[SOLVED]Low-level collision problems

F1rst

15-07-2006 17:57:47

Hello!
I'm trying to use OgreNewt for low-level collision detection.
If I use box vs. box(or other simple primitives)
my program crashes, if I use mesh vs. mesh I ALWAYS
get 0 contact points even if they collide.
Where am I wrong,answer please?
Here is my code:

#include "ExampleApplication.h"
#include "OgreNewt.h"

OgreNewt::Collision *Ogrecol,*Robotcol;

class TutorialFrameListener : public ExampleFrameListener
{
public:
TutorialFrameListener( RenderWindow* win, Camera* cam, SceneManager *sceneMgr ,OgreNewt::World* W)
: ExampleFrameListener(win, cam, false, false)
{
mWorld=W;
mSceneMgr=sceneMgr;
Ogrenode=mSceneMgr->getSceneNode("Ogrenode");
Robotnode=mSceneMgr->getSceneNode("Robotnode");
Camnode=mSceneMgr->getSceneNode("Camnode");
CamRnode=mSceneMgr->getSceneNode("CamRnode");
mCamera=cam;

mRotate=0.13;
LogManager::getSingleton().logMessage("#TutFrameconstructor#");
}

bool frameStarted(const FrameEvent &evt)
{
tv=Vector3::ZERO;
cv=Vector3::ZERO;
mInputDevice->capture();
if (mInputDevice->isKeyDown(KC_W))
tv.z+=-1;

You create the collisions:
Ogrecol=new OgreNewt::CollisionPrimitives::Box( mWorld,Vector3(100,100,100));
Robotcol=new OgreNewt::CollisionPrimitives::Box( mWorld,Vector3(50,50,50));

But not the bodies. Try adding this after it:
OgreNewt::Body* Ogrebody = new OgreNewt::Body(mWorld, Ogrecol);
OgreNewt::Body* Robotbody = new OgreNewt::Body(mWorld, Robotcol);

Now your objects are movable if you add:

Robotbody->attachToNode(Robotnode);


You'll want to try moving them from the origin to test collision, unless you have something to drop them on.

I don't need to use a bodyes(a real simulations) because I need
LOW LEVEL collision detection.
I read about OgreNewt::CollisionTools::CollisionCollide in OgreNewt
docs- this function don't need any "bodyes" we can just manually
set position and orientation of our nodes

int OgreNewt::CollisionTools::CollisionCollide ( const OgreNewt::World * world,
int maxSize,
const OgreNewt::Collision * colA,
const Ogre::Quaternion & colOrientA,
const Ogre::Vector3 & colPosA,
const OgreNewt::Collision * colB,
const Ogre::Quaternion & colOrientB,
const Ogre::Vector3 & colPosB,
Ogre::Vector3 * retContactPts,
Ogre::Vector3 * retNormals,
Ogre::Real * retPenetrations
)

manual collision between collision primitives.

This function allows you to perform a manual collision check on 2 collision primitives. the function returns the number of contacts found.

Oh jeez, sorry - thought you were testing collision abilities first - I completely passed over the line /* Here is crash */ because I thought the whole section was commented out! The forum totally train-wrecked the formatting there hehe...

Perhaps try creating the collisions locally where you test them. I've never used the low-level collision testing, but I'd still imagine you'd need to create a body to move the collision around. I'll have to re-read the docs about that, never messed with it before.

No, unfortunately, it doesn't work. :cry:

Say to me please how to use CollisionCollide function and
where is my mistake.Thanks..

i haven't tested them to be honest! has any other user used these functions?

they are pretty much direct wraps of Newton functions...

I'll probably be using the low-level colisions soon, I'll let you know how it goes. :)

Ok, thanks.
If someone wants to test CollisionTools functions, you can just
insert my source code given above in empty ogrenewt project and compile
it.

Good news!
It was my fault, because I use poiter Vector3 * retc instead of
array Vector3 rect - that's why my program crashes.
Box vs Box collide perfectly.
But I still have another question(Problem mesh vs Mesh) - I will add it in new topic.
