Check all enemies are dead?

I'm stuck!

I'm making an Asteroids clone and all is going well except I'm not sure on how to check all the asteroids are dead so I can restart the level. Does anyone know of a way to check this? Cheers.

EDIT* Just pointing out that there are around 6 different objects as Asteroids and several instances of those objects that can be 'alive' at any one time. If it was 1 or 2 things to check the state of I'd be OK, it's the fact there can be so many things to check that's throwing me.

From my own experience the best way is to add a global variable that you add 1 to every time a big asteroid and smaller asteroids spawn and subtract one from it every time one is destroyed. When the variable is at zero you can set a new level to start.

N.b. I currently use two global variables for this one counting up to a set point and one counting down. to make sure there are no mistakes but i am dealing with a more complex tower defence game.. one variable should be plenty for you :)

Great idea! I'll give that a try now. Cheers.

There's count expression for each objects, check this example:

count might be a better way of doing it now i look at that capx. Might switch to using .count myself.

if theres multiple objects that make up your enemies then make an enemy family then make sure the families .count is 0
