Cube-Factory

This unity asset instantiates, keeps track of and removes cubes based on player input.

Installation

This repository is a drop-in script, not a Unity project. There is no scene, no Assets/ folder and no package manifest here — only the single MonoBehaviour in src/.

1. Copy src/CubeFactory.cs into the Assets/ folder of an existing Unity project.
2. Let Unity finish compiling; the CubeFactory component becomes available.

Setup

1. Create a cube prefab (for example, from a built-in Cube GameObject).
2. Add an empty GameObject to the scene.
3. Attach the CubeFactory component to it.
4. Assign the cube prefab to the component's Cube Prefab field in the Inspector.

The Cube Prefab field has no default value. If it is left unassigned, pressing E spawns nothing and writes an error to the Console naming the field to assign.

Controls

Key	Action
E	Spawns a cube and adds it to the tracked list
R	Destroys one tracked cube, if any remain

Both keys are handled in Update() and are read once per key press, not per frame held.

Behaviour

• Every cube is spawned at the world origin, (0, 0, 0). Spawning several cubes therefore produces a stack of overlapping cubes at the same point rather than a visible spread.
• R removes the oldest cube still tracked, not the most recently spawned one.
• Pressing R with no cubes tracked does nothing.
• After each spawn and each removal, a labelled message naming the action and the resulting cube count is written to the Console — for example CubeFactory: spawned cube, count is now 1.
• Pressing E while Cube Prefab is unassigned logs an error naming the field and leaves the tracked list unchanged.

Inspector fields

Field	Type	Purpose
cubePrefab	GameObject	The prefab instantiated on each spawn. Must be assigned.
cubes	List<GameObject>	The cubes currently tracked. Populated at runtime; assigning it in the Inspector is not expected.
