adding a collision modifier to a created group

[Chanizz]

ok, got this group,:
ufoGroup = pWorld.newGroup("planegroup")

and then i wanna add a collision to it like :

ufogroup.addmodifier(#collision)
ufogroup.collision.mode = #mesh
ufogroup.collision.resolve = TRUE

it doesnt work, how come?

[openspark]

The Collision Modifier needs to be attached to models, not groups. A group does not have any geometry as such, and the Collision Modifier needs geometry in order to work.

ok, damn!
but can u put a modelsunderray on it?

[openspark]

No. ModelsUnderRay() will detect models, not groups, for the very same reason:
collisions imply geometry.

What exactly are you trying to do? It sounds as if you should:

* Detecting collisions with the models that belong to the group
* Determine which group the model belongs to
* Control the collision at the group level

well i have a flightsim with a really cool stearing system that looks soo nice.
Allt he stearing is made with a group that has the actual model as a child. if
i put a collision on the model, the group will just go ahead without the model
if there is any collision.

[openspark]

Would it help to make the parent of the actual model an invisible model,
possibly with simplified geometry? This would allow you to perform collision
detection on the invisible model, while leaving the actual model with its
current relationship to a parent.
