hasLightSource() Function

• Introduced in version 1.3b48

Returns 1 if the Current Token has any light sources that match the criteria passed in or 0 if there are no matches. If no arguments are passed to the function then it will return 1 if any light source is on. If only the first argument is passed it will return 1 if any light source of that light source type is on. If both arguments are passed to the function it will return 1 if the light source with the specified name and specified light source type is on.

Usage

hasLightSource()
hasLightSource(type)
hasLightSource(type, name)
hasLightSource(type, name, tokenRef)
hasLightSource(type, name, tokenRef, mapname)

Parameters

type - The light source type, (e.g. "Generic", "D20"). If "*" is entered, all light sources types are checked. Defaults to "*".
name - the name of the light source. If "*" is entered, all light sources names are checked. Defaults to "*".
tokenRef - Either the token id or Token Name of the token which is checked for light sources, defaults to the Current Token.
Note: This parameter can only be used in a Trusted Macro.
mapname - The name of the map to find the token. Defaults to the current map.

Token IDs are unique, but Token Names can be duplicated. Using Token Name when more than one token has the same name can produce unexpected results.

Examples

Check to see if any light source is on.

[h: l = hasLightSource()]

Check to see if a "D20" lamp is on.

[h: l = hasLightSource("D20", "Lamp - 15")]

Check to see if any "D20" light source is on.

[h: l = hasLightSource("D20")

Version Changes

1.5.4 - Added id and mapname parameter options. Changed behavior if type or name are set to "*".
