How can I toogle a bool with OnMouseOver() ?

In a 2D scene I have a Slider gameobject. I want to click and then drag it left to right. So I need some logic to set a bool to true when the mouse is hovering above, and false when its not.

Code (CSharp):

1. public bool mouseOverButton;
2.  
3. void OnMouseOver()
4.     {
5.         mouseOverButton = true;
6.     }

This will set my boolean to true when I hover over it.

How do I make it false now when the Mouseposition is outside the Slider Collider?
Also, I have 6 Sliders in total in my Scene. Do I have to worry about perfomance if I use many Instances of this script?
Thanks in advance .

 

OnMouseExit.

But I you are using a slider, better choices would be implementing the EventSystems interfaces for pointer enter and pointer exit.

 

Thank you,

it works with the OnMouseExit. I will look into the EventSystems later and try to implement it as I am not familiar with it.

 

Code (CSharp):

1. bool clicked;
2.  
3. void OnMouseOver()
4.     {
5.  
6.         if (Input.GetMouseButtonDown (0)) {
7.             clicked = true;
8.         }
9.  
10.     }
11.  
12. void Update () {
13.         if (Input.GetMouseButtonUp (0)) {
14.             clicked = false;
15.         }
16.         if (clicked){
17.             transform.position = slider;
18.         }

(Vector3 slider is translated with ScreenToWorldSpace and only x value gets updated to move left&right)

This is my solution for now. It is weird code, but gets the job done. When I click on slider, it will follow my Mouse. With OnMouseExit i run into the problem that when i moved the mousepointer to fast or up and down it would stop moving and not feel like a slider.
