# Creating a Custom Setup Action

## Creating a Custom Setup Action

{% tab title="Blueprint" %}

* Create a Blueprint class derived from **Indicator Setup Action**.

* Drag off the `Descriptor` pin and call any setter on `UIndicatorDescriptor`.

* Add the Blueprint action class to a `UIndicatorSetupConfig` asset.

## Typical Config Composition

The following action stack produces a screen-space enemy indicator with a clamp arrow:

| # | Action                  | Key Setting                                                |
| - | ----------------------- | ---------------------------------------------------------- |
| 1 | **Indicator Class**     | `WBP_EnemyIndicator`                                       |
| 2 | **Projection Mode**     | Character: `ComponentBoundingBox`, Other: `ComponentPoint` |
| 3 | **Bounding Box Anchor** | Character: `(0.5, 0.5, 1.0)`                               |
| 4 | **Set Align**           | `HAlign_Center`, `VAlign_Bottom`                           |
| 5 | **Clamp To Screen**     | `true`                                                     |
| 6 | **Arrow Brush**         | `T_Arrow`, show arrow: `true`                              |

## Action Ordering

Actions execute in array order. If one action depends on another's output, place it after:

```
Configs[0] = UIndicatorAction_IndicatorClass      ← set widget class first
Configs[1] = UIndicatorAction_ProjectionMode       ← set projection
Configs[2] = UIndicatorAction_ClampToScreen        ← enable clamping
Configs[3] = UIndicatorAction_ArrowStyle           ← arrow needs clamping already set
Configs[4] = UMyIndicatorAction                   ← custom logic last
```
