My idea is pretty simple: Every action has a “with __% chance section”. For example:
Action I with 30% chance
Action II with 50% chance
Action III with 0.5% chance
If the percentage is showed like this: “.8%” then it will count as 0.8%
Also there will be “Set max persentage possible” button.
Action I has 40% chance
Action II has 25.5% chance
Pressing this button for Action III will set its chance to 34.5%
And we will be able to connect actions by percentage to act together
Action I has 50% chance
Action II has 40% chance
But we can make them activate together with button “connect with action and set percentage”
So we connect Two Actions and set their chance to 100%
If you leave this action setting blank, then it will automatically get 100% chance, if there’s two blank actions, so their chances are 50%, 33.3333…% for three blank action, you get the line.
In the event, it will show like that: Change the value of a global variable GlobalVariable : set to 0 with 57% chance (the percentage has blue color)
