DAStatic Functions Relevant to DAEvent Objects
DAStatics Class
AndEventCreates an event that occurs only when the two given events happen simultaneously. The event time for the new event is when both of the given events occur.
lib.AndEvent(
first,
second
)Parameters
- first and second
- The DAEvent objects.
Return Values
Returns a DAEvent object. When the event occurs, it produces a DAPair. The first member is the event data returned by the first event. The second member is the event data returned by the second event.
DAStatics Class
KeyDownReturns a DAEvent when a specific key is pressed. This is a state-transition event.
lib.KeyDown(
keyCode
)Parameters
- keyCode
- This is a number (a long). See the table below for information about key codes.
Return Values
Returns the DAEvent object. This event produces no data.
Remarks
The following table lists the hexadecimal values for all the special keycodes. The pattern for each key is 0x10000 plus the win32 scan code.
Key KeyCode PGUP 10021 PGDN 10022 END 10023 HOME 10024 LEFT 10025 UP 10026 RIGHT 10027 DOWN 10028 INSERT 1002D DELETE 1002E NUMPAD0 10060 NUMPAD1 10061 NUMPAD2 10062 NUMPAD3 10063 NUMPAD4 10064 NUMPAD5 10065 NUMPAD6 10066 NUMPAD7 10067 NUMPAD8 10068 NUMPAD9 10069 MULTIPLY 1006A ADD 1006B SEPARATOR 1006C SUBTRACT 1006D DECIMAL 1006E DIVIDE 1006F F1 10070 F2 10071 F3 10072 F4 10073 F5 10074 F6 10075 F7 10076 F8 10077 F9 10078 F10 10079 F11 1007A F12 1007B F13 1007C F14 1007D F15 1007E F16 1007F F17 10080 F18 10081 F19 10082 F20 10083 F21 10084 F22 10085 F23 10086 F24 10087 DAStatics Class
KeyUpReturns a DAEvent when a specific key is released. This is a state-transition event.
lib.KeyUp(
keyCode
)Parameters
- keyCode
- This is a number (a long). For a list of special keycodes, see KeyDown.
Return Values
Returns the DAEvent object. This event produces no data.
DAStatics Class
NotEventCreates an event that occurs when the given event does not occur. This is useful for creating combined events that occur only if the given event is not also occurring. For example, an event that occurs when the left mouse button is down and the right button is not down.
lib.NotEvent(
ev
)Parameters
- ev
- The DAEvent object.
Return Values
Returns the DAEvent object. This event produces no data.
DAStatics Class
OrEventCreates an event that occurs when either one of the given events occur. The event time for the new event is when either the first or second given event has occurred.
lib.OrEvent(
first,
second
)Parameters
- first and second
- The DAEvent objects.
Return Values
Returns a DAEvent object. Its data is the event data of either the first or second event.
Remarks
If both events occur at the same time, the first will be chosen to fire. For example, if you attach a notifier to first and second and the events occur at the same time, only the notifier of first will get called.
DAStatics Class
PredicateCreates an event that occurs when the value of the given DABoolean behavior changes from FALSE to TRUE. Note that, because of implementation dependencies and the potential for aliasing, the system cannot always detect when a DABoolean behavior becomes TRUE.
lib.Predicate(
bool
)Parameters
- bool
- The DABoolean object.
Return Values
Returns the DAEvent. This event produces no data.
DAStatics Class
ThenEventCreates an event if e2 occurs after e1. The event time of the new event is the time of the second event.
lib.ThenEvent(
e1,
e2
)Parameters
- e1
- The first event, that, when it occurs, triggers the second event.
- e2
- The second event, caused by the occurrence of the first event.
Return Values
Returns the DAEvent object. Its event data is the time the second event fired and a DAPair containing the event data for both events.
DAStatics Class
TimerAnimCreates an event that occurs when the specified time has elapsed.
lib.TimerAnim(
timeout
)Parameters
- timeout
- The DANumber object that controls when the timer fires. This must be an animated number
Return Values
Returns the DAEvent object. This event produces no data.
DAStatics Class
TimerThe same as TimerAnim except that timeout is a non-animated number (a double).
lib.Timer(
timeout
