Flexscript question (network nodes and splines)

I attached a very basic model with two network nodes and a path linking them. I know how to curve this path manually but I want to do this in Flexscript to do it dynamically in a larger project.

Does anyone know a series of commands that will accomplish what I want?

Thanks in advance.

I don´t got any idea if there exists such commands. But if you don´t find any other solution you could have a look into tree and see what hapens while you set your options manualy. Then you only have to work with standard tree settings and commands.

Here's some code for creating a single spline point, which might be easier to manage than two. The coordinates are relative to the network node that contains the spline end points that were created when you connected the two nodes, and is the node you dragged from.

treenode networknode=node("/NN1",model());    // This is the network node you did a drag connect FROM
treenode splineend1 =first(networknode);    
double x=1;
double y=1;
double z=0;
if(nrop(outobject(splineend1, 1)) == 0)
{
	treenode splineend2=outobject(splineend1, 1);
	clearcontents(connectionsout(splineend1));
	treenode splinepoint=createinstance(node("/SplinePoint",library), up(splineend1));
	setloc(splinepoint,x,y,z);
	objectconnect(splineend1, splinepoint);
	objectconnect(splinepoint, splineend2);
}
set(node("/DefaultNetworkNavigator>variables/modified",model()), 1);

To expand on this solution, I've created a user function that does this for any two network nodes.

modifyspline(treenode from, int fromPort)

treenode net1=parnode(1);
int net1Port = parval(2);
treenode splineend1 =node(concat("/", numtostring(net1Port)), net1);
double x = 1;
double y = 1;
double z = 0;
treenode splineend2=outobject(splineend1, 1);
clearcontents(connectionsout(splineend1));
treenode splinepoint=createinstance(node("/SplinePoint",library), up(splineend1));
setloc(splinepoint,x,y,z);
objectconnect(splineend1, splinepoint);
objectconnect(splinepoint, splineend2);
set(node("/DefaultNetworkNavigator>variables/modified",model()), 1);

The x/y/z values should be changed according to your needs.

Note: "from" should be the node in which the spline object data resides (the node of origin when doing the "A" connection).

Hi,

i'm using the examples of this post to generate splines to caracterize curves when generating paths... but now it's not working on version 7.

i get the error:

exception: Exception caught in flexscript execution of line 6 instruction 18. Discontinuing execution.

not sure how to fx this... any help is welcome...

regards

Pablo

In version 7 the splines have moved to the connectionsout node inside the network node, so the previous code won't work. Try this:

treenode nn=so();
int edgeno=1;
treenode edge=rank(connectionsout(nn),edgeno);
function_s(nn,"setEdgeGeomType",edge,0);
treenode splines=node("/spline",rank(connectionsout(nn),edgeno));
treenode spline1=rank(splines,2);
treenode spline2=rank(splines,3);
setloc(spline1,x1,y1,z1);
setloc(spline2,x2,y2,z2);
