# LoopCheckDecorator

LoopCheckDecorator can be written in a C# script.

## How to create

1. Click the “+” button in the Project window.
2. Select Logic Toolkit > Scripts > Decorator > Loop Check Decorator C# Script from the menu.
3. Enter the script name and confirm with Enter.

## How to write a script

- Create a class that inherits from `LogicToolkit.BehaviorTree.LoopCheckDecorator`.
- Apply `System.SerializableAttribute` to the type.
- Implement `protected override bool OnNext()` and write the processing at runtime.
- `protected override void OnActivated()` is called when activated.
- `protected override void OnDeactivated()` is called when it becomes inactive.

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    using LogicToolkit;
    using LogicToolkit.BehaviorTrees;

    [System.Serializable]
    public class LoopCheckDecoratorExample : LoopCheckDecorator
    {
        private int count;

        // OnActivated is called when activated.
        protected override void OnActivated()
        {
            count = 0;
        }

        // Called when the node finishes executing
        protected override bool OnNext(bool result)
        {
            count++;

            // Returns true if the node is executed repeatedly
            return result && count < 10;
        }

        // OnDeactivated is called when it is deactivated.
        protected override void OnDeactivated()
        {
        }
    }

In this example, we will repeat the execution of the node up to 10 times as long as the result is successful.

In addition, a script called LoopCount is included in advance as a similar function.
