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)
