Changeset 7271 for code/trunk

Timestamp:

Aug 30, 2010, 8:07:38 PM (14 years ago)

Author:

Message:

There is no such word as "casted".
Also inserted 4 static_casts and replaced dynamic_cast with orxonox_cast in WeakPtr and SmartPtr.
Moreover found some weird code in Iterator.h with casting. Casting a NULL pointer always yields another NULL pointer.

             'simultaniousTriggerers':   The number of simultanious triggerers limits the number of object that are allowed to trigger the MultiTrigger at the same time. Or a little more precisely, the number of distinct objects the MultiTrigger has 'triggered' states for, at each point in time.
             'mode':                     The mode describes how the MultiTrigger acts in relation to all the MultiTriggers, that are appended to it. There are 3 modes: 'and', meaning that the MultiTrigger can only be triggered if all the appended MultiTriggers are active. 'or', meaning that the MultiTrigger can only triggered if at least one of the appendend MultiTriggers is active. And 'xor', meaning that the MultiTrigger can only be triggered if one and only one appended MultiTrigger is active. Notice, that I wrote 'can only be active', that implies, that there is an addtitional condition to the activity of the MultiTrigger and that is the fulfillment of the triggering condition (the MultiTrigger itself doesn't have one, but all derived classes should). Also bear in mind, that the activity of a MultiTrigger is still coupled to the object that triggered it. The default is 'and'.
-            'broadcast'                 Broadcast is a bool, if true the MutliTrigger is in broadcast-mode, meaining, that all trigger events that are caused by no originator (originator is NULL) are broadcasted as having come from every possible originator, or more precisely as having come from all objects that are specified targets of this MultiTrigger.

             'target':                   The target describes the kind of objects that are allowed to trigger this MultiTrigger. The default is 'Pawn'.
             Also there is the possibility of appending MultiTriggers to the MultiTrigger just by adding them as subobjects in the XML description of your MultiTrigger.
