Animated Cursor on Click During Gameplay

sonicjoy

I'd like to have my circle cursor change to an "animated cursor" whenever the user clicks, then back to the circle cursor. I see how to change the cursor this with interactions on hotspots, but I'd like it to happen anywhere the user clicks on the scene. This is mainly because I'm making a touch-screen game and I'd like the user to know where they've tapped the screen.

Any suggestions on how to do this?

Welcome to the community, @sonicjoy.

Cursor animations can be set to play when hovering over interactive objects, but given the complexity of the different kinds of cursor "modes", and the fact that you're using touch-screen and not a "real" cursor - this is best left to a custom script.

Try this:

http://pasteall.org/987216/csharp

Paste it into a new C# script named AnimateOnTouch.cs, and attach it to an Image UI component on a UI Canvas in your scene.  The script will position this image at the cursor/touch position, and animate it whenever a touch is made.

This will be done by invoking a Trigger parameter on an Animator also attached to the Image - so you'll need to add that component, and create an Animator Controller that plays a "click" animation when the named Trigger parameter is invoked.

Thank you, Chris! I'm having a lot of fun making a game with Adventure Creator (and learning Unity concurrently!)

Does anyone have a working link to this script? The link in the post is no longer working unfortunately.

I want to play a short animation momentarily each time the player clicks anywhere on the screen and at the click location of the cursor. For example, a small ripple will appear when clicking on water or a puff of dust when clicking on ground.

Is there any way to achieve this with the AC engine or will I have to use a script like this? Thank you.

I'll paste the script below, but since the original post AC has a "Unity UI" option for cursor rendering at the top of the Cursor Manager.

With this option, the cursor is drawn using Unity UI components, which allow it to be controlled/modified through Animations that can be set to trigger when clicking.

See the Manual's "Unity UI Cursor rendering" chapter for more details.

AnimateOnTouch.cs:

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using AC;

public class AnimateOnTouch : MonoBehaviour
{

    public Animator _animator;
    public string clickEffectTrigger = "ClickEffect";
    public string clickIconInt = "IconID";
    private RectTransform rectTransform;


    private void Awake ()
    {
        rectTransform = _animator.GetComponent <RectTransform>();
    }


    private void Update ()
    {
        rectTransform.position = Input.mousePosition;

        if (Input.GetMouseButtonDown (0) && KickStarter.stateHandler.IsInGameplay ())
        {
            Hotspot activeHotspot = KickStarter.playerInteraction.GetActiveHotspot ();
            if (activeHotspot == null)
            {
                // Clicked on nothing
                Debug.Log ("Clicked on nothing");
                PlayAnim (-1);
            }
            else if (activeHotspot.IsSingleInteraction ())
            {
                // Clicked on single-use Hotspot
                int iconID = activeHotspot.GetFirstUseIcon ();
                Debug.Log ("Clicked " + iconID);
                PlayAnim (iconID);
            }
        }
    }


    private void PlayAnim (int ID)
    {
        _animator.SetInteger (clickIconInt, ID);
        _animator.SetTrigger (clickEffectTrigger);
    }

}

Thanks Chris. I don't full understand it yet but I will see if I can work it out.
