It also doesn't help that you're only doing the trace when the random value
is within the current limit.
You need to do the check ALL the time, regardless of if it will actually
spawn it or not.
Displacements are a single plane, chances are you're repeatedly skipping the
actual check 99% of the time.
Your original code was correct except for the order. ie: new code:
trace_t trace;
UTIL_TraceLine(vOldPos, pParticle->m_Pos, MASK_ALL, NULL,
COLLISION_GROUP_NPC, &trace);
if( trace.fraction < 1 || trace.DidHit() )
{
if ( RandomInt( 0, 100 ) <= r_RainSplashPercentage.GetInt() )
DispatchParticleEffect( "spash", trace.endpos,
trace.m_pEnt->GetAbsAngles() , NULL );
}
Also, you can verify it if you set r_RainSplashPercentage to 101 (because
even if you set it to 100, it would never trace as it would HAVE to be below
the value.)
