Random Action?

Hey, how do I trigger this....

Event: Whatver
Conditions:
Action:
20% chance to spawn an A
30%chnace to spawn a B
50 chnace to spawn a C

You know what I mean? On acertain event, and want my actions to be random to increase map playability. Thanks for any help. Rep will be given.

Set RandomIntegerVariable = Random number between 1 and 10 (Math - Random Number)

Then use RandomIntegerVariable for the chances (If RandomIntegerVariable equal to or less then 2 then do A, etc etc).

Okay thanks, now I have another question. How do I kill an entire variable array. I will assign units to variable Bandit[1] Bandit[2] etc. How do I kill the entire array with one action?

.. Loop 1 to How many you expect to be in the variable.

For each Integer A from 1 to ExpectedNumber do
Set YourUnitArray[IntegerA] to No unit (Or anything else you want)

Oh wait, you said KILL... you do the same thing but you;
Kill YourUnitArray[IntegerA]
Instead. Same idea, different execution.

i gave rep. for the first help, but I didnt understand that last one. I want to kill my entire array. That's Bandit[1] through Bandit[20} all 20 bandit scum dead in one sweeping motion!

try this.

For each (Integer A) from 1 to (number of units in Bandit()array), do (Actions)

Loop - Actions

Unit - Kill Bandit[(Integer A)]

Hope that makes sense to you.
