Switch from physical body to "static" collision

[eugene.litvinov]

I need realize some logic, when I can enable/disable physical body of object, so in one time it be physical, and in another - this is only static mesh with "static" collisions.

I use NodeReference node in game, get it physical body of it inner Node, and use Body::setEnabled(false); - but in this case node has no collision with any object or player, but if I remove Body from NodeReference in Editor mode, save it and load in game, then I will have "static" collision.

Question: how can I switch from body collision to "static" mesh collision and back for my NodeReference node?

Set zero mass for all shapes.

Set zero mass for all shapes.

Sorry, not understand, is next right?

NodeReference cube = new NodeReference("source/nodes/cube_blue.node");
cube.setPosition(pos);

Object innerObject = node_cast(cube.getNode());
BodyRigid body = innerObject.getBodyRigid();

for (int i = 0; i < body.getNumShapes(); i++)
{
Shape shape = body.getShape(0);
shape.setMass(0.0f);
}

body.setEnabled(false);

Cause it don't work :(

Have you tried it with body.setEnabled(true) ?

With body.setEnabled(true) it works. But I need disable Body, cause I need scale my object... I use unit scale, when I need to interact with physical object, and then in some moment I need to disable physical behavior, set different scale and leave object, but I need that another objects and player will collide with it. Then in some moment I need take this object, set unit scale and enable physical behavior.

Does sound a little bit complicated. As far as I know scaling for body shapes is not really supported. Anyway alternetivly you could provide 2 shapes (one unscaled and one scaled) and used appropriate Shape::setEnabled( true/false) calls based on game state.

I don't scale body shapes. I disable body, and scale object (mesh), when I enable body, it already the same, unit scale.

We can leave scale now, and it is all the same: when I disable physical body object not react like simple mesh with collision and intersection.
