I have 2 dynamic arrays, I need to get the index of specific items of the same value and match their index with items in the second array to get their value, so i can alter the second arrays values. Is there a way to use find with a for each loop?

I don’t understand, if you want to make every index match between two arrays, just set one array to other, or even better just use one array. Surely there is something I am missing here.

Hi,  
Any solution to this?  
Currently I am trying to spawn particle count per particle Index or ID.

Hi Ey4D0,  
This was a couple of years ago. Relating to index creation for golf scoring.  
I am attaching my blueprints in the hope they help. The idea was to find which holes were par 3. Then adjust their index for high handicap players. if you tell me more of what you want to do, I may be able to help.  
Cheers
