Scene Edit

Scene Edit icon_tasker.png

The scene editor is used for designing custom scenes.

The editor consists of three areas:

Display Area

The main part of the editor, where the position and size of elements are arranged. The display area has two modes dependent on the setting of the magnifying glass icon in the corner.

Preview Mode

This mode shows the scene as it will appear when displayed.

  • CLick-and-drag on the edge of the scene to resize it

Editing Mode

This mode is zoomed to make editing easier.

  • Long-click on an empty area to create a new element positioned there
  • Long-click on an element to get options for the element
  • Click on an element to edit it.
  • Click-and-drag on the centre of an element to move it
  • Click-and-drag on the edge of an element to resize it

When moving and resizing, the sides of elements are snapped to a grid to make alignment easier. The grid size is unique to each scene and can be changed via Menu / Grid Size.

Tool Bar


Allows undo of all operations, up to 20 steps in the past.

New Element

Create a new element in the middle of the scene. Useful if the scene is already cluttered with a lot of elements so there is no free space.

Touch Mode

There are three touch modes which decide the effect of taps on the display area. Normal Mode is described above. Move Mode is intended to make it easier to reposition elements. Resize mode is for making resizing easier.

Menu Options

Background Colour

A complex background can be set by long-tapping an element and specifying it as the background element. If a uniform colour is sufficient, it can also be specified with this menu option.

However, there is a special case where it's a good idea to specify a background colour even if you already have a background element. A scene is resized to fit the container into which it's placed, but in some cases (e.g. when it is shown as a full screen activity) there will be margins left on one side of the container because the aspect ration of the scene (the relative size of its width and height) of a scene is never changed. In such a case, the margins are coloured with the background colour specified here.

Element Long-Click Options

Set Background

An element which is set as the scene background is resized to always fill the whole scene and interferes less with selection of other elements. To reverse this, long-tap on it and select Set Foreground.


When an element is positioned satisfactorily, it can be pinned to make it easier to select and manipulate other elements. To reverse this, long-tap on it and select Unpin.

Set Depth

Each element has a particular depth which is unique to it. Deeper elements are obscured by shallower elements which overlap them.
