How to turn camera 90 degrees smoothly?
Hello! So I'm super new to unity. I'm using some code I found in a tutorial to make the camera rotate with swipe gestures via a Leap Motion. However, the code makes the camera rotate continuously without stopping. How would I get it to rotate smoothly 90 degrees per swipe gesture? (Note: the camera is being assigned to the name blockOne. It was just a placeholder from the tutorial)
using UnityEngine;
using System.Collections;
using Leap;
public class GestureHands : MonoBehaviour
{
Controller controller;
public GameObject blockOne;
public bool spinLeft;
public bool spinRight;
void Start()
{
controller = new Controller();
controller.EnableGesture(Gesture.GestureType.TYPESWIPE);
controller.Config.SetFloat("Gesture.Swipe.MinLength", 100.0f);
controller.Config.SetFloat("Gesture.Swipe.MinVelocity", 150f);
controller.Config.Save();
}
void Update()
{
Frame frame = controller.Frame();
GestureList gestures = frame.Gestures();
Hand hand = frame.Hands.Frontmost;
if (hand.IsRight)
{
for (int i = 0; i < gestures.Count; i++)
{
Gesture gesture = gestures[i];
if (gesture.Type == Gesture.GestureType.TYPESWIPE)
{
SwipeGesture Swipe = new SwipeGesture(gesture);
Vector swipeDirection = Swipe.Direction;
if (swipeDirection.x < 0)
{
Debug.Log("Left");
spinLeft = true;
spinRight = false;
}
else if (swipeDirection.x > 0)
{
Debug.Log("Right");
spinRight = true;
spinLeft = false;
}
}
}
if (spinLeft == true)
{
blockOne.transform.Rotate(Vector3.down, 45 * Time.deltaTime);
}
if (spinRight == true)
{
blockOne.transform.Rotate(Vector3.up, 45 * Time.deltaTime);
}
}
}
}
Hi @IxiArcana - Doing a similar thing to you. Originally i used an IEnumerator to create a time delay after which id falsify the bool that makes the camera rotate: http://docs.unity3d.com/ScriptReference/MonoBehaviour.StartCoroutine.html
However this led to a major bug with the way the swipe gesture works so id recomend an alternative approach:
-Set the camera to 'LookAt' a target gameobject(make it empty/invisible) that moves to the new position when you perform a swipe. Im using a 'smoothLookAt' pre-built script for a smooth rotation effect. - When you swipe, call the command to re-position the target gameobject so the camera will rotate to look in the desired direction. - (apologies for messy script)
