Setting possibilities/chance

Hi
Hope you are all doing great, I have a simple question... how can someone set possibilities/chances in the game, an example:
If the player does something in particular, set a 50% chance for a scene to apear, if the user doesn't do something in particular, set a 25% chance for a scene to apear
I hope is something simple to do
Thanks!!

I use an RNG with a list of outcomes for this. Probably not the most elegant solution, but it works.
I can give you an example within a day or so.

the simple way is creating a temporary random value and compare.
Code: Select all
def chance_example():
c = renpy.random.randint(0, 100)
if chance_1 < c:
# trigger the event

In addition to what Kia said, you could also do it like this, I guess...
Code: Select all
default userdidSomething = False
default probability = renpy.random.random()
if probability >= 0.50 and userdidSomething:
do something...
elif probability <= 0.25 and not userdidSomething:
do something...

You could also try this one, just found it on google.

The way I'm doing it isn't much different from how Kia suggested, but I'll post it anyway since I have it here.
Code: Select all
default result = 0
label start:
$ result = renpy.random.randint(1, 16)
if result in [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]:
# 100% chance
elif result == 0 or is > 16:
"ERROR"
to get a specific chance value, omit some of the numbers in the list, for example, removing half of them gives a 50% chance of renpy.random creating an integer in the list.
