Scene Editor

Evergine supports a complete Scene Editor. It allows creating entities, modifying them, adding / removing components. It contains the following sections:

• Scene Toolbar.
• Scene Viewport.
• Entities Hierarchy.
• Entity Details.

Scene Toolbar

It contains useful controls for adjusting the scene edition.

Control	Description
	Camera selection. Allow the Scene Viewport to visualize one of the scene cameras. Perspective is the default value, representing Evergine Studio camera.
	Set the transform manipulation in Translation Mode.
	Set the transform manipulation in Rotation Mode.
	Set the transform manipulation in Scale Mode.
/	Toggles the transform manipulation from local axis to global axis.
	When enabled, translation manipulation is done by steps of a custom value (0.5, 1, 5, 10, 50, 100)
	When enabled, rotation manipulation is done by steps of a custom value (5, 10, 15, 30, 45, 60 and 90 degrees)
	When enabled, scale manipulation is done by steps of a custom value (0.001, 0.01, 0.1, 0.5, 1, 5, 10)
	Open a dialog with the properties of the editor scene camera. (More details below)
	Toggles the visibility of the grid in the viewport.

Editor Camera properties

This dialog sets the properties of the Editor camera. This camera is the default camera when editing your scene. The properties shown in this panel are the same that appear when editing a Camera3D component. More information in this article

Scene Viewport

This area allows navigating the camera through the scene and also selecting, transforming and manipulate all the en entities of the scene (Cameras, Lights and other types).

On top of the viewport there is the Scene toolbar where the user can adjust how the viewport behaves.

Controls

Action	Description
Left Mouse	Select entity.
Right Mouse	Rotate camera.
Right Mouse + Arrows / WASD	Move camera.
Right Mouse + Mouse Wheel	Change camera speed up / down.
Right Mouse + Shift	Speed up camera by 2.
Middle Mouse	Pan camera
Mouse Wheel	Zoom in/out camera.
Ctrl + D	Duplicate selected entity.
G	Toggle Grid visibility
W	Set Translating manipulation mode.
E	Set Rotating manipulation mode.
R	Set Scaling manipulation mode.

Basic Manipulation

When selecting an entity, a Bounding Selection Box will appear and also a manipulator for adjusting the entity Transform3D.

There are 3 different transform manipulation, selected by the above keys (W, E and R), or throug the Toolbar:

Translation

Moves the entity through the scene. It allows to translate the entity:

• 3 main axis (X, Y an Z) as an one dimension translatio.
• 3 main surfaces (XY, XZ and YZ) as a two dimensional translation.

Rotation

Rotates the entity through one rotation axis. Those axis are:

• X axis.
• Y axis.
• Z axis.
• Screen Axis, the entity will rotate around the camera (using the camera forward as axis).

Scale

Scales the entity in one or more axis:

• X axis.
• Y axis.
• Z axis.
• Uniform, scales proportionally so the entity proportions remain the same.

Note

Scaling manipulations always use local axis.

Entities Hierarchy

This panel shows the entity tree of the scene. Every node represents an entity so it reflects entity hierarchy. When a node has some children mean that entity has some entity children.

Operations

• Entities can be rearranged. This will cause the entities to be relocated to another parent. When this operation is made the overal world transform (scale, rotation and translation) tries to remain constant during the process.

• Entities can be removed. Pressing the Supr button will delete the selected entity and all their children.

• Double click in an entity will focus it in the Scene Viewport.

• Clicking in the button will show the Add Entity dialog. More details in the Using Entities article.

• In the botton bar shows the total number of entities in the scene (137 in above image)

Entity Details

This panel shows all the properties of a selected entity. It shows all the entity parameters like name, tag and enable status, and also shows an accordion panel of their components. Here are some specific controls:

Controls

Control	Description
	Toggles the entity as static entity.
	Collapses the visibilisation of all the components
	Expand the visibilisation of all the components
