示例1: Update
public unsafe void Update(ParticleSystem particleSystem, float dt)
{
var lifetimeField = particleSystem.GetOrCreateField(LifetimeField);
// Iterate over particles
var particleEnumerator = particleSystem.GetEnumerator();
while (particleEnumerator.MoveNext())
{
var particle = particleEnumerator.Current;
var lifetime = (float*)particle[lifetimeField];
// Remove particle through enumerator.
// Enumerator will be valid again in next loop.
if ((*lifetime += dt) > Lifetime)
particleEnumerator.RemoveParticle();
}
}示例2: UpdateSectorLight
protected void UpdateSectorLight (ParticleSystem<Spark>.ParticleCollection particles, LightSource lightSource) {
int particleCount = 0;
int rAccumulator = 0, gAccumulator = 0, bAccumulator = 0, aAccumulator = 0;
Vector2 positionAccumulator = Vector2.Zero;

using (var e = particles.GetEnumerator())
while (e.GetNext(out particle)) {
particleCount += 1;

var particleColor = particle.GetColor();
rAccumulator += particleColor.R;
gAccumulator += particleColor.G;
