使用纹理发射nParticle

nParticleShape1.goalV +=.01;

 

nParticleShape1.goalV +=.01*-1;

 

 

goalV

 

if(nParticleShape1.goalV <=.045)

{

nParticleShape1.lifespanPP = -1;

nParticleShape1.goalU +=noise(sphrand(time+nParticleShape1.particleId));

 

 

nParticleShape1.goalU +=noise(sphrand(time+nParticleShape1.particleId))*.0015;

 

 

nParticleShape1.goalU +=(noise(sphrand(time+nParticleShape1.particleId))*2.5)*.0025;

 

 

nParticleShape1.goalU +=(noise(sphrand(time+nParticleShape1.particleId))*2.5)*.0015;

 

噪声和Abs函数调整粒子行为

nParticleShape1.goalV +=abs(noise(sphrand(time+id)));

nParticleShape1.goalV +=(noise(sphrand(time+nParticleShape1.particleId)))*.10;

 

nParticleShape1.goalV +=abs((noise(sphrand(time+nParticleShape1.particleId)))*.10);

 

 

nParticleShape1.goalV +=abs((noise(sphrand(time+nParticleShape1.particleId)))*.10)*-1;

 

 

nParticleShape1.goalV +=abs((noise(sphrand(time+nParticleShape1.particleId)))*.050)*-1;
