How do I activate random groups?

I need to activate random groups after collision detected... Thanks

Create a variable for that.

After the collision assign a random value for this variable. Something like

On collision with object > Set var to int(random(10))

After assigning a value for your variable set a condition activating the group you want for different values.

For instance

Variable = 0 > Activate group A

variable = 1 > Activate group B

Variable = 2 > Activate group A and B

Hope this helps

Create a series of groups postfixed with numbers, like:

"Foobar_1"

"Foobar_2"

. . .

..."Foobar_10"

Then go:

Activate Group: "Foobar_" & str( int( random(1,10) ) )

Great, i solve it, thanks to all!
