function getOpenedProcessID() : Integer

Returns the process ID of the currently opened process in Cheat Engine. If no process is open, returns 0.

Note: getOpenedProcessID() does not return 0 after a process was closed. It will still return the previous ID, even if the process has been terminated. To check if the process is still available, use readInteger(process).

Function Parameters[edit]

<none>

Returns[edit]

Integer — The process ID of the currently opened process, or 0 if none.

Examples[edit]

 1 local pid = getOpenedProcessID()
 2 if pid ~= 0 then
 3   print("Current process ID:", pid)
 4   local check = readInteger(process)
 5   if check == pid then
 6     print("Process is still the same and available.")
 7   else
 8     print("Process has changed or is no longer available.")
 9   end
10 else
11   print("No process is currently open.")
12 end
