Changing Objects and Rooms During the Game

You can change an object's alias, prefix, description and more by altering its properties using the property script command. You can also read tags such as an object's look tag in the same way as you'd read an object property - for example #lamp:look# returns the lamp's look tag.

Some object tags aren't just text, but scripts. These tags can be changed by changing the corresponding action, using the action script command, and you can run the scripts using the doaction command.

In the table below, a tick in the "Read Property" column means that tag can be read by reading it as a property, e.g. the #lamp:look# example above. A tick in the "Write Property" means the tag can be set by setting it as a property, e.g.:

property <lamp; look=This is a nice lamp.>

A tick in the "Action" column means you can set script for the tag using the action command, e.g.

action <lamp; look> picture <lamp.bmp>

If an action is set, that takes priority over an equivalent property.

You can set default prefix, look etc. tags for everything in the game by adding these properties to a define type <default> block.

"Use" Actions

action <object name; use> (script)
action <object name; use 'other object name'> (script)
action <object name; use on 'other object name'> (script)
action <object name; use anything> (script)
action <object name; use on anything> (script)

Are equivalent to changing the following tags, respectively:

use (script)
use <other object name> (script)
use on <other object name> (script)
use anything (script)
use on anything (script)

"Give" Actions

action <object name; give> (script)
action <object name; give 'other object name'> (script)
action <object name; give to 'other object name'> (script)
action <object name; give anything> (script)
action <object name; give to anything> (script)

Are equivalent to changing the following tags, respectively:
