hasLightSource

Function hasLightSource

 Note: This refers to a proposed change that has not been implemented in the main code base yet.

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

[h: hasLight = hasLightSource()]
[h: hasLight = hasLightSource(type)]
[h: hasLight = hasLightSource(type, name)]

Where

• type is the light source type, (e.g. "Generic", "D20")
• name is the name of the light source.

If delim is specified then it is used to separate the values in the list, if it is not specified then it defaults to ','.

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")]
