Choose a random value out of four options??

Elfizm

Hello everyone

Can I have a rule that chooses a random value from four numbers that are given? Eg. If I have 4,5,2,7 can I make it choose one of those four numbers?

Or is this a complicated thing? Just wanted to make sure i wasn't missing something simple!

Thanks

Put the four numbers into a table, call it say randomNumberList. Four rows, one column. When you want to choose one randomly, assign an attribute, for example diceRoll, a random number from one to four. Then set the attribute, for example Result, you want to be one of the four numbers to tableCellValue.randomNumberList,diceRoll,1).

Thanks so much my way was a bit longer and this is so simple it's embarrassing I didn't think of it.
Made a demo and it works great

@TesseractEngine or anyone

So here is a quick info if a game. I have boxes, heaps if them, but only four can be selected. They are choosen randomly. Once selected they becomes used and can not be opened again but can still be selected.

So how would I make it choose a random value excluding the ones that are used. So if I select box 2, 5, 6, and 7. It will choose a random one using method suggested.

But if a new lot of four are selected and it's. 4, 5, 8, 9
How can I make it only to choose a random on out of 4,8, and 9 even though 5 is selected.

Hope that makes sense

Thanks
