Revision as of 15:03, 18 December 2015
Should there be any comment here or in random about randomly selecting an array element given the rounding rules? Or am I being ridiculous?
e.g.
_myArray select ((random (count _myArray)) - 0.5)
--Mr.Peanut 21:11, 28 September 2006 (CEST)
tmp = [];
val1 = [1,2,3];
val2 = [3,4,5];
tmp = tmp + [val1];
tmp = tmp + [val2];
tmp = tmp - [val1];
not working, why? I've also tried "tmp = tmp - val1;" --MessiahUA 16:14, 19 September 2008 (CEST)
Getting Object data directly from an array of Objects
It appeared that I could only retrieve information about an object in an array by first copying the information to a non-array variable. e.g. 1: <getPosATL myArray select 0;> returned null. e.g. 2: <myVar = myArray select 0; getPosATL myVar;> read without issue. Reason is, I'd forgotten parentheses. getPosATL is expecting an object, not an array, but the code returns no object, only after (myArray select 0) is processed, so use parentheses where they are needed.
