(custom) properties are unwieldy?
Posted: Thu Sep 24, 2015 8:07 am
Look at this...
set the p1 of btn id tid to the p1 of btn id tid + 1
It's lengthy to write. frustratingly so if you need to refer to multiple properties multiple times in compare and assign statements.. and inefficient too...
while
add 1 to the p1 of btn id tid
is not valid code.
and this:
put the customProperties of btn id tid into p
add 1 to p["p1"]
set the customProperties of btn id tid to p
The above is a bit faster than the first example... while it looks like it should be slower. That says something about the efficiency of custom property lookups.
LiveCode won't won't optimize lots of serial object lookups either (if you use the name instead of the id it becomes much slower with lots of objects).
Maybe add something like this for efficiency..
put ref btn tname into trefbtn
add 1 to trefbtn["p1"]
or
add 1 to treftbn.p1
Some code to play around with (results here: a:662 b:30 c:24 d:6 e:2):
