# Through Code

Setting up your GOAP system using code is the most flexible way to configure your GOAP system. This method is more difficult to use than the `ScriptableObjects` method, but allows for a much more dynamic setup.

{% hint style="info" %}
**Info** By using code to setup your GOAP system, you can use generic classes. This can make the setup of your GOAP system more flexible.
{% endhint %}

{% hint style="info" %}
**Example** The complex demo uses code as the configuration method.

## Sets

To create a set, you must create a class that inherits from `GoapSetFactoryBase`. This class must implement the `Create` method which returns a `IGoapSetConfig`. To make building the set easier, you can use the `GoapSetBuilder` class.

{% code title="GoapSetConfigFactory.cs" lineNumbers="true" %}

```csharp
using CrashKonijn.Goap.Behaviours;
using CrashKonijn.Goap.Classes.Builders;
using CrashKonijn.Goap.Configs.Interfaces;
using Demos.Complex.Classes;
using Demos.Complex.Classes.Items;
using Demos.Complex.Factories.Extensions;
using Demos.Complex.Interfaces;
using Demos.Shared;

public class GoapSetConfigFactory : GoapSetFactoryBase
{
    public override IGoapSetConfig Create()
    {
        var builder = new GoapSetBuilder("ComplexSet");
        
        // Goals
        builder.AddGoal<WanderGoal>()
            .AddCondition<IsWandering>(Comparison.GreaterThanOrEqual, 1);

        builder.AddGoal<FixHungerGoal>()
            .AddCondition<IsHungry>(Comparison.SmallerThanOrEqual, 0);

        // Actions
        builder.AddAction<WanderAction>()
            .SetTarget<WanderTarget>()
            .AddEffect<IsWandering>(true)
            .SetBaseCost(1f)
            .SetInRange(0.3f);

        builder.AddAction<PickupItemAction<IEatable>>()
            .SetTarget<ClosestTarget<IEatable>>()
            .AddEffect<IsHolding<IEatable>>(true)
            .AddCondition<IsInWorld<IEatable>>(Comparison.GreaterThanOrEqual, 1)
            .SetBaseCost(1f)
            .SetInRange(0.3f);

        // Target Sensors
        builder.AddTargetSensor<WanderTargetSensor>()
            .SetTarget<WanderTarget>();

        builder.AddTargetSensor<ClosestItemSensor<IEatable>>()
            .SetTarget<ClosestTarget<IEatable>>();

        // World Sensors
        builder.AddWorldSensor<IsHoldingSensor<IEatable>>()
            .SetKey<IsHolding<IEatable>>());

        builder.AddWorldSensor<IsInWorldSensor<IEatable>>()
            .SetKey<IsInWorld<IEatable>>();

        return builder.Build();
    }
}
```

{% endcode %}

### Adding the set to GOAP

Add the created class to a GameObject in the scene. Add it to the list on the `GoapRunnerBehaviour` component. This will initialize the set.

### Adding the set to the agent.

Using a script, set the `GoapSet` property on an agent.

{% code lineNumbers="true" %}

```csharp
var goapRunner = FindObjectOfType<GoapRunnerBehaviour>();
var set = goapRunner.GetSet("ComplexSet");

agent.GetComponent<AgentBehaviour>.GoapSet = set;
```

{% endcode %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://goap.crashkonijn.com/goap-v2/config/code.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
