The idea I used is detecting the velocity of an object and transfer it into angular movement. But the problem is that the speedometer is detecting the direction in Y-Direction (Like if I remove the gravity from rigid body, the bicycle goes downward and the speedometer is showing the speed). Here I want to measure the velocity of bicycle win Z-Direction.
Here I am adding two scripts which I used for Bicycle to move and another one for speedometer I put in.
Please help me through this.
Thank You
C# Script : Bicycle using System.Collections; using System.Collections.Generic; using UnityEngine;
public class PlayerFinalDuplicate_2 : MonoBehaviour {
public Animator anim;
Rigidbody rb;
public float speed = 50f;
public float rotationSpeed = 180f;
public float translationRate = 10f;
private bool run;
private float inputH;
private float inputV;
private string m_MovementAxisName;
private string m_TurnAxisName;
private float m_MovementInputValue;
private float m_TurnInputValue;
private void OnEnable ()
{
m_MovementInputValue = 0f;
m_TurnInputValue = 0f;
}
// Use this for initialization
void Start ()
{
anim = GetComponent<Animator>();
rb = this.GetComponent<Rigidbody>();
run = false;
m_MovementAxisName = "Vertical";
m_TurnAxisName = "Horizontal";
}
// Update is called once per frame
private void Update()
{
if (Input.GetKey (KeyCode.LeftShift)) {
run = true;
} else {
run = false;
}
inputH = Input.GetAxis ("Horizontal");
inputV = Input.GetAxis ("Vertical");
anim.SetFloat ("inputH", inputH);
anim.SetFloat ("inputV", inputV);
anim.SetBool ("run", run);
float moveX = inputH * speed * Time.deltaTime;
float moveZ = inputV * speed * Time.deltaTime;
if (moveZ <= 0f) {
moveX = 0f;
} else if (run) {
moveX *= 2f;
moveZ *= 2f;
}
float translation = Input.GetAxis ("Vertical") * speed;
translation *= Time.deltaTime;
rb.AddForce (this.transform.forward * -translation*translationRate);
// Store the player's input and make sure the audio for the engine is playing.
m_MovementInputValue = Input.GetAxis (m_MovementAxisName);
m_TurnInputValue = Input.GetAxis (m_TurnAxisName);
}
private void FixedUpdate()
{
// Move and turn.
//Move ();
Turn();
}
private void Turn()
{
// Adjust the rotation of the tank based on the player's input.
float turn = m_TurnInputValue * rotationSpeed * Time.deltaTime;
Quaternion turnRotation = Quaternion.Euler (0f, turn, 0f);
rb.MoveRotation (rb.rotation * turnRotation);
}
}
C# Script : Speedometer
Here I set the the image filling for measuring the velocity.
using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;
public class SpeedImage : MonoBehaviour { public Rigidbody rb; // HERE I NEED TO DROP THE BICYCLE OBJECT FROM THE HIERARCHY IN THE INSPECTOR BY SELECTING THE IMAGE FROM CANVAS I ADDED. public float minVelocity = 0.0f; public float maxVelocity = 10.0f;
private Image image;
// Use this for initialization
void Start ()
{
image = GetComponent<Image>();
}
// Update is called once per frame
void Update ()
{
image.fillAmount = rb.velocity.magnitude/maxVelocity;
}
}
