# Essentially a wrapper for specific message types to make them easier to use. Only supports the interception of a message type once (for good reason - this is supposed to
|
|
# be a utility, not a chain of interceptors inside the existing chain).
|
|
#
|
|
# Plugins that wish to expand the list of available message types (you probably don't) should use the add_interception method - see the item-on-item script for example usage.
|
|
#
|
|
# If you only wish to intercept a message, use the intercept method, e.g.
|
|
#
|
|
# intercept :item_on_item, used_id, target_id, :irreversible do |player, message|
|
|
# # code here
|
|
# end
|
|
|
|
|
|
# Calls the registered interception(s), if applicable.
