Title:
Delta V motion not applied properly
Status in The New Real Time Battle Project:
Fix Committed
Status in New Real Time Battle alpha series:
Fix Committed
Bug description:
In cpp/sim_engine/base_object/base_object.cpp we are not applying
motion properly, only half the deltaV should applied to motion, rather
than the entire deltaV. In other words:
velocity = oldV + (accel*Time);
applyV = oldV + ((accel*Time)/2);
location += applyV * time
rotation should be handled in similar manner. Following is the method
where the fault lies:
bool base_object::apply(int time, float quanta)
{
// move acording to forces
float tmass = mass + mass_mod;
triplet a = force / tmass;
triplet ra = torque / (tmass * 0.5); // not accurate!!
velocity += (a + accel_mod) * quanta;
rotation += (ra + torque_mod) * quanta;
location += velocity * quanta;
attitude += rotation * quanta;
// apply post-effectors
bool killme (false);
for (auto e : post_attribs)
if (e.second->tick(*this, time))
killme = true;
return killme;
};
