Hello,
I tried to add the interface for convexSweepTest in awayphysics.swc
but it seems not work. It’s time-consuming and get the wrong result.
source as below(awayPhysics.c)
==================================================
AS3_Val sweptSphereTest(void* data, AS3_Val args){
btCollisionObject* obj;
double fromx, fromy, fromz;
double tox, toy, toz;
double radius;
AS3_ArrayValue(args, "PtrType,DoubleType,DoubleType,DoubleType,DoubleType,DoubleType,DoubleType,DoubleType", &obj;, &fromx;, &fromy;, &fromz;, &tox;, &toy;, &toz;, &radius;);
if(collisionWorld)
{
btSphereShape* sweptShape = new btSphereShape(radius);
btVector3 source(fromx, fromy, fromz);
btVector3 dest(tox, toy, toz);
btCollisionWorld::ClosestConvexResultCallback cb(source, dest);
btTransform from;
from.setIdentity();
from.setOrigin(source);
btTransform to;
to.setIdentity();
from.setOrigin(dest);
btVector3 hit_surface;
btVector3 hit_com;
btVector3 normal;
double hit_fraction;
collisionWorld->convexSweepTest (sweptShape, from, to, cb);
if (cb.hasHit ())
{
hit_surface = cb.m_hitPointWorld;
hit_com.setInterpolate3(source, dest, cb.m_closestHitFraction);
hit_fraction = cb.m_closestHitFraction;
normal = cb.m_hitNormalWorld;
normal.normalize ();
//get rigid body from collision object
btRigidBody* body = btRigidBody::upcast(cb.m_hitCollisionObject);
//clone result
SphereSweptInfo out(hit_surface, hit_com, normal, hit_fraction, body);
return_as3_ptr(&out;);
} else {
hit_com = dest;
hit_surface = dest;
hit_fraction = 1.0f;
normal = btVector3(1.0, 0.0, 0.0);
return AS3_Null();
}
}
return AS3_Null();
}
==================================================
I have check the out struct(SphereSweptInfo) in as3 source pointer.
Is it wrong?
