# clickCount

> Gets the number of consecutive times a down-up sequence was executed in a short amount of time with the same pointer ID and button.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine.UIElements](/engine/6000.5/script-reference/unityengine/uielements.md)
* **Assembly:** UnityEngine.UIElementsModule

```csharp
int clickCount { get; }
```

### Remarks

There are two different formulas used to determine the value for clickCount.

If the event is a [ClickEvent](/engine/6000.5/script-reference/unityengine/uielements/clickevent.md), a special data structure tracks click counts for each pointer ID, and will use that click count when initializing the next click event:

* clickCount is incremented on [PointerDownEvent](/engine/6000.5/script-reference/unityengine/uielements/pointerdownevent.md).

* Time is measured between consecutive [PointerDownEvent](/engine/6000.5/script-reference/unityengine/uielements/pointerdownevent.md)s.

* The time limit is 0.5 seconds by default but can vary on some platforms.

* clickCount is reset whenever an event with a different pointer ID or button than the previous one is sent.

* clickCount is reset on [PointerDownEvent](/engine/6000.5/script-reference/unityengine/uielements/pointerdownevent.md) if its target is not the same as the previous [PointerDownEvent](/engine/6000.5/script-reference/unityengine/uielements/pointerdownevent.md).

If the event is not a [ClickEvent](/engine/6000.5/script-reference/unityengine/uielements/clickevent.md), the value for clickCount does not follow a strict formula, but rather it is determined by the active input framework and platform conventions. The amount of time allowed and whether that time is measured between consecutive [PointerDownEvent](/engine/6000.5/script-reference/unityengine/uielements/pointerdownevent.md)s or between a [PointerUpEvent](/engine/6000.5/script-reference/unityengine/uielements/pointerupevent.md) and the next [PointerDownEvent](/engine/6000.5/script-reference/unityengine/uielements/pointerdownevent.md) varies.

To remain consistent in your code, don't depend on clickCount for other events than [ClickEvent](/engine/6000.5/script-reference/unityengine/uielements/clickevent.md) if possible. We recommend keeping track of click counts manually by registering callbacks to [PointerDownEvent](/engine/6000.5/script-reference/unityengine/uielements/pointerdownevent.md) and [PointerUpEvent](/engine/6000.5/script-reference/unityengine/uielements/pointerupevent.md) on the [\_visualTree](/engine/6000.5/script-reference/unityengine/uielements/ipanel/visualtree.md) using the [TrickleDown.TrickleDown](/engine/6000.5/script-reference/unityengine/uielements/trickledown/trickledown.md) phase to monitor all incoming Panel events. The code below shows an example implementation.

### Examples

```csharp
using UnityEngine;
using UnityEngine.UIElements;

public class ClickCountMonitor
{
    public int ClickCount { get; private set; }

    private float doubleClickTime;
    private int lastPointerId = -1;
    private int lastButton;
    private IEventHandler lastTarget;
    private float lastTime;

    public ClickCountMonitor(IPanel panel, float doubleClickTime = 0.5f)
    {
        this.doubleClickTime = doubleClickTime;

        panel.visualTree.RegisterCallback<PointerDownEvent>(e =>
        {
            CheckResetConditions(e);
            ClickCount++;
        }, TrickleDown.TrickleDown);

        panel.visualTree.RegisterCallback<PointerUpEvent>(e =>
        {
            CheckResetConditions(e);
        }, TrickleDown.TrickleDown);
    }

    private void CheckResetConditions(IPointerEvent e)
    {
        if (e.pointerId != lastPointerId || e.button != lastButton || ((EventBase)e).target != lastTarget ||
            Time.time >= lastTime + doubleClickTime)
            ClickCount = 0;
        lastPointerId = e.pointerId;
        lastButton = e.button;
        lastTarget = ((EventBase)e).target;
        lastTime = Time.time;
    }
}
```
