* Mac app: exclude the redundant copy of rtp/ folder in the .dmg disk
image as it only needs to live inside the .app bundle.
* Fix the settings.json file to be initialized and saved to disk on
first launch of the game, and the crosshair color default.
* Fix the chdir detection in main.go especially to locate the rtp/
folder inside the macOS app bundle.
New category for the Doodad Dropper: "Technical"
Technical doodads have a dashed outline and label for now, and they
turn invisible on level start, and are for hidden technical effects on
your level.
The doodads include:
* Goal Region: acts like an invisible Exit Flag (128x128), the level is
won when the player character touches this region.
* Fire Region: acts like a death barrier (128x128), kills the player
when a generic "You have died!" message.
* Power Source: on level start, acts like a switch and emits a
power(true) signal to all linked doodads. Link it to your Electric
Door for it to be open by default in your level!
* Stall Player (250ms): The player is paused for a moment the first time
it touches this region. Useful to work around timing issues, e.g.
help prevent the player from winning a race against another character.
There are some UI improvements to the Doodad Dropper window:
* If the first page of doodads is short, extra spacers are added so the
alignment and size shows correctly.
* Added a 'background pattern' to the window: any unoccupied icon space
has an inset rectangle slot.
* "Last pages" which are short still render weirdly without reserving
the correct height in the TabFrame.
Doodad scripting engine updates:
* Self.Hide() and Self.Show() available.
* Subscribe to "broadcast:ready" to know when the level is ready, so you
can safely Publish messages without deadlocks!
* Added a --window flag to the game executable to specify the startup
window resolution. Either specify an exact size (e.g. 1024x768) or a
special keyword "desktop", "mobile" or "landscape"
* Default size is "desktop" or 1024x768
* Mobile simulates a smartphone form factor of 375x812
* Landscape is mobile but flipped horizontally.
* Doodle UX isn't great on mobile but this is a step towards working on
mobile friendly UI
