getTokens() Function

 Note: This function can only be used in a Trusted Macro

• Introduced in version 1.3b48

Gets a list containing the ids of all the tokens on the current map, or all the tokens that match the specified conditions. The type of the value returned depends on the delimiter parameter.

Usage

getTokens()

getTokens(delim)

getTokens(delim, conditions)

Parameters

• delim - The delimiter used to sepearate the values in the String List that is returned, defaults to ",". If "json" is specified, a JSON array is returned instead of a String List.
• conditions - A JSON object that contains various conditions that the tokens must fullfill. All conditions are optional.
  • setStates - A JSON array of states the token must have. Any token which does not contain all of these states in the true condition will be removed from the returned list.
  • unsetStates - A JSON array of states the token must not have.
  • npc - If the token must be a NPC, set to true(1) or false(0).
  • pc - If the token must be a PC, set to true(1) or false(0).
  • selected - If the token must be selected, set to true(1) or false(0).
  • impersonated - If the token must be impersonated, set to true(1) or false(0).
  • current - If the token must be the current token, set to true(1) or false(0).
  • owned - If the token must be owned by the current player, set to true(1) or false(0).
  • visible - If the token must be visible to players, set to true(1) or false(0).
    • note: GMs will be able to see everything, to test if a token is visible to a player with this function, you must have "Show as a Player" enabled. In addition, this appears to only affect the "visible to players" flag - VBL and Fog of War do not seem to affect this.
  • layer - A JSON array of layer names, or a single layer name as a string. Note that a token not on any of the listed layers will be removed from the list returned (added in 1.3b77)
  • range - A JSON object with range conditions, all range conditions are optional.
    • token - The id or name of the source token that the distance is measured from, defaults to the current token.
      • note this parameter is needed if you are calling your macro from a macroLink and aren't impersonating a token
    • distancePerCell - If the Distance Per Cell multiplier should be used, set to true(1) or false(0).
    • from - A number specifying the minimum range that a token needs to be from the source.
    • upto - A number specifying the maximum range that a token can be from the source.
    • metric - The distance metric to use, if it is not specified the default from the users preferences is used.
  • area - A JSON object containing specific area information.
    • token - An optional field that contain the name or id of the token that resides at the center of the area. Defaults to the current token.
    • offsets - A JSON array of JSON objects that specify each individual cell that make up the area.
      • x - The relative x position of the cell in relation to the token field. Measured in cells.
      • y - The relative y position of the cell in relation to the token field. Measured in cells.

The movement metric in range specifies the movement metric use, the metric can be one of the following strings

• NO_GRID - The grid is ignored and straight line distance between the tokens is returned.
• ONE_TWO_ONE - First Diagonal movement costs 1, second 2, and so on (Square grid only).
• ONE_ONE_ONE - Diagonal movement costs a single square (Square grid only).
• MANHATTAN - Diagonal movement costs 2 (Square grid only).
• NO_DIAGONALS - No diagonal movement is allowed (Square grid only).

Example

You can use the following code to print out the ids of all of the tokens on the current map.

[h: ids = getTokens()]
[foreach(id, ids, "<br>"): id]

Find and return a JSON Array containing all NPC tokens that are with 2 squares or hexes.

[h: cond = '{ range: {upto:2, distancePerCell:0}, npc:1 }']
[h: ids = getTokens("json", cond)]

Modifying the above example to exclude dead tokens.

[h: cond = '{ range: {upto:2, distancePerCell:0}, npc:1, unsetStates:["Dead"] }']
[h: ids = getTokens("json", cond)]

Get all of the non dead NPC tokens in the square above, below, left, and to the right of the token, using the area option.

[h: areaOffsets = '[ {x:1, y:0}, {x:0, y:1}, {x:-1, y:0}, {y:-1, x:0}]']
[h: area = json.set("{}", "offsets", areaOffsets)]
[h: cond = json.set("{}", "area", area, "npc", 1, "unsetState", "['Dead']")]
[h: ids = getTokens("json", cond)]

The same could be achieved using the range option with NO_DIAGONALS metric.

[h: cond = '{ range: {upto:1, distancePerCell:0, metric:"NO_DIAGONALS"}, npc:1, unsetStates:["Dead"] }']
[h: ids = getTokens("json", cond)]

Version Changes

• 1.3b49 - Added json delimiter option.
• 1.3b51 - Added conditions parameter.
• 1.3b55 - Added metric option to range option in conditions parameter.
