Hey @mathias_2000! Welcome to the forums!

I actually helped someone recently with a very similar system. Check out the thread and see if that helps you out!

Random captureable NPC spawn in set radius around player

Hey downofwar5000! So what you can do here is use a Random in Range (Float) node. You can do something like this: [image] So the “Common” and “Rare” variables are checked. Say you get a 700 and common is set to 500. This will return false for Common, and move on to asking if it’s Rare. This can be chained as many times as you need to have your different rarities!

hey mind-brain,
Thank you very much for your answer ! I will try it tomorrow! do you think it can fit with the base i shared ?

Absolutely! The biggest thing to re-use from this is the cascading numbers, going in one direction.

You would use the “rarity finder” to generate a random number, then use that rarity # to set the Integer you use on your Select node!
