Tutorial 4 Working With Particles 209
Increasing the acceleration to that value slows the particles’ ascent, and also decreases
the maximum height they reach.
Simulations and Multiple Objects
The simulations used so far have been applied to, and have affected, a single object or
emitter. Some of the simulations work by interacting with multiple objects
simultaneously, such as Orbit Around. In this next section, add an object and the Orbit
Around behavior.
To add a shape to the project:
1 In the Library, select Shapes.
Drag the “5-sided star” from the stack to the Canvas.
2 In the Layers tab, double click 5-sided star 1, and type a new name: “Big Star.”
