I was reading couple of tutorials regarding steering behaviour and there is one thing that confuses me.
To calculate position for my agent i need to sum up all steer forces and accumulate into velocity:
steerForce = calculateSteeringForces();
steerForce.truncate(maxForce);
velocity += steerForce;
velocity.truncate(maxSpeed);
position += velocity;I will take seek behaviour for example:
desiredVel = normalize(target - agent.position) * maxVel;
return desiredVel - agent.velocity;and at some point i need to stop my agent from moving, should i check magnitude of steerForce like:
steerForce = calculateSteeringForces();
if(steerForce.length() < epsilon)
return; //stop
steerForce.truncate(maxForce);
velocity += steerForce;
velocity.truncate(maxSpeed);
position += velocity;because velocity is always > 0.
