Required command

In some blocks you can use required command.

For example:

"data" {
  "exits": {
     "north": {
        "required": "green key",
        "target": "new room",
        "excuse": "I need a key for open door"        
  }
}

In this example, you use required command for a item for inventory ( green key ), but you can use it for three main targets:

Items

• Objects taken and carry on inventory
• Objects taken at least one time
• Objects taken and dropped
• Objects dropped on a specified room

Actions

• Manual transparent user-actions (for example: take items, rooms visited o objects seen).
• Objects looked with a required command, adds automatic *_seen action (for example, table_seen when you look table)
• Rooms visited for first time, adds automatic *_visited action (for example, streetold_visited when you go to streetold for first time)

Vars

• Counters or score reached (for example: when var score is at least 5)
