Hello, I'm making a randomizing system like this:

The player reaches a point in the conversation with an NPC involving a group Node with a number of branches. After the player goes through every branch at least once, I want the conversation to transition into a math.random between all branches.

How can I do that? My original line of thought was to make a local variable and change it every time a branch ends, and after it reaches the highest possible value, make the dialogue go through a separate Node with math.random.

That'll work. Let's say you have 3 nodes: A, B, C. You could define a variable "branchesVisited" initially set to zero. Then set up the nodes like this:

• Group Node linked to A, B, C: Condition: branchesVisited==3, Script: RandomizeNextEntry()
• A: Condition: branchesVisited==0 or branchesVisited == 3, Script: branchesVisited=1
• B: Condition: branchesVisited==1 or branchesVisited == 3, Script: branchesVisited=2
• C: Condition: branchesVisited==2 or branchesVisited == 3, Script: branchesVisited=3

Make sure the group node is first in the list. (Inspect the previous node and check the Links To: section at the bottom.)

EDIT: Updated conditions.

Hi, Tony! Thanks for the reply!

I ran a few tests and I think that this way only works if I wanted to randomize between nodes located after the branches in question. What I want to do is actually rerun the branches, like this:
The Group Node is supposed to randomize between the branches below it after going through them all at least once. I tried setting a different variable for this, but right now the only solution I can see is making two group nodes - one that gives the branches a pass before they are all read and then another one that acts as the randomizer, after branchesVisited is equal to the number of branches.

Good point. I updated the conditions in my previous reply. I think that should work the way you want.

Thanks! That solved it - at least for now, I think.

Sound good! If you come up with any cases that you'd like to handle that the current conditions don't handle, just let me know.
