示例1: adjustVelocityForRectangleCollision
private void adjustVelocityForRectangleCollision(Entity entity, float deltaT, Rectangle rect, ref Vector2 velocity)
{
Vector2 intersectionAmount;
Vector2 tempPosition = entity.Position + (velocity * deltaT);
if (rect.EIntersects(entity.GetBoundingBoxAt(tempPosition)))
{
tempPosition = entity.Position;
tempPosition.X += velocity.X * deltaT;
if (entity.GetBoundingBoxAt(tempPosition).Intersects(rect, out intersectionAmount))
{
bool positive = velocity.X >= 0;
velocity.X -= intersectionAmount.X / deltaT;
if ((positive && velocity.X < 0) || (!positive && velocity.X > 0))
velocity.X = 0;
}
tempPosition = entity.Position;
tempPosition.Y += velocity.Y * deltaT;
if (entity.GetBoundingBoxAt(tempPosition).Intersects(rect, out intersectionAmount))
