How 2 make enemies spawn randomly, not a set interval!

So lately ive been trying to add a ship that drops a special item but it occurs randomly, And the only thing i have is the Interval seconds, which is SET. I want mine to have random times, like it can occur anytime, not just every second.

Just have every second choose(0,4) for instance, then if the number is, say 4, you have the action happen. The system can randomly pick different numbers every second, but only have the action happen when one of the numbers is picked.

how do you do that? Can you show me a event sheet example of that? im really kindoff a nooby.

Every X Seconds | Spawn Enemy & set next X to int(random(1,6))

so for Every X Seconds you use a global variable, I'll call it xRandomSeconds

Every "xRandomSeconds" do

1) Spawn your enemies

2) System | set "xRandomSeconds" to int(random(1,6)) - now you have a new interval for the next spawn

Here's a simple example: https://dl.dropboxusercontent.com/u/495 ... ntime.capx

Pick a random number (0, 1, 2, 3 or 4) every 0.5 seconds. When 4 is picked, spawn the enemy.

thank you all for your help guys!

i've found a huge problem. once the varible has changed to four, instantly twelve copies of the main enemy spawns behind it, but i only want one to spawn. any help?
