I don't want to post the whole file because I really haven't changed
anything else and that would be massive, so here's the tidbit i'm
working with. The whole file is c_effects.cpp if you need to see the
rest.
inline bool CClient_Precipitation::SimulateRain(
CPrecipitationParticle* pParticle, float dt )
{
if (GetRemainingLifetime( pParticle ) < 0.0f)
return false;
Vector vOldPos = pParticle->m_Pos;
// Update position
VectorMA( pParticle->m_Pos, dt, pParticle->m_Velocity,
pParticle->m_Pos );
// wind blows rain around
for ( int i = 0 ; i < 2 ; i++ )
{
if ( pParticle->m_Velocity[i] < s_WindVector[i] )
{
pParticle->m_Velocity[i] += ( 5 / pParticle->m_Mass );
// clamp
if ( pParticle->m_Velocity[i] > s_WindVector[i] )
pParticle->m_Velocity[i] = s_WindVector[i];
}
else if (pParticle->m_Velocity[i] > s_WindVector[i] )
{
pParticle->m_Velocity[i] -= ( 5 / pParticle->m_Mass );
// clamp.
if ( pParticle->m_Velocity[i] < s_WindVector[i] )
pParticle->m_Velocity[i] = s_WindVector[i];
}
}
// No longer in the air? punt.
if ( !IsInAir( pParticle->m_Pos ) )
{
// Possibly make a splash if we hit a water surface and it's in
front of the view.
if ( m_Splashes.Count() < 99 )
{
if ( RandomInt( 0, 100 ) <
r_RainSplashPercentage.GetInt() )
{
trace_t trace;
UTIL_TraceLine(vOldPos, pParticle->m_Pos, MASK_ALL, NULL,
COLLISION_GROUP_NONE, &trace);
if( trace.fraction < 1 || trace.DidHit() )
{
if ( RandomInt( 0, 100 ) <= r_RainSplashPercentage.GetInt() )
DispatchParticleEffect( "rain_splash", trace.endpos,
trace.m_pEnt->GetAbsAngles() , NULL );
}
}
}
// Tell the framework it's time to remove the particle from the
list
return false;
}
// We still want this particle
return true;
}
