Build Mode

Build Mode is the editor for Mirror Engine, similar to when you open another game engine like Unreal, Unity, or Godot/Redot.

Play Mode is what the player plays, similar to when you open a game on Steam. When you publish your game, it'll run in Play Mode with the first scene you've selected.

Real-Time Collaboration

Everything you build is in real-time with mirrored multiplayer. Similar to Minecraft, when an item is in-world for you, it's instantly available for everyone else.

Scenes

Games in Mirror Engine are live, including Build Mode.

Two players can build the same scene at the same time, or they can be in different scenes in the same game.

If you're in the same scene as another player, you can see their changes in real-time.

Gizmos

In Build Mode, click any entity and you'll see a gizmo attach it. These can be used to change the position, rotation, and scale of the entity.

Transform Menu

Click the bottom-right "Transform" button to open the transform menu. When you change the entity's position, rotation, or scale via a gizmo, you'll see these values update in real-time.
