Thank you for this video! I had been bashing my head against the wall trying to figure out why my Set Array Elem wasn't doing ANYTHING. Print screen after print screen... After watching half your video i realized that i am a very absent minded person who forgot to give the array any elements at all. Kinda hard to store data with out any array elements... sigh
Nutritious teaching, your other videos have helped many newbies like me. Thank you for your teaching. Thank you very much for making it easier for us to understand these more delicate functions.
+Joshua Schafer Should be no problem to do the Minimum Area Rectangle video but where is the Macro at? It's not in the normal BP Event graph so is it specific to another part of the engine?
Thanks! I type in '2d grid' into the blueprint editor and it pops up as '2d grid execution macro'. If it's not there it's probably an add-on I installed or something :p
when i use this note it always reset all other indexes to 0 expect this i add this index works well. when i edit an other index the same alle other indexes of the array get the value 0.Any idears?
Could you please detail what you mean at 1:47 ? I think I have precisely this issue : I am updating an array with a value I get from it, modify, and put back in.
Do you mean looping thru an array and modifying it? Basically, don't use a set array or any other node that changes and array while you are in the middle of it. Thank of getting data from an array when you loop over it and not changing it mainly. If you are not looping then you are fine as you are just getting and changing that one thing and not working with other values from the array at that same time. If you want to change an array in the middle of it, for example taking all values and or deleting some of them then what you might want to do is make a copy of your array (just use a set node and set a new variable value to the same as your old array) so you have 2 copies of the same array. Then you want to put your original into the for each loop input and whenever you make changes, like set array element or delete or something like that you would make the changes to the copy (it would be the input on the change node). Then when you are done looping over everything you can set the old array (your original) to the values in the new array (the opposite of what we did at the start to copy them. This prevents the array your are looping over from changing while you are looping over it if that makes sense.

AWESOME. Thank you!
Very very importants, very thanks!
Awesome information, man. Can you please do a video about 'minimum area rectangle' and '2d Grid Execution Macro' nodes?
