TIMELINE IDs
When creating a TIMELINE_EVENT, the timeline ID must be a user defined long constant. The NetLinx
compiler will not semantic check the type of the timeline ID, and the NetLinx runtime system will
attempt to cast the contents of the timeline ID constant, to a long constant. A runtime error will occur if
the cast is unsuccessful.
Here's an example of
TIMELINE code:
DEFINE_VARIABLE
CONSTANT LONG TimelineID_1 = 1
CONSTANT LONG TimelineID_2 = 2
CONSTANT LONG TimelineID_3 = 3
CONSTANT LONG TimelineID_4 = 4
LONG TimeArray[4] =
{
1000, // 1 second
2000, // 2 seconds
3000, // 3 seconds
4000 // 4 seconds
}
DEFINE_START
TIMELINE_CREATE
(TimelineID_1,TimeArray,LENGTH_ARRAY(TimeArray),TIMELINE_RELATIVE,TIMELINE_REP
EAT)
TIMELINE_CREATE
(TimelineID_2,TimeArray,LENGTH_ARRAY(TimeArray),TIMELINE_RELATIVE,TIMELINE_REP
EAT)
TIMELINE_CREATE
(TimelineID_3,TimeArray,LENGTH_ARRAY(TimeArray),TIMELINE_RELATIVE,TIMELINE_REP
EAT)
TIMELINE_CREATE
(TimelineID_4,TimeArray,LENGTH_ARRAY(TimeArray),TIMELINE_RELATIVE,TIMELINE_REP
EAT)
DEFINE_EVENT
// typical TIMELINE_EVENT statement
TIMELINE_EVENT[TimelineID_1] // capture all events for Timeline 1
{
SEND_STRING 0,"'TL ID = ', itoa(timeline.id),', sequence =
',itoa(timeline.sequence)"
}
// example of "stacked" TIMELINE_EVENT statements
TIMELINE_EVENT[TimelineID_2] // capture all events for Timeline 2
TIMELINE_EVENT[TimelineID_3] // capture all events for Timeline 3
TIMELINE_EVENT[TimelineID_4] // capture all events for Timeline 4
{
SEND_STRING 0,"'TL ID = ', itoa(timeline.id),', sequence =
',itoa(timeline.sequence)"
}
// end
