示例1: limitVelocity
float limitVelocity(Body hull, float max)
{
Vec2 velocity = hull.GetLinearVelocityFromLocalPoint(Box2DX.Common.Vec2.Zero);
var vec1 = hull.GetXForm().R.Col2;
var projection = Vec2.Dot(velocity, vec1);
vec1 *= projection;
var A = vec1.Length();
if (A > max)
{
var k = max / A;
hull.SetLinearVelocity(vec1 * k);
}
return A;
}
示例2: killWheelOrthogonalVelocity
void killWheelOrthogonalVelocity(Body hull, Body wheel)
{
var p_hull = hull.GetPosition();
var p_wheel = wheel.GetPosition();
var velocity = wheel.GetLinearVelocityFromLocalPoint(Vec2.Zero);
var vec1 = wheel.GetXForm().R.Col1;
var projection = Vec2.Dot(velocity, vec1);
vec1 *= projection;
var k = vec1.Length() / 0.001f; // превышение боковой скорости 1 мм / с
if (k < 0.1f) k = 0.1f; if (k > 10f) k = 10f;
float force = -k * 3000; //warning - mn
vec1.Normalize();
hull.ApplyForce(force * vec1, p_wheel);
