Viewport

Viewport allows you to add and remove objects on scene, control their positions, rotations and do other basic operations.

Creation/Selection Objects

The empty game doesn’t look fun. To make it visually appealing we need to add various game objects. Thunder Engine supports many visual components like 2D sprites and 3D meshes.

Now let’s create something! There are a few methods how to placing objects on the scene. The simplest way is to just drag and drop objects from a Content Browser.

As you probably noticed the created object is automatically selected. The selected object has an orange highlight around it. A developer has the ability to change the color and thickness of a highlighter or completely disable it. During development, you would need to select objects on the scene. Just click by LBM on an object and it will be selected.

Toolbar

The toolbar contains a various controls to move, rotate and scale selected objects.

Select	Selects objects and nothing else. Can be used to prevent not intentional changes.
Move	Select and Move. Allows moving selected objects by axes.
Rotate	Select and Rotate. Allows rotate selected objects by axes.
Scale	Select and Scale. Allows scale selected objects by axes.
Transform	Select and Transform. Allows move and scale selected 2D objects.
2D	Switches the Viewport between 2D and 3D modes.
Orientations	Switches between Global and Local axes orientations: Global - Align the transformation axes to world space. Local - Align the transformation axes to the selected objects’ space.
Show	Switches the viewport position and shows various buffers used during rendering.

Positioning Actors

After an object has been placed on the scene, we may want to move, rotate, or resize it. Using Toolbar we can do this right in the Viewport.
