Hi everyone,

I need to manipulate the keyValue inside PositionInterpolator. That means keyValue can be
[x1 y1 z1,
x2 y2 z2]

x, y, z are based on calculation from user's input. I have a script to compute x,y,z but the problem is keyValue is an exposedField and I cannot ROUTE my result to keyValue. Only eventIn can be routed to eventOut. I tried doing this:

PROTO CalculatePos [
eventIn SFFloat x_pos # this is from user
field MFVec3f keyValue []
# this is the PositionInterpolator I defined outside of this
#PROTO
field SFNode PosInt USE POSINT
] {
DEF CalPos Script {
eventIn SFFloat x_pos IS x_pos

url "vrmlscript:
function x_pos (){
<compute x,y,z for keyvalue>
PosInt {keyValue[]};
}"
}
}

I got a complain in PosInt {keyValue[]}; when I tried executing. Any idea from you guys or is there a better way to do so? Would like to hear from you.

This line is syntactically not correct.
It must look like:

PosInt.keyValue= ...;

The whole function should look like this:

function x_pos(val)
{
var ani= new MFVec3f;
<compute the values>
PosInt.keyValue= ani;
}
