Capture.isRunning()

Returns true while the screen-frame cache is on: Snap.screen(), Snap.screenRefresh() and Snap.region() turn it on; Capture.stop() and Snap.screenOff() turn it off.

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

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

When To Use It

In detection flow, refresh the screen with Snap.screenRefresh() first, then narrow the search area and confidence using Region and FindParam.

Parameters and Return

Takes no arguments. Returns a boolean (true or false).

Best Combined With

It is typically combined with Snap, Region, Asset, and FindParam; you can feed the result into quickTap(), click(), or a follow-up OCR step.

Example Usage

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

lua
Try in Editor →
local ok = Capture.isRunning()

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 →
local ok = Capture.isRunning()

Simple

Wraps the base call with minimal flow control.

Simple
lua
Try in Editor →
local stepOk = true
local ok = Capture.isRunning()
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()
  local ok = Capture.isRunning()
end)

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

Detailed

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

Detailed
lua
Try in Editor →
-- In detection flow, refresh the screen with Snap.screenRefresh() first, then narrow the search area and confidence using Region and FindParam.
local function run_isrunning_step()
  local ok = Capture.isRunning()
end

local ok, err = pcall(run_isrunning_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 →
Snap.screenRefresh()
local ok = Capture.isRunning()

local target = Region():find(Asset.image("target"), FindParam.timeout(3000))
if target then
  quickTap(target)
end
toast("Detection step completed")
