# TODO - GUI and UX
|
|
|
|
## Fix existing stuff
|
|
|
|
- if a lane could feasibly have multiple turn options but doesnt, print "ONLY"
|
|
- audit all panics
|
|
- tune text color, size, padding
|
|
|
|
- click cycle diagram to edit duration
|
|
|
|
- toggle rewind mode
|
|
- yellow or flashing red/yellow for yields
|
|
- text box entry: highlight char looks like replace mode; draw it btwn chars
|
|
|
|
- navigator
|
|
- show options on map
|
|
- stop jumping text size
|
|
|
|
## General ezgui stuff
|
|
|
|
- optionally limit canvas scrolling/zooming to some map bounds
|
|
- when dragging, dont give mouse movement to UI elements
|
|
- start context menu when left click releases and we're not dragging
|
|
- can we change labels in modal or top menu? show/hide
|
|
- distinguish hints from status of modal menus, for hiding purposes
|
|
- move context menus out of ezgui
|
|
- simplify/remove UserInput.
|
|
- maybe separate impls for context, wizard, modal menu make sense.
|
|
|
|
## New features
|
|
|
|
- swap direction of one-way
|
|
- convert between one- and two-way if there's enough space
|
|
- collapse smaller roads/neighborhoods and just show aggregate stats about them (in/out flow, moving/blocked within)
|
|
- undo support for edits
|
|
|
|
## Better rendering
|
|
|
|
- depict residential bldg occupany size somehow
|
|
- render cars with textures?
|
|
- rooftops

|
|
- color tuning
|
|
- neutral (white or offwhite) color and make noncritical info close to
|
|
that. http://davidjohnstone.net/pages/lch-lab-colour-gradient-picker,
|
|
chroma < 50
|
|
|
|
## Performance
|
|
|
|
- it's a pity we have to redo DrawCar work for all those parked cars every tick
|
|
- show FPS or some kind of measure of lag
|
|
- sleep better in the event loop
|
|
- first make UserInput borrow state and not need to consume
|
|
- more speculative performance ideas
|
|
- specialized shaders for common shapes like circles?
|
|
- try https://docs.rs/dymod/0.1.0/dymod/ to link in a release-mode ezgui crate?
|
|
|
|
## Depicting traffic unzoomed
|
|
|
|
- strange things to depict
|
|
- cars partly straddling roads
|
|
- some lanes backed up, others moving
|
|
- peds (lots of them in one position maybe!)
|
|
- intersections (simultaneous turns, some blocked, others not)
|
|
- peds waiting for bus
|
|
- general ideas
|
|
- darked colors (contrast map bg and road)
|
|
- show min/max bounds (exact max is hard, but could calculate best-case easily)
|
|
- percentage of capacity instead of an exact, moving length
|
|
- criteria
|
|
- at low zoom, easily pinpoint where things are moving and stuck
|
|
- include all agents
|
|
|
|
## Mission Edit Mode
|
|
|
|
- neighborhood
|
|
- display some instructions in the modal thing ("move a point by grabbing it")
|
|
- warp to neighborhood center and zoom out when loading one (or even hovering in the menu?)
|
|
- display all and click to edit
|
|
- draw text in map-space, or be able to scale it
|
|
- renaming
|
|
- scenario
|
|
- visualize should just be the default thing
|
|
- summarize in the modal menu, dont display the ugly text
|
|
- almost feels like a list of 3 'command' types, each of which can be visualized:
|
|
- seed cars
|
|
- spawn agents
|
|
- spawn agents from border
|
|
- kind of need to CRUD this list
|
|
- time input is very unclear, put help text in there
|
|
- combine the spawn and border spawn... choose neighborhood OR border
|
|
- choose in a menu list, or click on the map
|
|
- draw the border nodes loudly
|
|
- visualize better
|
|
- draw separate arrows src/dst, on each side of text
|
|
- draw text at a fixed size, not in screenspace, specify the font size.
|
|
- associate font size with Text, probably
|
|
- highlight a region, draw counts to/from it in some meaningful way
|
|
- timer slider (except timeslices arent neatly in hour blocks, though they maybe should be)
|
|
- a table (with color-coded entries) is actually perfect
|
