Cursor Toggle in Menu (UI)

Questions & Answers

Hi guys! So this is my first time in this forum, and my first time learning Unity and programming in general. Currently I’m creating a simple UI for one of my passion projects and it consists of a Main Menu.

Here’s a screenshot:

So, what I want is is for that little cursor or pointer to move up and down whenever I highlight the menu items. I would be fine if the information you give me is just the general gist and I’ll just continue from there, but I’m also not opposed to specific info.

Thank you in advance guys!

Note: This may be asked already in the past but I don’t know the correct keywords to use while searching so I just decided on making my own question instead.

Okay. If you want its position to be in line with New Game, Settings and Quit, then first you need to know what positions those are. Since you’re using a menu here, you can either decide to hard code these or create multiple variables for each. Something like:

public Vector3 position1;
public Vector3 position2;
public Vector3 position3;
public transform myCursor;

After you know where each position is (move it in the editor maybe.) Then you need to detect if the mouse is over it. You can do this in two ways depending on your implementation.

  1. If you are using 3D texts or other objects that have a collider, then using a camera ray is your move.

     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
 RaycastHit hit;
 if (Physics.Raycast(ray, out hit)){
     if (hit.transform.name == "Button_NewGame"){
          myCursor.position = position1;
     }
 }

  2. If you are using GUI elements like GUI.Label you’ll have to create a rect at the mouse position, and a rect for the text (that you use to display it.) and use something like Rect.Overlaps

    void OnGUI(){
    Rect newgameRect = new Rect(100,300,500,50);
    GUI.Label(“New Game”,newgameRect);

     Vector3 mousePos = Input.mousePosition;
 Rect mouseRect = new Rect(mousePos.x, mousePos.y, 5,5);

 if (mouseRect.Overlaps(newgameRect){
     myCursor.position = position1;
 }

    }
