Graphics

I'm trying to duplicate group of objects in my scene and distribute them randomly around the screen. The number of copies is pulled from a database.

is something like this possible?

to start I am trying to create object using this code:

OnOnline:

dim quad as xpBaseObject

dim j as Integer

for j = 1 to 12

Self.CreateObject("Quad", quad)

quad.Name = "q"

quad.PosX = 10*j

next

I get no errors - but I also don't see 12 quads? Any suggestions would be appreciated!

thanks!

If you don't assign a material to the quads they will just be invisible/transparent.

Use .SetMaterial to assign a material after retrieving it with engine.GetMaterialByName.

Thanks Brian!

Another question: I have an xml file with unknown number of elements

1. is there a way to find the total number of elements using scripts?

2. is there a way to step thru the elements using script (ex: can I script dataliq keys values?)

thanks again!

Ronen, you can not query the number of elements. If you exceed the number of elements there is an option to have the indexes wrap. E.g. If you query the 6th element of a datalinq with only 5 elements you'll get the first again.

In recent versions (5.4 and above) You can script datalinq keys to step through a datalinq. One approach would be to put a script event on the scene director that increments the value of the datalinq key and does a RefreshDatalinqs. You could then have a loop event on the scene director to keep looping and advancing the value.

Something like this:

dim keys as xpDatalinqKeys

dim key as xpDatalinqKey

if Scene.GetDatalinqKeys(keys) then

if keys.GetKeyByName("jersey", key) then

key.AsString = (CInt(key.AsString)+1).ToString

Scene.RefreshDatalinq

end if

end if

Thanks Brian, that seems like the way to do it, much appreciated!
