    Posted 11-07-2024 05:30

    Hi everyone, 

    There is a primitive called LINES in xpression. How can i manuplate the x, y & z numbers of the 'points' inside the lines thru external data? in other words how can i control the x, y & z numbers externally thru datalinq?

    Yes you will find references in the SDK how to control them. 

    I have an example here that animates, I cannot give you the project as it belongs to a client but here is a script I wrote. 

    OnOnline

    dim Lines1, Lines2 as xpLinesObject
    dim count, tally as xpTextObject
     
     
    self.GetObjectByName("Lines1", Lines1)
    self.GetObjectByName("Lines2", Lines2)
    self.GetObjectByName("Tally", tally)
     
    tally.Text = "1"
     
    Lines1.SetCurrentList(0)
    Lines1.ClearCurrentList
     
    Lines2.SetCurrentList(0)
    Lines2.ClearCurrentList

    this was on a Scene Director script 

    dim Lines1, Lines2 as xpLinesObject
    dim count as xpTextObject
     
     
    scene.GetObjectByName("Lines1", Lines1)
    scene.GetObjectByName("Lines2", Lines2)
    scene.GetObjectByName("Count", count)
     
    dim c as integer = count.Text
     
    dim tPoint, ctPoint as xpTextObject
     
    dim x as integer = 1180 / c
    dim y as integer = 10
     
    Lines1.SetCurrentList(0)
     
    Lines1.ClearCurrentList
     
    Lines1.BeginUpdate()
    Lines1.AddPoint(0, 1000, 0, 5)
    dim i as integer
    for i = 1 to c
    scene.GetObjectByName("tTicket" & i, tPoint)
    dim t as integer = tPoint.Text
    engine.DebugMessage(tPoint.Text, 0)
    Lines1.AddPoint(i*x, t*y, 0, 5)
    Next
    'Lines1.AddPoint((c+1)*x, 0, 0, 5)
    Lines1.EndUpdate()
     
     
     
    Lines2.SetCurrentList(0)
     
    Lines2.ClearCurrentList
     
    Lines2.BeginUpdate()
    Lines2.AddPoint(0, 1000, 0, 5)
    for i = 1 to c
    scene.GetObjectByName("ctTicket" & i, ctPoint)
    dim t as integer = ctPoint.Text
    Lines2.AddPoint(i*x, t*y, 0, 5)
    Next
    'Lines2.AddPoint((c+1)*x, 0, 0, 5)
    Lines2.EndUpdate()
