What if i need to use decimal percentages on the rarities?

[pietrociatta]

I'm trying to put like Background#5.5 value, by changing to const exp = /#(\d*\.\d{0,2})/;
But it seems not working, how can i use decimal value as rarities, also 0.3 for example.

@pietrociatta thanks for the question, this comes up a lot.

Decimals are not supported in file name's rarity weights.
If you need decimal percent rarity, you can calculate them by using a higher total weight number.

reminder, weight's in a folder do not need to add up to 100, it can be anything. Percentage at the time of generation is calculated as

percent change = file weight / total sum of weights in folder

to have a "decimal percent chance" for a given file, you can have the total weights add up to 1000.
Then, some-file#5.png would have a 0.5% chance of being chosen

you really should put this in the readme, I had to look through all the code and figure this out when it could have simply been said in the readme that this is how it works.
