Handle-Registry (get_pos + set_pos + speed callbacks) + lib-driven auto-wire (bind_move_action + bind_target_provider) + per-frame movement with arrive-snap. Move-only execution; context-dispatch deferred to P.4. See: meta/docs/superpowers/specs/2026-05-14-p3-7-lib-command-design.md
lib-core.command — v0.1.0
Move-Commands für registrierte Units. RTS-Style Click-to-Move (RMB → bewegt selected Units).
Quick Setup
local command = require("lib-core.command")
local input = require("lib-core.input")
local selection = require("lib-core.selection") -- target-provider source
input.bind("rmb", { "mouse_right" })
command.bind_move_action("rmb")
command.bind_target_provider(function() return selection.list() end)
-- Register each movable unit (read+write callbacks + speed):
local handle = command.register(
function() return { x = unit.x, y = unit.y } end,
function(nx, ny) unit.x = nx; unit.y = ny end,
100 -- px/s
)
-- per-frame:
function update(ctx, dt)
command.update(dt)
end
API
- Registry:
register(get_pos_fn, set_pos_fn, speed) → handle,unregister(h),count_registered() - Speed:
set_speed(h, n)/speed(h) → n - Issue (programmatic):
move_to(handles, x, y),cancel(h),cancel_all() - State-Query:
current(h) → {type, target_x, target_y}|nil,is_moving(h) → bool - Bindings:
bind_move_action(name),bind_target_provider(fn) - Settings:
set_arrive_threshold(n)/arrive_threshold(),set_enabled(b)/enabled() - Per-Frame:
update(dt)
