HPL3/Particles/Emitter Management

Emitter management controls

These controls help to add, duplicate and remove particle emitters. The Add button will create a new particle emitter and select it (i.e. pick it in the combo box), the Copy button will create a copy emitter out of the selected one, and the Delete button will delete the selected emitter.

When a particle emitter is selected, all its parameters will be shown in the tab frame below.

General

• Name: The name of the emitter currently selected.
• Max Particles: The maximum number of particles that can be alive at once. When this limit is reached no more particles will be created.
• Particles per Second: The number of particles per second that will be created.
• Start time offset: Time offset in seconds before the emitter starts.
• Respawn dead particles: If dead particles should be respawned.
• Warm up time: Time that the emitter gets to warm up. This is useful when doing a a stream of something (like a fire or waterfall) and the particles should not be shown “starting up”.
• Pause: A pause is a break during which no particles are created. Particles are updated though.
• Pause Length: The length of the pauses, 0 and 0 means that there are no pauses.
• Pause Interval: The length between pauses. 0 and 0 means that there are no pauses.
• Offset position: How the emitter is offset relative to its starting position.
• Offset angle: How the particle system is offset relative to its start angles.
