Oh, nice to know they can be compared directly. How fast is that tho, aka how bad would it be to loop through a list of elements to find the one matching pair?
And what is the actual element.name of an "unnamed" element, is it <1(int)>, <"1"(string)> or just nil?

Also i often use the names of holding tables, flows etc to see what subtable a button belongs too. E.g. if you have two tables with 10 equal buttons each and want to know which of the two tables a button is in, then i can just do something similar to this:

Code: Select all

if event.element.parent.name == 'table1_name' then
 --dostuff
else if event.element.parent.name == 'table2_name' then
 --dostuff
 end

This feels cleaner than to use string operations to try to extract the information from a prefixed button name like "mymod_maingui_table2_button1". And from my limited understanding of factorio-lua internals it should save some memory if the button's name is just "button1" instead because i don't have to create/split a ton of button names? (Many ppl "on google" suggest string creation is slow in lua.)
