Your question is a big vague…

But you would do the following :

pause any active transitions
stop players/enemies moving
etc

Use gamestates its the easiest way.

Have a variable like :

  
local paused = false  
  
--and in all your functions simply do (at the top of them)  
  
if paused == false then  
--do whatever  
end -- put the end at the end of the function

That way your functions will only execute if the paused variable is false.

@dev.m.hantash

You don’t fire the event yourself, it’s fired by the system automatically.
You just need to listen for the event like david97 has done in his example with a Runtime:addEventListener call.

One thing to note is that the event itself doesn’t pause timers and transitions for you. You have to write that code yourself in the event handler.

Corona doesn’t support pausable timers and transitions out-of-the-box just yet, but
if you have a look in the Code Exchange, you can find some lua modules that can do these things.

To pause on system events, look up the System Event API’s and try:

[lua] function onSystemEvent( event )
if( event.type == “applicationExit” ) then
–Save App data
end

if( event.type == “applicationSuspend” ) then
–Save App data & state variables
–Suspend timers & functions
end

if( event.type == “applicationResume” ) then
–Load App data & set state variables
–Resume timers
end

if( event.type == “applicationStart” ) then
–Load App data, initiate app
end
end

Runtime:addEventListener( “system”, onSystemEvent ) [/lua]

One method to terminate your app is to use os.exit()

timer.pause( timername )
timer.resume( timername )

Should be in the new general release that came out today. Mods correct me if I’m wrong. I have been using it in the daily builds and it works well. [import]uid: 31262 topic_id: 17102 reply_id: 72421[/import]
