Runtime.setMacroX(value)

Sets the reference width in pixels of the screen the macro was made on (the width part of Runtime.setMacroSize).

Detailed Explanation

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

How To Call It

Runtime is a global table: call its functions with a dot (Runtime.<method>(...)), not a colon.

When To Use It

In system flow, design steps as observe first and act second when the API can affect device state.

Parameters and Return

Required: value. Returns nothing.

Best Combined With

Using this API with logging, error handling, and next-step control produces much more professional results than calling it in isolation.

Example Usage

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

lua
Try in Editor →
Runtime.setMacroX(1080)

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 →
Runtime.setMacroX(1080)

Simple

Wraps the base call with minimal flow control.

Simple
lua
Try in Editor →
local stepOk = true
Runtime.setMacroX(1080)
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, err = pcall(function()
  Runtime.setMacroX(1080)
end)

if not ok then
  print("API step failed: Runtime.setMacroX: " .. tostring(err))
  requestStop()
end

Detailed

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

Detailed
lua
Try in Editor →
-- In system flow, design steps as observe first and act second when the API can affect device state.
local function run_setmacrox_step()
  Runtime.setMacroX(1080)
end

local ok, err = pcall(run_setmacrox_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 →
Runtime.setMacroX(1080)
wait(200)
print("Combined with logging and flow control")
