How does product.probability work?

[matjojo]

This is what the lua-api says about itL

• amount :: float (optional): Amount of the item or fluid to give. If not specified, amount_min, amount_max and probability must all be specified.
• amount_min :: uint (optional): Minimal amount of the item or fluid to give. Has no effect when amount is specified.
• amount_max :: uint (optional): Maximum amount of the item or fluid to give. Has no effect when amount is specified.
• probability :: double (optional): A value in range [0, 1]. Item or fluid is only given with this probability; otherwise no product is produced. Has no effect when amount is specified.

So how would I make a recipe to have a .5 change to give just 1, not a number in between two barriers?

Basically... set amount_min and amount_max to the same number, so if you always want 1, set both to 1, the resultant amount will be between... 1 and 1, and therefore always 1.

Though, I may have used probability on amount before, and I'm fairly use it still works. I may have used amount_min and amound_max without probability too, I can't remember.

alrighty then, thanks a lot

See, I knew I'd used probability with amount and not amount_min/amount_max before, and have it work.
