Expression for Weighted Randomization
« on: September 27, 2022, 12:32:34 AM »
I'm trying to write an expression or node group that will let me select from input segments randomly, but with weights for added control.. I could use a selector and double up inputs but that doesn't allow as much control + gets pretty clunky. Does anyone have any solutions? Here is the solution I'm trying to translate to Railclone (and my poor attempt is there too).

HI,

If it's segments that you're trying to randomise, could you use the Random node? It already has built-in probability settings (called Presence)



Cheers,

Well this is embarrassing  ;D I had no idea that existed.

Thank you so much!
