Hello, this topic is conected from [this].(Timer still iterate even when it crash. - #3 by morethanamotion) I’m happy to share to you that I unexpectedly discover how to simultaneously cast object using an “enterFrame” listener as replacement for timer.performWithDelay()

Using the “enterFrame” Runtime Event listener, I calculate the event.frame’s %(modulo) to 100 under the local base variable, and every time that base is equal to 0, a rectangle is casted:

```
local castBullet
local bullet
local function Berserk( event )
local goframe = event.frame
local base = goframe % 100 ---> change this value to have faster iteration. istead of 100, try lower or higher. But I sugest, it is much better if it is divisible by 5 (:
if ( base == 0 ) then
bullet = display.newRect(display.contentCenterX, display.contentCenterY, 100, 50)
bullet.rotation = math.random(0, 360)
end
local rotationInRadians = bullet.rotation*math.pi/180
local movementPerFrame = 3
local xMovement = math.cos(rotationInRadians)*movementPerFrame
local yMovement = math.sin(rotationInRadians)*movementPerFrame
bullet.x = bullet.x + xMovement
bullet.y = bullet.y + yMovement
end
Runtime:addEventListener("enterFrame", Berserk)
```

Now, even you hold down the minimize or close(x) button of the simulator, it will pause but it will still continue from the time it paused when you released.

I hope that it helped you, **You’re welcome in advance.** I will be very happy for all opinions, suggestions, advice and more. **Thank you very much**
