A cluster is a grouping of maps, usually, but not necessarily, separated by story elements. This should not be confused with episodes.

Block syntax

cluster <number> { properties }

Assigns the properties to a cluster with the specified number. Numbers should be greater than or equal to 1.

Block properties

• exittext = "<text>"
• exittext = lookup, "<string>"

When exiting a level with transitions to a different cluster. This message will be displayed. Use lookup to use a message from the LANGUAGE lump.

• exittextislump

The exit text is a lump containing a message to display.

• exittextismessage

Instead of showing an art screen. Just pop up a message box. Used for the Spear of Destiny Demo end screen for example.
