Spawn help please?

Hi guys, I’m new to Corona/Programming, and was hoping I could get a little help from the senior programmers if you will.

I have 2 objects falling from the top, my countown functions as soon as they spawn and changes to Go and Win/Fail etc.

Each time I try to change the total amount of objects to spawn, it won’t register and spawns the same number for each.

For example;

O1 = 0  
O2 = 0  
time\_remain = 10  
time\_up = false  
  
total\_object1 = 4  
total\_object2 = 2  
  
ready = true

That is the top of the page, my timer is linked to Object1, is it supposed to be linked to both?

[code]
local function spawnObject()

local object1= display.newImageRect(“XX.png”, 40, 40)
object1:setReferencePoint(display.CenterReferencePoint)
object1.x = 35; object1.y = 80

–increment O1 for every object1 created
O1 = O1+1

object1:addEventListener(“touch”, object1)

physics.addBody(object1, {density=0.3, friction=0.6, radius=20} )

tmr = timer.performWithDelay(20, spawnObject, total_object1)[/code]

If someone could help me with a table or code that could allow me to control the number of spawn, I’d be extremely grateful.

It’s not clear where you’re calling performWithDelay from, and how and where you’re (presumably) changing the value of total_object1. Maybe we need to see the rest of the relevant code. [import]uid: 3953 topic_id: 7811 reply_id: 27734[/import]

I found this helpful when I was looking at a class based system for spawning objects:

Going to try something - will post back as soon as possible.

Thank you for the reply, Mark.

Edit: If anyone could start me off on a table to control the spawns of multiple objects(number of spawns), I’d be highly appreciative - I just can’t figure it out.

Thank you, Crssmn.
