Check if string contains another string unordered

Hello there,

I would explain it with the examle:

The game needs a pattern matching algorithm. E.g. there's a list of all possible patterns as 2d array coordintates (as string):

Here's one possible pattern:

0,1 0,2 0,3 1,1 1,2 1,3

Than I have a set of 2d array coordinates, that I would like to check if it contains a pattern from the list (the string above):

5,4 0,0 0,1 0,2 0,3 0,4 1,1 1,2 1,3

How to check if the 2nd string contains all the pairs from the first string, despite of order of pairs?

You could use the system expression

find(src, text)

Find the first index within src that text occurs, else returns -1.

So if the result of that expression is something else than -1 the pattern exists within the text.

Ah, this will only work if both strings are exactly the same or pairs have the same order. I think may be Regex could help, but the biggest problem here is the order of pairs, the search should be unordered.

If you only want to check if the pair exists within the string they dont have to be the same? if not -1 it exists.

But probably I don't understand what you are trying to accomplish.

Ok, I thought it would be possible to check the whole string at once, but I had to do it for each pair - it works like this.
