## Description

Fence Builder

Fence Builder is a s&box editor library for placing fence pieces from reusable Fence Definition assets.

Setup

1. Install the library in your project.
2. In the Asset Browser, create a \`Fence Definition\` asset.
3. Add one or more entries. Each entry can use a \`Model\` or a \`Prefab\`; prefabs take priority.
4. Set \`RotationOffset\` so the segment's forward direction matches how it should run along the fence.

Use

1. Open a scene and activate the \`Fence\` tool, or press \`Ctrl+Shift+B\`.
2. Assign your \`Fence Definition\` in the tool sidebar.
3. Use \`Mode = Line\` for a straight run: click once to set the start, click again to place.
4. Use \`Mode = Spline\` for a curved run: hold left mouse, draw on a surface, then release to place.
5. Press \`Escape\` to cancel the current run.

- If you've placed an object/a lot of objects that the navmesh ignores/nav mesh agents walk through, I have added an ability to apply a nav-mesh blocker to them, it creates a new component inside the fence game object called nav mesh - area, the size of the fence/game object's collider that blocks the navmesh's creation around it. That is also present as a setting inside the fencedef files

Fence Builder measures each segment's bounds and advances placement by the measured length, so authored pieces line up without needing a fixed segment size.
