An array of group sizes...

Syntax

Code Block
themeRDark
languagejavascript
linenumberstrue
// size of a group
var size = groupSizes[groupID]<id>]; // will throw error if element missing
 
// next available group ID
var numGroups = groupSizes.length;

Properties

PropertyTypeMandatoryDescriptionGame version
groupID<id>Number(tick)(error)

The ID of the droid group.

This ID is generated when you create a new group using newGroup()Specify the group ID that you want to query the size of (see "Notes" below for important information).

3.2
lengthNumber(error)

Returns the next available group ID, which can be used to create a completely new group.

The groupSizes
TypeNotesGame version
<size>

Number

If the group <id> has been used, it's current size is returned as an integer that is ≥ 0.3.2
undefinedUndefinedThe array element exists, but that group has never been used.3.2
<error>ReferenceErrorThe array element does not exist and therefore it's value cannot be referenced.3.2

Notes

The groupSizes[] global is a "sparse" array – that means there might be gaps in the numbering of it's elements, which means that groupSizes.length is not representative of the number of groups you've actually used.

All elements . As such, itup to groupSizes.length - 1 will be defined, but only groups that have been used will have a numeric value (the others will have a value of undefined).

It's recommended to use the forEach() method when iterating the array (see example below).

Example

The .forEach() method simplifies iteration of sparse arrays – it will skip any undefined elements...

Code Block
themeRDark
languagejavascript
titleIterating through the groupSizes array...
linenumberstrue
groupSizes.forEach( function get(groupSize, groupID) {
	// do stuff groupID has been used, so groupSize will always be ≥ 0
	// any unused groups will be skipped
} );

When you need a new group, you can either use newGroup() or simply add stuff to a group that doesn't yet exist:

Code Block
themeRDark
languagejavascript
titleFast way to find next free group...
linenumberstrue
// add a structure to a new group
var newGroup = groupSizes.length;
 
groupSizes[newGroup]; // ReferenceError
 
groupAdd(newGroup, someStructure);
 

 

Div
classsuggest box
For Warzone 3.1, use groupSize() function instead (it also works on WZ 3.2+

groupSizes[newGroup]; // 1
 
groupSizes.length; // == newGroup + 1

If you want to find the next free group that's already defined, you can do something like this (not recommended):

Code Block
themeRDark
languagejavascript
titleSlower way to find next free group...
linenumberstrue
var
	i = 0,
	nextUnused = groupSizes.length;
 
while (i < nextUnused) {
	(typeof groupSizes[i] != "number") ? nextUnused = i : ++i;
}
 
// 'nextUnused' now contains the numeric ID of the next unused group
 
groupAdd(nextUnused, someObject); // create group by adding someObject to it
