Well the code is mostly fixed.
bool Collide(RigidBody* other, Vector4f& collision)

int which = -1;
axies.resize(0);
minmax.resize(0);
Vector3f offset = pos - other->pos;
for (count = 0; count < GetFaceSize(); count++)
{

Project(dir, min0, max0);
other->Project(dir, min1, max1);
if (max0 < min1 || max1 < min0)
return false;
axies.push_back(dir);

}
for (count = 0; count < other->GetFaceSize(); count++)
{

}
int counts;
for (count = 0; count < GetFaceSize(); count++)
{
for (counts = 0; counts < other->GetFaceSize(); counts++)
{
dir = GetNormal(count).CrossProduct(other->GetNormal(counts));

}
}

{

}
collision = Vector4f(axis, dist);
return true;
}
The cross product of the 2 box faces is for edge testing. And the check for a 0 direction is because cross product of same directions give you a 0.
Ty snake5 on the min/max, that was a problem, and the "touching == true" was unneccessary.
It works mostly. When two oobs meet, I seem to get caught or pushed out of the hallway.
