This would be a very useful addition to Flowlab’s behaviors, as it would make it significantly easier for certain situations where you want something to be more likely to occur than something else. For example:
A chest you come across in an rpg, has a chance to spawn 3 different keys:
Blue Key (Blue key will have a 50% chance of spawning)
Red Key (Red key will have a 20% chance of spawning)
Yellow Key (Yellow key will have a 30% chance of spawning)
You actually can do something like with the random behavior, but it can get tedious at times.
