- the scrollbar is .ui-scrollbar with a .ui-thumb, styled by the default sheet or a theme; a press on the thumb holds it at the point it was taken and the pointer moves it in proportion, a press on the track jumps the thumb's middle there and holds it, and neither presses what is under the bar (it used to centre the thumb on the pointer and press the row beneath as well); - while a popover is up only scroll boxes inside it take the pointer, and a press outside it that closes it forgets any press in progress; - a transition ends exactly on its value (it stopped a rounding error short, at every frame rate). Tests: ui_popover_mouse, ui_scrollbar, ui_ease (60/120/180/240 Hz). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Examples
A curated tour of Ludic, grouped by intent. Every example here is exercised by
the test suite (bin/ludic-dev test / bin/ludic-dev selfhost-test), so nothing in this
directory silently rots.
Run any program straight from the repository root (so assets/ resolves):
bin/ludic build examples/games/snake.ludic # compile + open a real window
bin/ludic build examples/games/snake.ludic --headless # render one frame to build/out.ppm
bin/ludic examples/lang/offline_rewards.ludic # compile + run a plain program
games/ — complete, windowed games
| Example | What it shows |
|---|---|
games/snake.ludic |
A full game from primitives: input, grid, growth, collision, score. |
games/menu.ludic |
A retained-UI title screen — the UI declared as data. |
games/chronorift.ludic |
A 2D co-op JRPG: overworld, dungeon, random encounters, turn battle, boss, save. The entry file imports the modules under games/chronorift/. |
rendering/ — drawing primitives
| Example | What it shows |
|---|---|
rendering/draw_prims.ludic |
The extended Screen.* primitives — line, circle, triangle, fill, sprite. |
ecs/ — the entity-component world
| Example | What it shows |
|---|---|
ecs/hello.ludic |
The smallest program that exercises the ECS pipeline. |
ecs/world_get.ludic |
Reflection: read/write a component by name. |
ecs/world_scan.ludic |
Reflection: scan the world and identify each entity. |
ecs/world_query.ludic |
Reflection: iterate the world by property. |
ecs/world_spawn.ludic |
Reflection: a mod spawns a fresh entity by model id. |
ecs/world_mixed.ludic |
Reflection: get/set through real struct offsets. |
ecs/world_dyn.ludic |
Reflection: register a brand-new component at runtime. |
events/ — the event bus
| Example | What it shows |
|---|---|
events/events.ludic |
EV0: the event-bus core — declare, emit, @On. |
events/mod_events.ludic |
Two listeners on one event, driven from a mod. |
events/cancel.ludic |
EV3: cancellable (decision) events. |
events/recurse.ludic |
EV6: re-entrant emit is depth-bounded — no runaway cycle. |
events/promote.ludic |
EV1: @Public promotes a lifecycle hook to a public event. |
events/prop_events.ludic |
EV1 for properties: attach/detach events. |
events/scene_events.ludic |
EV1 for scenes: on-enter / on-exit events. |
events/program_events.ludic |
EV1 for the program scope: start/quit events. |
events/layer_events.ludic |
EV1 for layers + a public layer's show/hide events. |
events/scoped.ludic |
A despawned entity drops out of subsequent event work. |
networking/ — deterministic multiplayer (N0–N6)
Each maps to a stage of the Networking design; all run over the compiler's built-in loopback transport with zero foreign code.
| Example | What it shows |
|---|---|
networking/net_echo.ludic |
N0: the transport seam. |
networking/net_snapshot.ludic |
N1: whole-world snapshot to a memory buffer. |
networking/net_sync.ludic |
N2: @Sync replication codegen. |
networking/net_owner.ludic |
N3: entity ownership. |
networking/net_rpc.ludic |
N4: remote events / RPCs. |
networking/net_roles.ludic |
N5: handler roles + the drivable sim. |
networking/net_demo.ludic |
N6: a networked game end to end, in pure Ludic. |
networking/net_rt.ludic |
A blessed server-authoritative replication runtime. |
lang/ — language & standard-library tour
| Example | What it shows |
|---|---|
lang/annotations.ludic |
The annotation-first style: @Queries / @Computed / @OnSpawn / @Handles. |
lang/qdecl.ludic |
@Queries desugaring to the query system. |
lang/lifecycle.ludic |
The whole game lifecycle as @-hooks, in firing order. |
lang/detach.ludic |
Structural attach/detach + @OnAttach / @OnDetach. |
lang/reason.ludic |
Reason-carrying teardown (@OnDespawn: Despawned vs Quit). |
lang/toggle.ludic |
enable/disable at the three ECS scopes. |
lang/scenes.ludic |
One active scene at a time, handlers grouped into layers. |
lang/strings.ludic |
Strings as values: compare, join, interpolate, slice. |
lang/operators.ludic |
Compound assignment on every type, unary minus, char escapes, list literals. |
lang/rng_demo.ludic |
The Random.* extensions (value/int/sign). |
lang/time_demo.ludic |
Time.frame / elapsed / delta. |
lang/offline_rewards.ludic |
A worked idle-game example over the Time/Date/Duration stdlib. |
library/ — building and linking a shared library
A how-to for compiling a .ludic module to a native .dylib/.so/.dll and
linking a second program against it via extern fn:
bin/ludicc examples/library/combat.ludic --shared -o build/libcombat.dylib
bin/ludicc examples/library/arena.ludic -o build/arena -Lbuild -lcombat
| Example | What it shows |
|---|---|
library/combat.ludic |
Exported functions callable across the C ABI. |
library/arena.ludic |
A program that links against the shared library. |
