# Adding Abilities to Your Actors
Beyond our pre-built actors, ShikorDriftXR provides a library of powerful **Actor Components**. Think of these as reusable "ability packs" that you can add to **any actor** in your level to give it new functionalities.
This modular approach gives you incredible flexibility to create unique, interactive objects.
**How to Add a Component:**
1. Select any actor in your level.
2. In the **Details** panel, click **"+ Add"** and search for the component by name (e.g., BPC\_Highlight).
3. Select it from the list to add it to your actor.

{% tab title="BPC\_Highlight" %}
The BPC\_Highlight component is a versatile tool for providing clear visual feedback when an object is targeted or focused on by the player. It is driven by the Event Tick, ensuring a smooth and responsive effect. When you add this component to an actor, it will automatically highlight when the player looks at it.
**1. Highlight (Default)**
This is a soft, glow-like effect that appears around the edges of the object.
* **Highlight Color:** Sets the color of the fresnel glow.
* **Highlight Radius:** Controls the thickness or spread of the glow. (Technically, this adjusts the Exponent value of a Fresnel node in the material).
* **Highlight Opacity:** Controls the transparency of the glow effect.
***
**2. Outline Setup**
This style creates a hard, cartoon-like outline around the object.
* **Use Outline:** Check this box (true) to enable this mode. This will automatically disable the Fresnel and Animation modes.
* **Outline Expand:** Controls the thickness of the outline by adjusting the World Position Offset.
***
**3. Highlight Animation**
This style creates a dynamic, animated effect that can be used for a more stylized highlight.
* **Use Animation:** Check this box (true) to enable this mode.
* **Animation Speed:** Controls how fast the animation plays.
* **Animation Width:** Defines the size or spread of the animated effect.
* **Animation Opacity:** Controls the transparency of the animation.
***
**Technical Note for Advanced Users:**
The dynamic material effects of this component are powered by the **M\_Transparent** Master Material.

{% tab title="BPC\_XrayMode" %}
The BPC\_XrayMode component is a powerful visualization tool designed to reveal hidden details within your models, such as BIM connections, electrical wiring, or plumbing inside walls.
When this component is added to a static mesh, it allows that mesh to be turned semi-transparent via a global toggle in the runtime UI, creating an "X-Ray" effect that reveals whatever is inside or behind it.
**How it Works:**
1. Add the BPC\_XrayMode component to any static mesh actor in your level that you want to make "X-Ray-able" (e.g., a wall, a floor, a machine casing).
2. When the game is running, a new **"X-Ray Mode" button** will automatically become visible in the main UI.
3. Clicking this button will toggle the X-Ray effect ON and OFF for **all actors** in the level that have this component. When ON, the meshes will switch to the specified transparent material, making any objects behind them visible.
**Configuration (Details Panel):**
The setup for this component is incredibly simple
* **Xray Material:**
* **What it does:** This is the most important setting. It defines the transparent material that will be applied to the mesh when X-Ray mode is activated.
* **How to use:** We provide a default MI\_Xray material instance that you can use out-of-the-box. However, for full control, you can create and assign your own custom transparent or semi-translucent material here to achieve the exact visual style you want.

{% tab title="BPC\_ShowDotWidget" %}
The BPC\_ShowDotWidget component is a simple but essential tool for improving user experience. Its primary job is to display a widget on the screen when the player focuses on an interactable object, signaling that an action can be performed (e.g., "Press F to open").
**How it Works:**
When you add this component to any actor that requires player interaction (like our BP\_InteractDirectional or BP\_ManualDirectional actors), this widget will automatically appear in the viewport when the player looks at the actor, and disappear when they look away.
**Configuration (Details Panel):**
This component is designed for simplicity, with one powerful customization option.
BPC_ShowDotWidget
* **Chose Widget:**
* **What it does:** This is the only setting for this component. It allows you to select which User Widget should be displayed on the screen when the actor is focused on.
* **How to use:**
* **Default:** By default, it is set to our pre-built WBP\_Interact widget, which shows a simple "Press F" prompt.
* **Customization:** For full creative control, you can create your own unique UI widget (e.g., with a different icon, text, or animation) and assign it here to perfectly match the visual style of your project.
