particleFloat Sample Script

Description:

The following script sets each particle's float value as one tenth of its particle ID, or birth index number.

Can Be Used With:

Can be used to control the .Force value of Force and Speed_Keep_Apart Operators.

Force : Helper

Speed_Keep_Apart : Helper

Effect:

The first particles get a low float value, and thus a low Influence value, and each successive particle gets a larger float value than the one before. As a result, the later a particle is born, the more subject it is to the space warp(s) in the operator.

Example:

--The ChannelsUsed handler defines the channels

--to be made available to the script.

--For the list of all channels, see

--Interface: MaxscriptParticleContainer

--The parameter pCont passed to the handler

--contains the Particle Container the script is applied to

on ChannelsUsed pCont do

(

pCont.useFloat = true --enable the Float channel

)

 

--The Init hander is called on initialization.

--It is not used in this case.

on Init pCont do

(

)

 

--The Proceed handler contains the main script

--applied to the Particles.

--The parameter pCont passed to the handler

--contains the Particle Container the script is applied to:

on Proceed pCont do

(

--Get the number of particles

count = pCont.NumParticles()

 

--Loop from 1 to the number of particles:

for i in 1 to count do

(

 

--Set the particle index in the container to the current i value.

--This makes the i-th particle in the container the current one

pCont.particleIndex = i

 

--Set the particleFloat channel value of the current particle

--to the particleID of the current particle divided by 10.0.

--The younger the particle, the higher the particleFloat value.

pCont.particleFloat = pCont.particleID/10.0

)--end i loop

)--end Proceed

 

--The Release handler is used to do cleanup work.

--Not used in this case.

on Release pCont do

(

)
