Summary

    This chapter provided several recipes for the Linden Scripting Language particle emitter system. The particle emitter allows a prim to emit 2d particles. These particles can be used to create many different effects. This chapter provided recipes that demonstrate some of the most common uses for particle scripts.

    A basic particle emitter script was presented that establishes all of the parameters necessary to begin emitting particles. Unmodified, the basic particle emitter script emits red particles upwards. However, the basic particle emitter script is meant to be a starting point for other particle emitter scripts. Many of the recipes in this chapter started with the basic particle emitter script.

    Particle emitter scripts can be very useful for creating smoke. A recipe to create a chimney was presented in this chapter. The chimney script extended the basic particle script to produce puffs of smoke. When combined with a brick textured object, a chimney is produced.

    Trees are very common in Second Life. An interesting fall effect can be created by causing leaves to fall from trees. A recipe is provided that creates a particle emitter that emits leafs. The leaves float gently in the wind.

    Jewelry is another common user of particle scripts in Second Life. By using a particle script, Jewelry can be made to glitter. This effect is often called bling. Such “bling enabled” jewelry has become very popular in Second Life.

    Particle emitter scripts can also be useful for causing vehicles to produce trails. The next chapter introduces Second Life vehicles. One of the vehicles will use a particle emitter script to leave waves behind a boat as it travels in the water.
