Description

Summary

While editing Tilemaps, the process of changing the selected source tile from the Tile Palette takes a considerable amount of time, mostly due to mouse travel and readjustment time. Keyboard shortcuts to change selection could improve this workflow.

Analysis

  • All selection shortcuts should work both in the Tile Palette itself, and in the Tilemap Editor. A good way to achieve this might be to expose the required high level functionality in public API of the Tile Palette and invoke it from both places when the keys are detected.
  • Arrow keys could move the current selection along the view.
    • If more than one tile was selected, first collapse to the top left selected tile.
    • If no tile was selected, select the top left [0, 0] tile.
  • Shift + Arrow keys expand / shrink the selection area in the specified direction.

Contributor guide

Research direction
Identify the two source files (SourcePaletteTilesetView.cs and TilemapEditorCamViewState.cs) and implement keyboard input handling for selection navigation using arrow keys and Shift+arrow keys. Expose public API in the Tile Palette and invoke it from both views.
