Creator

The Creator object is a level object that generates duplicate copies of its sub-objects during an animation. The level that contains the Creator must have the Simulation property turned on. There are many uses for creator objects: bullets being shot from a gun, bees leaving a hive, water dripping from a faucet, just to offer a few examples. Creator objects can be animated using keyframes or paths, just like many other object types.

The Active checkbox turns creation on and off. You can animate it to achieve object creation at suitable intervals.

A creator objects moves along a path and shoots spheres around

The Parent Level attribute specifies how many hierarchy levels above the creator the emitted objects are inserted. The default is 0, which causes objects to be inserted at the same hierarchy level that contains the Creator object.

The Creation Interval attribute defines the time interval between the creation of emitted objects; that is, it defines how rapidly the Creator emits objects. The smaller the value, the more objects are created. The time interval is specified in the current time units (defined through the Options window). So, for instance, if your time units are frames, setting the creation speed to 15 will cause a sphere to be emitted every 15 frames, or two times per second for an NTSC video system. If the Channel gadget below the creation interval gadget includes a channel selection, materials that affect the creator are evaluated at each sample object position. The evaluated channel value is multiplied with the creation interval value. The result is used as the actual sample specific creation interval.

The Life Time attribute defines the time interval that an emitted object is active before being destroyed (i.e. its lifespan). The smaller the value, the shorter the object's life. The time interval is specified in the current time units (defined through the Options window). So, for instance, if your time units are frames, setting the Life Time to 15 means a sphere is active for 15 frames (0.5 seconds in NTSC video) before being destroyed. If the Channel gadget below the life time interval gadget includes a channel selection, materials that affect the creator are evaluated at each sample object position. The evaluated channel value is multiplied with the life time value. The result is used as the actual sample specific life time.

The Velocity attribute defines the rate at which the created objects move, in meters per second. Since this attribute is a vector value, you define velocities along the three axes. To get motion only along the X axis, you would enter a value such as "0.5 0 0". Velocity is defined in the Creator object's space. The Channel gadget defines a material channel whose contents is multiplied with the given velocity value to obtain the sample object specific velocity.

The Spin attribute defines the rate at which an emitted object spins. Since this attribute is a vector value, you define the spin along the three axes. If the associated Channel gadget includes a channel selection, materials that affect the creator are evaluated at each sample object position. The evaluated channel value is multiplied with the spin value. The result is used as the actual sample specific spin.
