The Master Tool

Open the Master Tool

1. Open the game in the editor.
2. Use the tool dropdown in the upper-left editor toolbar.
3. Select Master.
4. Use the scene dropdown beside the controller dropdown to choose the scene you want to edit.
5. Use the disk button in the upper-right editor toolbar to save the current game graph after making changes.

What Is Already in a New Scene

When you create a scene with the Master tool, Gameatude creates a usable starter scene. You do not need to add a floor just to begin.

• A Plane primitive is already present at the origin. It is the starter floor.
• The Plane is 1000 by 1000 units and is rotated flat.
• Ambient and directional lights are already present.
• A space sky is already present.
• A perspective camera is already present.

You can select and edit or delete these starter items just like any other scene item.

Create and Name a Scene

1. Open the Game Graphs section on the right side of the Master tool.
2. Click Add New Scene.
3. Enter the scene name when prompted.
4. Wait for the editor to switch to the newly created scene.
5. To rename the current scene later, enter a new value in Scene Name and click Apply Name.
6. Save the game graph with the disk button.

Use the Scene View

1. Choose an editor controller from the controller dropdown at the top of the editor. Orbit is the normal general-purpose editor view.
2. Use the camera-view dropdown to view the scene from Perspective or from one of the six axis directions.
3. Open the menu button in the upper-right editor toolbar when you need visual helpers.
4. Enable Grid to show the grid.
5. Enable Axis to show the world axes.
6. Enable Collision to show invisible collision geometry.
7. Enable Normals or Octree only when diagnosing those systems.

Select an Object

1. Click the hand button in the Edit toolbar to turn scene selection on.
2. Click an editable object in the scene.
3. Confirm the selection in the Game Graph tree and in the Edit Selected panel.
4. Click the hand button again when you are finished selecting so you do not accidentally select objects while navigating the scene.

Keep an Object Out of Click Selection

1. Select the object normally.
2. Click the hand-and-lock button to make the selected object unclickable in the current browser for the current scene.
3. Use the hand-and-list button to review or remove unclickable items.
4. Use Clear All in that dialog when you want to restore normal selection for every listed item.

Unclickable items are a browser convenience for the current scene, not a saved game-graph setting.

Add a Primitive

1. Open Add Primitives in the left panel.
2. Choose a primitive icon. The available primitive types are Box, Capsule, Circle, Cone, Cylinder, Decal, Dodecahedron, Icosahedron, Lathe, Octahedron, Plane, Ring, Sphere, Tetrahedron, Text, Torus, and Torus Knot.
3. Set the displayed geometry parameters before placing the primitive. The fields change to match the selected primitive.

5. Choose a color or choose a material in the material picker.
6. Choose Front, Back, or Both for the primitive material side when needed.
7. Set placement snap if you need the object to align to an increment.
8. Choose world rotation or camera-facing rotation for placement.
9. Choosing a primitive turns on the Add Primitives placement mode. Move over the scene to preview its placement, then click a surface to create it.
10. Turn off the add-primitive button in the Edit toolbar when you are finished placing primitives.
11. Save the game graph.
