[Solved] CharacterHitReport question

Hello,

I'm implementing a CharacterHitReport. If my character hits an item, the item shall change the colour. But how can I identify which item was hit.

I can check via the ActorGroup that is given by the onActor() funtion whether the hit actor is an item (as all items are in the same group), but how can I get now the item to call the cangeItemColour() function?

class CPlayerHitReporter : public NxOgre::CharacterHitReport
{
public:
NxOgre::CharacterHitReport::Response onActor(NxOgre::Character *, NxOgre::Actor *actor, NxOgre::Shape *, NxOgre::ActorGroup *actorGrp, const NxControllerShapeHit &)
{
if(actorGrp->getName() == "ItemGrp")
{
// Change colour here //
}
}

private:

};

PS: Sorry for the bad title, but I don't find a better one.

I've got it.

The onActor() function tells me the actor involved and I can retrieve its name und compare it with all the names of the items.

Usually, it's faster if you can compared pointers of the two classes. Assuming you have them handy.

So, you would advice my to get the NxOgre::Actor pointer of my CItem and comnpare it to the NxOgre::Actor pointer given by on Actor()?

If yes, how can I get the NxOgre::Actor of a NxOgre::Body (because that is what my CItem has)? I've only found a function to get the NxActor out of a NxOgre::Body.

Using your code, and "CItem" is cItem:

NxOgre::CharacterHitReport::Response onActor(NxOgre::Character *, NxOgre::Actor *actor, NxOgre::Shape *, NxOgre::ActorGroup *actorGrp, const NxControllerShapeHit &)
{
if(actor == cItem->mActor)
{
}
}


Huh? That does not function. My CItem class has no actor. There is only a NxOgre::Body. So where should this cItem->mActor come from?

Shall I take the NxActor?

Sorry, but I'm totally confused now.

Ignore the term NxActor; it doesn't apply it. With general usage of NxOgre; you never met the class. So forget the term.

Right, back to topic. The NxOgre::Body is a NxOgre::Actor too. But not the other way around. Just think of a NxOgre::Body as a Actor with some code to tell Ogre to render itself on the screen.

Now; You can still compare the pointers because they are both actors.

if (actor == citem->mBody) {
// do code.
}

I knew that, however I did not know that this will function

Thanks. It works now!!!
