示例1: Update
public void Update(IRenderer renderer, double time)
{
using (var g = renderer.AcquireAuto())
{
// When the user moves the window we make the particles react to
// this movement. The reaction is semi-random and not physically
// correct. It looks quite good, however.
if (position_changed)
{
for (int i = 0; i < Particles.Count; i++)
{
Particle p = Particles[i];
p.Velocity += new Vector2(
16 * (position_dx + 0.05f * (float)(rand.NextDouble() - 0.5)),
32 * (position_dy + 0.05f * (float)(rand.NextDouble() - 0.5)));
Particles[i] = p;
}
position_changed = false;
}
}
// For simplicity, we use simple Euler integration to simulate particle movement.
// This is not accurate, especially under varying timesteps (as is the case here).
// A better solution would have been time-corrected Verlet integration, as
// described here:
// http://www.gamedev.net/reference/programming/features/verlet/
