i have a cube that flips around only 90 degrees on every key press (up, down, left,right), i want to make the cube move only on two direction (forward and back) and i want to assign the movement on GetMouseButtonDown(0). when i press left button on mouse i want the cube flips forward without stopping than when i press left button on mouse again i want the cube flips backward with nonstop again. so far i have the code that makes the cube flip only 90degrees. can you help me with this pls?
using UnityEngine;
using System.Collections;
public class Cube : MonoBehaviour
{
public float tumblingDuration = 0.2f;
void Update()
{
var dir = Vector3.zero;
if (Input.GetKey(KeyCode.UpArrow))
dir = Vector3.forward;
if (Input.GetKey(KeyCode.DownArrow))
dir = Vector3.back;
if (Input.GetKey(KeyCode.LeftArrow))
dir = Vector3.left;
if (Input.GetKey(KeyCode.RightArrow))
dir = Vector3.right;
if (dir != Vector3.zero && !isTumbling)
{
StartCoroutine(Tumble(dir));
}
}
bool isTumbling = false;
IEnumerator Tumble(Vector3 direction)
{
isTumbling = true;
var rotAxis = Vector3.Cross(Vector3.up, direction);
var pivot = (transform.position + Vector3.down * 0.5f) + direction * 0.5f;
var startRotation = transform.rotation;
var endRotation = Quaternion.AngleAxis(90.0f, rotAxis) * startRotation;
var startPosition = transform.position;
var endPosition = transform.position + direction;
var rotSpeed = 90.0f / tumblingDuration;
var t = 0.0f;
while (t < tumblingDuration)
{
t += Time.deltaTime;
if( t < tumblingDuration)
{
transform.RotateAround(pivot, rotAxis, rotSpeed * Time.deltaTime);
yield return null;
}
else
{
transform.rotation = endRotation;
transform.position = endPosition;
}
}
isTumbling = false;
}
}
