How do I create probability?

Hello,

I'm building random levels generator, and I wander how can I create probability of spawning something; should I do it this way, or is it not probability: random (100), is between num A and B ( ex. 30, 70 )? I'd also would like it to change throughout the game. Any thoughts?

Thanks

You're on the right track. If you want to change it, use variables instead of fixed numbers in place of A and B, you can change those variables in any event.

You could do that. If it's just a probability of happening or not you could just compare with one value.

aka random(100)<40 for a 40% chance.

If you want a probability of more than two things happening you would store random(100) in a variable first. So for example you want A to have a 30% chance and B a 10% you could do:

global number rand=0

every tick

--- set rand to random(100)

rand is between 0 and 30

--- do B

rand is between 30 and 40

--- do B

Cool, thanks for clarification.
