# Placement Visuals

Detailed information about how visuals are shown to the player and how to create your own.

## Intro

These features are optional and placement is possible without any visuals.

## Provided visuals

### Direction Line

Using the provided <mark style="color:blue;">**LinePlacementVisual**</mark>**&#x20;component**, you can render direction with **LineRenderer** with two points, start and finish. The component only manages the renderers state, for customisation of line visuals, configure **LineRenderer** component to change its thickness, material, shadow and more.

### Formation Positions

When <mark style="color:blue;">**UnitPlacement**</mark> has enabled `alwaysCalculatePositions`, then you can also use <mark style="color:blue;">**FormationIndicatorVisual**</mark>**&#x20;component** to show positions of unit formation while player is placing the new position and direction of the formation.&#x20;

To use this component you need to specify:

* **Unit Indicator Prefab** used for unit position indicator in a formation
* **Hide with delay** enable and specify **delay** if formation indicators should persist after placement is no longer active.

## Customisation

<mark style="color:blue;">**APlacementVisuals**</mark> is a component for utilising visuals when placing a formation in world environment with <mark style="color:blue;">**FormationPlacement**</mark>. This can be extended to support any type of visuals.&#x20;

Look for <mark style="color:blue;">**APlacementVisuals**</mark> in project to get full information about how this one communicates with the placement component. Once you implement your own, add it to the list of visual renderers on <mark style="color:blue;">**FormationPlacement**</mark> component and you're good to go!
