On hover over object
I have a cool idea I am wanting to do but not sure how to do it. I the cube I have in my screen to rotate 90 degress when the mouse hovers over it. How would I start this? I have four different cubes I would like to do this. Each one only do it when I got over it.
Hi
you would create a script and attach it to all of the cubes.
In C# this would look something like this:
using UnityEngine; using System.Collections;
public class example : MonoBehaviour {
void OnMouseEnter() {
transform.Rotate(Vector3.up * 90); // or whatever roatation you want
}
// to reset:
void OnMouseExit() {
transform.Rotate(*your inverse rotation*);
}
}
hope it helps

over time:
void OnMouseOver() {
Vector3 rotation = transform.rotation.eulerAngles;
if(rotation.y < 90)
rotation += new Vector3(0, rotation.y + 90 * Time.deltaTime, 0);
transform.eulerAngles = rotation;
}
try this, it will rotate your object 90 degrees in one second. If you want it slower, decrease the angles. I didn't test it ;)
Wouldn't On$$anonymous$$ouseOver continue to rotate the screen every frame? Also, depending on @davidflynn2's desired interaction, it might be useful to rotate gradually, rather than jumping 90 degrees in a single frame.
yes indeed, I edited it to On$$anonymous$$ouseEnter. He didn't say he want it to rotate gradually so I just answered what I thought he want :) but you're right, it would probably look better.
Yes that does what I want what would I have to change to make it happen over time that might improve what im looking at?
I tired adding "* Time.deltaTime" but it don't rotate all the way around then.
I edited my answer. You need to set it to On$$anonymous$$ouseOver so that it runs every frame. And then you have to check if it already is 90 degrees.
It sounds like you need to get more familiar with performing actions on hover and rotating the camera/screen. OnMouseOver is the method that gets called on every frame that the mouse is over a collider, and OnMouseEnter is a method that is called when the mouse first enters a collider. Camera.main accesses your main camera, and from there you can manipulate it's transform (including rotation).
