Scene / Level
A saved playable space.
Unity uses Scene, Unreal uses Level, Godot uses Scene in a more flexible way, and Roblox often treats the published place or workspace setup as the environment container.
Terminos entre engines
Compara el mismo concepto entre distintos engines en lugar de estudiarlos por separado.
Object in the world
The thing you place and control.
Unity calls it a GameObject, Unreal usually uses Actor, Godot uses Node-based scenes, and Roblox often uses Parts, Models, or Instances.
Reusable template
A way to duplicate configured content.
Unity has Prefabs, Unreal often uses Blueprint classes or placed actors, Godot uses instanced scenes, and Roblox commonly reuses Models or stored assets.
Visual scripting
Logic without typing everything by hand.
Unreal is strongest here with Blueprint. Unity has had visual scripting options, Godot includes visual tools in narrower areas, and Roblox remains more script-centered.
UI root
Where interface elements start.
Unity uses Canvas, Unreal uses Widget Blueprint and viewport creation, Godot uses Control nodes, and Roblox uses ScreenGui under StarterGui or PlayerGui.
Startup event
What runs at the beginning.
Unity often uses Start, Unreal commonly uses BeginPlay, Godot uses _ready, and Roblox often begins from a Script or LocalScript when the object becomes active.
