aeldardin-rooms's Issues

Improve handling of canvas edge

Currently, dragging the of the edge of the map when creating a room aborts the process -- i.e. the room doesn't get created.

There's nothing warning you that that will happen, or even where the edge is.

In the short term, this can be fixed by drawing a background texture (e.g. a grid) so the edges are obvious, by drawing an actual border, or by making the canvas extend to the edges of the window (at least horizontally).

In the long term, I need to support creating maps bigger than the screen -- which means zooming and scrolling functionality.

Dragging the new-room box into an existing room cancels the room and can cause renumbering

I haven't fully reproduced this yet -- it's caused by some sequence of dragging into existing rooms, releasing the mouse (selecting the existing room), deleting the new room, and then adding and deleting more rooms.

Allow clicking and dragging to add rooms

Proposed behaviour:

• Click on an (empty?) part of the map
• As you drag, the proposed room appears -- snapping to grid lines
• Release the mouse, and the room is added to the map.

Support adding doors

To have a minimally useful map editor, I need to support adding doors between rooms (via both the HTML and canvas UIs, as per usual).

New rooms sometimes end up selected

This seems to depend on which direction you moved the mouse to create the room, but not reliably so.

They should either be consistently selected, or consistently not -- currently I'd prefer not selected, but that may change if I change how selection works.

Implement partial updates for HTML view

Currently, the HTML view gets completely rebuild every time anything changes.
This probably slows things down, and I suspect it would cause bogus notifications from screen readers.

More importantly, it resets the value and focus state of form fields. Since this happens after every change to the add-room fields, it makes the text-based add-room form almost unusable.

Changes like this should just update the specific field affected.

• Implement partial updates for the add-room form field.
• Implement partial updates for the whole HTML UI (requires adding new events to the model).

Support saving maps you create

At the moment, the map you edit exists only in the editor itself, and is gone completely as soon as you close the tab.
We should have some kind of save/load feature, either to local storage, or the filesystem (or a server, but that's a whole other kettle of fish).
