Hi,
Here's the second problem I have found:
-----------------------------------------------
2. Now I have various objects created from a PROTO and I would like to
eliminate them from the wrl by clicking on them. How can I know which is which?
The following example is another frustrated effort:
PROTO fooProto [
field SFVec3f position 0 0 0
field SFNode father NULL ]
{
# Define Shape of object and the TouchSensor which has to activate deletion
DEF GenTrans Transform {
translation IS position
children [
Shape {
geometry Box { size 1 1 1 }
appearance Appearance { material Material { diffuseColor 1 1 1 } }
}
DEF TSProtoD TouchSensor {}
]
}
# Script which deletes object
DEF DelProto Script {
directOutput TRUE
eventIn SFBool delete
field SFNode whoami NULL
field SFNode environment IS father
url "vrmlscript:
// Hold identity in field "whoami"
function initialize(){
whoami = environment.children_changed[
environment.children_changed.length - 1];
}
// Delete object whose pointer is held in "whoami"
function delete(v) {
if(v){
environment.removeChildren = new MFNode(whoami);
}
}
"
}
ROUTE TSProtoD.isActive TO DelProto.delete
}
DEF Environment Group {
children [
fooProto{ position 5 0 0, father USE Environment }
fooProto{ position 0 0 0, father USE Environment }
fooProto{ position -5 0 0, father USE Environment }
]
}
When I click on any of the cubes, nothing happens!
If I change the line in the "initialize" function for:
whoami = environment.children_changed[0];
then, when I click on any of the objects, the first cube is deleted but the
rest (of course) are not.
* Anybody has a clue why this happens?
* Anybody has alternatives to doing this?
---------------------------------------------
Thank you very much in advance!
Best regards,
Narcis.
