How do you play certain event by small possibility?

I know how to play an event by 50percent and 25percent chance but can you make it happen by for ex. 7 percent? help would be appreciated!

There’s lots of ways to pull it off! I used to use a custom macro that went a bit like this. I’d offer the macro but I hadn’t used it in forever. However this works for simple 7/100 chance. There’s better ways to pull this off but this is an easy one if your scale is straightforward.

Is that ‘append’ used only for showing purposes? (I’m noob sorry)

Yep, the only part you need is the part I squared in red. The print was just proof it works. It’s a simple operation but I usually proof test what I tell people here in case I overlook something. Still entirely possible I overlook things though! I do recommend making it a macro if you use this often.

This is good for simple operations, but if you need weighted randomness or say a drop rate system you’ll need to use a different way.

(Last question sorry!)


just to make sure, so is this correct that I overlap the triggerbox, an event occurs by 14% chance?

Hum, I guess you have 86% chance of firing the event. You must use a value of 86 for your int var.
You could alternatively use the node “random bool with weight” that goes from 0 to 1 (100%) . A weight of 0.07 will fire at 7% chance

You got it! As long as the value in that variable Percent 14 is 14.

Indeed I’ve mistaken the sign :sweat_smile:
