I am trying to change the physics object scale in the update loop. I create a Spatial and attached a RigidBodyControl to the spatial. I updated the Spatial scale but the physics doesn’t get updated
Thank in andvance.
[java] for (int i = 0; i < rootNode.getChildren().size(); i++) {
Spatial b = rootNode.getChild(i);
if(b.getName().equals(“Block”)){
b.setLocalScale(b.getLocalScale().x*1.01f);
}
}[/java]

You have to scale the collision shape…

I am using this:
b.getControl(RigidBodyControl.class).getCollisionShape().setScale();
However nothing is happening.
updated code:
[java]for (int i = 0; i < rootNode.getChildren().size(); i++) {
Spatial b = rootNode.getChild(i);
if(b.getName().equals("Block")){
b.setLocalScale(b.getLocalScale().x*1.01f);
b.getControl(RigidBodyControl.class).getCollisionShape().setScale(b.getLocalScale());
}
}[/java]
b.getControl(RigidBodyControl.class).setCollisionShape(b.getControl(RigidBodyControl.class).getCollisionShape().setScale(b.getLocalScale())) maybe?
Addez no it doesn’t work. I split up the command too.
[java] CollisionShape tmp = b.getControl(RigidBodyControl.class).getCollisionShape();
b.setScale(new Vector3f(5,5,5));
b.getControl(RigidBodyControl.class).setCollisionShape(tmp);[/java]
updated code:
[java]for (int i = 0; i < rootNode.getChildren().size(); i++) {
Spatial b = rootNode.getChild(i);
if(b.getName().equals(“Block”)){
b.setLocalScale(new Vector3f(10,10,10));
CollisionShape tmp = b.getControl(RigidBodyControl.class).getCollisionShape();
b.setScale(new Vector3f(10,10,10));
b.getControl(RigidBodyControl.class).setCollisionShape(tmp);
}
}[/java]
Try making a new collision shape, it will not yield a proper “physical” effect like blowing up a ballon or something anyway.

@funbox in that code above you are just getting the collisionshape and just setting it to itself. You don’t change it

Wezule it was a typo
