Random Chance

Type: Branch (Success / Fail)
Category: MATH

Branches by probability. Branch version of Random Bool — combines random generation and branching in a single node.

Properties

Property	Type	Default	Description
Probability	Float	0.5	Success probability [0.0 – 1.0]

Sockets

Socket	Direction	Type
In	Input	Exec
Success	Output	Exec (success — occurs with P probability)
Fail	Output	Exec (fail — occurs with 1-P probability)

Generated code

if __import__('random').random() < 0.5:
    #SUCCESS_PATH#
else:
    #FAIL_PATH#

Typical usage

AI decides to attack or retreat

[On State Enter: FSM ID="ai", State="decide"]
    └── On Enter ──► [Random Chance: Prob=0.7]
                         ├── Success ──► [Set State: State="attack"]
                         └── Fail ──► [Set State: State="retreat"]

Item drop on death

[On Message: Subject="enemy_dead"] → [Random Chance: Prob=0.3]
                                         └── Success ──► [Add Object: Object="item_drop"]

Notes

• Equivalent to Branch + Random Bool, but in one node. Use this when you only need to branch by probability without reusing the boolean value.
