a - b: Difference between revisions

Revision as of 21:59, 2 May 2006

Operand types:

a: Number or Array

Type of returned value:

Number or Array

Description:

For numbers: a minus b.

For arrays: Contents of array b removed from array a.
See also. Array

Examples:

Number
_sum = 10 - 7 ............ _sum is 3

Array
_result = [1,2,2,player,"String"] - [2,player,player,"String"] ............ _result is [1]

Comments:

Note that this way of removing elements from an array will not work if those elements are themselves arrays.

For example

[ [0,0,0],[1,1,1],[2,2,2] ] - [1,1,1]

Will not remove the element [1,1,1] from the first array.

A more practical example: [ getPos unit1, getPos unit2, getPos unit3] - getPos unit3

Will not remove the position of unit3 from the first array.
