EventTrigger Move issue

Im trying to track mouse move over some object in scene with EventTrigger component (all other events are work) but it does not work =( what i doing wrong, maybe i missed something?
(on my camera I've added physics raycaster, eventsystem, standalone input modul conponents.).

 

think i misunderstood what this event do. according to documentation it handles keyboard, not a mouse as i thought.
but anyway, i have no idea how to use this event, although it is sad that there no event for tracking mouse position change without any button down.
Project file? You mean sln?

 

actually no, i wanted to use this event for regular objects, but for this code thx.

 

oh no, i wanted to track mouse position when i hold button, think your code will help me with that.

 

thx. will try

 

Hey free code!

Vector3 localPos; // Mouse position

needs to be a Vector2, otherwise its an error.

 

It's also missing a semicolon at the end of line 28
But ignoring that, that's a great snippet, thanks!

 

Since this thread still comes up a lot when searching for "what the heck is this useless Move event in EventTrigger, and why can't I get a simple mouse-moved event?", here's my version (based on Karl's code above) that invokes an event whenever the mouse moves over a UI element.

Code (CSharp):

1. /* MouseMoveTrigger
2. Place this on a UI element that you want to cause mouse move events.
3. For example, it might be an Image (even with 0% opacity) behind all
4. your other UI elements, to send mouse events for your game.
5. */
6. using UnityEngine;
7. using UnityEngine.Events;
8. using UnityEngine.EventSystems;
9. using UnityEngine.UI;
10. using System.Collections;
11.  
12. public class MouseMoveTrigger: MonoBehaviour, IPointerEnterHandler, IPointerExitHandler {
13.    
14.     // Event invoked when the mouse moves over this UI element.
15.     public UnityEvent onMouseMove;
16.        
17.     // Called when the pointer enters our GUI component.
18.     // Start tracking the mouse
19.     public void OnPointerEnter( PointerEventData eventData ) {
20.         StartCoroutine("TrackPointer");
21.     }
22.    
23.     // Called when the pointer exits our GUI component.
24.     // Stop tracking the mouse
25.     public void OnPointerExit( PointerEventData eventData ) {
26.         StopCoroutine("TrackPointer");
27.     }
28.    
29.     IEnumerator TrackPointer() {
30.         Vector3 mousePos = Vector3.zero;
31.         while (Application.isPlaying) {
32.             if (Input.mousePosition != mousePos) {
33.                 if (onMouseMove != null) onMouseMove.Invoke();
34.                 mousePos = Input.mousePosition;
35.             }
36.             yield return 0;
37.         }
38.     }
39.  
40. }

 

Exactly what we need. Thank you @karl_jones for code and @JoeStrout for component
