This is an example of dynamic create fxShapeReplicator type object
on both clients and server, will generalte flowers from player's current
position, hope others can find this helpful.

I was looking for a solution to do this, and i found this thread
www.garagegames.com/mg/forums/result.thread.php?qt=18448,
so here we have some example code here.

Some notes:
1. you need to replace shapeFile = "~/data/shapes/Plants/flower.dts";
with your own shape file.
2. to remove object, this may not need commandToclient(%cl, 'doReplicate');
3. you can change fxShapeReplicator to fxFoliageReplicator, it should works
also, but not tested.
4. This is just a testing code.

--------------------------Client code:-----------------------------------------------------

$rshapes = new simGroup(rshapes); 

function clientCmdCreateFlowers(%pos)
{
  schedule(1000, 0, "CreateFlowers", %pos);
}

function clientCmdDoReplicate()
{
  schedule(2000, 0, "startFoliageReplication"); 
  schedule(2800, 0, "startClientReplication"); 
}

function CreateFlowers(%pos)
{
   logMessage("clientCmdCreateFlower:" @ %pos, 1); 
   %flowers = new fxShapeReplicator(Flowers) {
      position = %pos;
      rotation = "1 0 0 0";
      scale = "1 1 1";
      HideReplications = "0";
      ShowPlacementArea = "1";
      PlacementAreaHeight = "25";
      PlacementColour = %pos;
      shapeFile = "~/data/shapes/Plants/flower.dts";
      Seed = "1376312589";
      ShapeCount = "148";
      ShapeRetries = "80";
      InnerRadiusX = "0";
      InnerRadiusY = "0";

      ShapeScaleMin = "0.43 0.43 0.43";
      ShapeScaleMax = "1.18 1.18 1.18";

      ShapeRotateMax = "0 0 0";
      OffsetZ = "0";
   };
   rshapes.add(%flowers); 

}

function clientCmdRMFlowers()
{
  schedule(100, 0, "rmFlowers");
}

function rmFlowers()
{
   %count = rshapes.getCount(); 
   logMessage("rmFlowers:" @ %count, 1); 
   for(%i=0; %i<%count; %i++) 
   {
       %obj = rshapes.getObject(%i); 
       logMessage("rmFlowers:" @ %obj, 1); 
       rshapes.remove(%obj); 
       %obj.schedule(10, "delete"); 
       %count --; 
       %i--; 
   }


}

---------------------------------Server code: -----------------------------------------------

   for (%i = 0; %i < %count; %i++)
   {

                if( !%cl.isAIControlled() ){
                    commandToclient(%cl, 'CreateFlowers', %pos);
                    commandToclient(%cl, 'doReplicate');
                }
   }

That's cool Kefan I was planning on doing something similar, but not necessarily the dynamic creation like this.

Andrew Hull (Nov 02, 2006 at 20:52 GMT)

Hey, that's cool. How about a screen shot?

Kefan Xu (Nov 02, 2006 at 23:52 GMT)

Sure, i'll add some pictures.

Can we get a larger shot of that? lol

Look above pictures, the second picture shows flowers ( arrow pointed ) are created in game, here are
larger pictures ( 800x600):
