enumFeature()

Owned by Aubergine
Last updated: Feb 01, 2013Version comment
Returns an array of feature objects (like trees and boulders), optionally filtered to a specific looking player...

 

Syntax

var returnValue = enumFeature([viewer[, featureID]]);

Parameters

ParameterTypeMandatoryDescriptionGame version
viewerNumber(error)

List features that a specific player can see (eg. on their sensors), with the player specified by their player ID.

Defaults to me.

You can specify -1 which means "don't filter based on viewer" so you get a list of all features on the map. In more recent Warzone versions you can specify ALL_PLAYERS to get a similar effect.

3.1 Beta 1
featureIDString

(warning) 3.1

(error) 3.2+

Optionally filter the list to features of a specific type as defined by their feature ID.

You can get a list of feature IDs from the first column in features.txt

In Warzone 3.1 RC3 and earlier:

  • If no parameters are specified, defaults to listing everything (no filtering).
  • If the viewer parameter is specified, defaults to listing nothing (everything gets filtered out) unless you specify "" (empty string)

In Warzone 3.2 and above:

  • Defaults to listing all features (no filtering) regardless of whether viewer parameter is specified or not.

3.1 Beta 1

Bug fixed in Warzone 3.2
