particleInteger Sample Script

--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.useTime = true
--Enable the Speed channel:

--Enable the Integer channel:
pCont.useInteger = true

--It is not used in this case.

--speed against the fastSpeed value. If faster, assign 2, if slower,
