Inheritance

Members

TP_MasterSystem. AllocParticle ( )

Allocates a particle.

Return type: int
Returns: The particle ID of the allocated particle, or NOTOK if the allocation failed.
TP_MasterSystem. AllocParticles ( num )

Allocates num particles and stores their particles IDs.

Note

The count of allocated particles might be unequal to num due to the limit in the settings Max Particles . Change it to increase the count of allocatable particles.

Return type: list of int
Returns: The list with the allocated particle IDs.
TP_MasterSystem. FreeParticle ( pid )

Note

Normally this should not be used. Instead you should use SetLife() with a negative time, so that the particle in question dies immediately.
