Hi,
the id is not the object id but the collision id,
you can get it using "entity->getPhysicsProperties();" (it is NULL if the object doesn't have physics enabled)

MPhysicsProperties * phyProps = ent->getPhysicsProperties();
if(phyProps)
nbColl = physCont->isObjectInCollision(phyProps->getCollisionObjectId());

Hi, i try to count the number of meshs which are in collision with an ghost entity, but maratis crash ... this is the code I use :

MEngine * engine = MEngine::getInstance();
MyGame * game = (MyGame*) engine->getGame();
MLevel* lvl = engine->getLevel();
MScene* scene = lvl->getCurrentScene();
unsigned int Id;
int nbColl;
MOEntity* ent= scene->getEntityByName("myEntity");
scene->getObjectIndex(ent->getName(), &Id);
MPhysicsContext * physCont = engine->getPhysicsContext();
nbColl = physCont->isObjectInCollision (Id);
// here maratis crash
