Using the Particle Collision Event Editor, you can create, edit, and delete collision events for Maya classic particles and nParticles. The options in this editor let you specify the details of your particle collision event such as setting whether or not the source particle object dies and specifying number of new particles that are emitted from the event.
You can also create particle collision events using a MEL procedure. For information, see Create a MEL procedure for collision events.
Click a particle or nParticle object name in the Objects list to select it. All events belonging to the selected object are displayed in the Events window.
Specifies the details of the collision events such as the number and type of target particles created by the event.
Lets you specify the target particle object for the event. Type the name of the existing particle system you want to use as the target particle system. You can use either the name of the particle objects shape node (particleShape or nParticleShape) or its transform node name (particle or nParticle).
If you do not specify a particle type, the target will be an nParticle.
