## DAStatic Functions Relevant to DAEvent Objects

###

AndEvent

DAStatics Class

Creates 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.

###

KeyDown

DAStatics Class

Returns 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.

###

KeyUp

DAStatics Class

Returns 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.

###

NotEvent

DAStatics Class

Creates 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.

###

OrEvent

DAStatics Class

Creates 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.

###

Predicate

DAStatics Class

Creates 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.

###

ThenEvent

DAStatics Class

Creates 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.

###

TimerAnim

DAStatics Class

Creates 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.

###

Timer

DAStatics Class

The same as TimerAnim except that timeout is a non-animated number (a double).

lib.Timer(
timeout
)
