Examples

Example 1: Save a screenshot which will get used for the next savegame.

createScreenshot()

Example 2: Clear the previously saved savegame screenshot.

createScreenshot("", {flags=1, clear = true})

Example 3: Save a screenshot to a folder. If a file with the same name already exists, it will be overwritten. Be aware that the default save location is the game directory, which may be write-protected.

createScreenshot("screenshots/my_screenshot.png")

Example 4: This expanded example uses the "lfs" file system library to check for a "screenshots" folder inside the user directory and creates it if it doesn't exist.

-- Define a screenshot folder inside the user directory
local screenshot_folder = localAppDir .. "screenshots"

-- Function to check if a folder exists
function folderExists(strFolderName)
  if lfs.attributes(strFolderName:gsub("\\$",""),"mode") == "directory" then
    return true
  else
    return false
  end
end

-- Try to create the screenshot folder, if it doesn't exist
if not folderExists(screenshot_folder) then
  lfs.mkdir(screenshot_folder)
end

-- If the screenshot folder exists, save a screenshot with timestamp
if folderExists(screenshot_folder) then
  local time = os.date("%Y-%m-%d_%H-%M-%S")
  createScreenshot(screenshot_folder .. "/screenshot_" .. time .. ".png")
end
