Arena, camera and lighting
Project settings, a visible arena, physical floor and camera for the 3D prototype.
Ready project or manual assembly
The archive includes all settings. For manual assembly, create SquashPrototype with the Compatibility renderer, Levels, Prefabs, Scripts folders and an editor-generated C# solution. Use Reckfell.NET.Sdk/1.0.0 and net10.0.
In Project Settings → Display → Window, set the viewport to 960 × 640 and disable Resizable. Use File → Create Scene… with an Entity3D root and save Levels/Arena.rscene:
Arena (Entity3D, SquashGame.cs)
├── Floor (StaticBody3D)
│ ├── CollisionShape3D
│ └── MeshInstance3D
├── Player (instance: Prefabs/Player.rprefab)
├── Mobs (Entity3D)
├── SpawnTimer (Timer)
├── Camera3D
├── DirectionalLight3D
├── WorldEnvironment
└── Hud (instance: Prefabs/Hud.rprefab)For manual assembly, assign asset://Levels/Arena.rscene under Project Settings → Application → Run → Main Scene. A new project may already use the automatically created Main.rprefab; F5 need not ask for another path. The main Play button and F6 run the current document. For the main level use F5 or the menu beside Play → Run Project (Main Scene).
Floor and visible geometry
| Object | Value |
|---|---|
Floor.Position | (0, -0.1, 0) |
Floor/CollisionShape3D.Shape | BoxShape3D, Size (14, 0.2, 14) |
Floor/MeshInstance3D.Mesh | BoxMesh, Size (14, 0.2, 14) |
Floor.Collision Layer | Layer 1 only; numeric value 1 |
Floor.Collision Mask | All off; numeric value 0 |
The floor top is Y = 0. The mesh renders it; the shape supports physics bodies. Keep child local positions at (0, 0, 0) and scales at (1, 1, 1). Change resource dimensions rather than scaling the physics body. Use a gray StandardMaterial3D with Roughness 0.9 on the mesh.
Camera and light
Camera3D: Position (0, 11, 12), inspector Rotation (-42.5, 0, 0) in degrees, Orthogonal Projection, Size 18, Current on. This camera looks down at the arena and does not follow the player.
DirectionalLight3D: Rotation (-50, -30, 0), Energy 1.2. Create an Environment on WorldEnvironment: Custom Color Background Mode with a dark color; Color Ambient Light Source with white color and Energy 0.4. This lights side surfaces without a sky texture.
Enter camera rotation in inspector degrees; Size = 18 applies to Orthogonal projection. Leaving Perspective selected will not give the specified framing through that Size.
Add player and UI prefabs using the next sections. For a blank game, check the launched document, Camera3D.Current and assigned meshes first. Editor preview cameras and lighting do not replace level objects.
