New Widget here

What it is:
- Holding down a key (user defined) will create a circular selector for specific unit types (again user defined!) with visual feedback. These are: Riots, Assaults, Arty, Raiders, and Skirms by default.
- Upon the release of the key, your selection will be changed to the circled units.
- Setting debug to true can help you with finding keys you want.

Very primitive. Would like to hear some feedback.

I'll be releasing a new version soon which is just a circular selector. Thought I'd at least release it since it was originally made for FRrankHelwor. Was teaching some lua to FRrankHelwor as well so don't mind the comments ^^

May develop this further.

This sounds pretty good, anything better than current autogroup would be great.
Maybe you could provide some screenshoots or a vid?

The selection preview is a little primitive but here's some screen shots.



Probably needs a deeper blue but w/e


Don't you just hate it when you just want a role of units in a clusterfuck like this?




Btw: You can change the radius of the selector too! It even gives a helpful preview (it only renders for 3 frames too!)



With some time I'll make it better. I don't know how to 'highlight' units yet in openGL (my knowledge is very limited :( ). But hey, it's my first widget incorporating visuals :D

I'm wondering if there was a way to provide selection tools somehow. Finding a good key for it is hard. Circular selection might be a cool thing if I can figure out how to bind it to the mouse or something.

Nice, a bit like the 'old' selection-hotkeys of engine but with visuals.
Maybe have outline on the text, especially the blue text is hard to read I think.

For keycode constants you can include this file
https://github.com/spring/spring/blob/5f08624585852b8c8dfd1a16d020ae530269dc09/cont/LuaUI/Headers/keysym.h.lua
via
include("keysym.h.lua")
and then be like
function widget:KeyPress(key)
if (key == KEYSYMS.S) then

For TraceScreenRay and its random numbers see
https://springrts.com/wiki/Lua_UnsyncedRead#Screen_Trace
This is a bit 'guessing' and can be UB:
quote:

if Spring.ValidUnitID(pos) then
x,_,y = Spring.GetUnitPosition(pos)
elseif Spring.ValidFeatureID(pos) then
Say the ray hits the feature with ID=25. But elsewhere there is also a unit with ID=25.
Then ValidUnitID(pos) will be true but will not be what you want.
(Super unlikely but since the returned values tell if it hit a unit/feature/ground, use that.)

Instead of GameFrame() maybe try Update() because GameFrame stops ticking during pause.
(So the widget keeps working during pausewars like other GUI)

Ah yes, update would be better. The reason why I put the actual work in gameframe is because during testing I originally had it in KeyPressed, but this killed my performance (went from ~135fps to 5!).

Oh wow! That's really useful to know. I saw the other day about in-game settings, I wonder if I could read settings from there and use this to translate.

Huh. I think since it's now onlyCoords = true it shouldn't have that issue? Probably safe to remove the extra code, but I keep it there just in case. It does seem to prevent annoying snapping.

I'd have to add 'o' or 'O' to 'v' right?

I'll make changes today to reflect on this. Thanks for the helpful pointers.

Knorke-s suggestions are on the spot.
