Map:clear()

Clears temporary state or data under Map.

Detailed Explanation

This section explains when to use the API, how to call it, and which structures it works best with in production flow.

What It Does

Map:clear performs one focused job in script flow and can be chained cleanly with other API steps. Clears temporary state or data under Map.

When To Use It

In data flow, chaining JSON, Regex, Str, Map, and File steps to normalize intermediate values reduces error risk. This API becomes most valuable in multi-step chained scenarios.

Parameters and Return

This entry does not require mandatory parameters. This API is primarily side-effect driven; the important result is the device state change rather than the raw return value.

Best Combined With

When combined with Str, JSON, Regex, Array, Map, and File, data transformation becomes much more readable in script flow.

Example Usage

The snippet below is a starter pattern that can be applied directly in runtime flow.

lua
Try in Editor →
-- Map:clear
local result = Map:clear()
-- Use the result in your script flow

Copyable Progressive Examples

From foundation to combined usage, each level is provided as a separate code block so you can copy the level you need and adapt it directly.

Foundation

Shows the shortest direct way to call the API.

Foundation
lua
Try in Editor →
-- Map:clear
local result = Map:clear()
-- Use the result in your script flow

Simple

Wraps the base call with minimal flow control.

Simple
lua
Try in Editor →
local stepOk = true
-- Map:clear
local result = Map:clear()
-- Use the result in your script flow
if stepOk then
  wait(200)
end

Practical Flow

A practical pattern for real macros with pcall, logging, and guards.

Practical Flow
lua
Try in Editor →
local ok, result = pcall(function()
  -- Map:clear
  local result = Map:clear()
  -- Use the result in your script flow
end)

if not ok then
  print("API step failed: Map:clear")
  requestStop()
end

Detailed

This level packages the API into a reusable helper with error reporting.

Detailed
lua
Try in Editor →
-- In data flow, chaining JSON, Regex, Str, Map, and File steps to normalize intermediate values reduces error risk.
local function run_clear_step()
  -- Map:clear
  local result = Map:clear()
  -- Use the result in your script flow
end

local ok, err = pcall(run_clear_step)
if not ok then
  toast("Step failed")
  print(err)
end

Combined

Combines the API with related structures to form a more realistic workflow.

Combined
lua
Try in Editor →
-- Map:clear
local result = Map:clear()
-- Use the result in your script flow
local raw = File.read("macro.log")
local normalized = Str.trim(raw)
print(normalized)
