ADOBE DIRECTOR BASICS
3D: Controlling appearance
2 In the Message window, execute the following command:
new(#script).scriptText = Particle_GetScriptText(member("3D"), "Particle Test")
This will create a new Movie Script member in your movie.
3 Stop the movie and restart it. All the changes that you made to the Particle system will be lost.
4 In the Message window, execute the commands below:
vList = Particle_GetPropertyList() -- in your new
scriptParticle_SetProperties(member("3D"),"Particle Test",vList)
Initially, the new script will be created as a Movie Script. If you call Particle_GetPropertyList(), only the first movie
script with that handler will respond. If you want to create a number of different Particle systems, you can give the
scripts different names. The following are some commands to test in the Message window.
v3DMember = member("3D")
vName = "Explosion"
vPropList = script(vName).Particle_GetPropertyList()
vResource = Particle_SetProperties(v3DMember, vName, vPropList)
vModel = v3DMember.newModel(vName, vResource)
Using textured particles
These commands create a new particle modelResource, and a new model, using the data stored in the Explosion
script.
In the Snow example in the Particles.dir movie, the snowflakes display a texture. Each particle is in fact a square plane.
If you set the texture property of a #particle modelResource, that texture will be applied to the square plane. You can
use a 32-bit image with transparency in the alpha to hide parts of the square. Since the snowflakes are round, a square
texture mapped to a square plane works perfectly.
You can change the texture of a #particle modelResource on the fly. Immediately, all the particles will change their
texture. To see this in action, show the Snow particles in the Particles.dir movie, then click on the 3D sprite. You will
see the snowflakes spin. To see another example of textured particles, download and launch the movie Balloons.dir.
The balloon particles do not appear to be square, because of the alpha-channel transparency in the texture.
In this movie, too, the texture is mapped to a square plane. However, only a narrow part of the texture is opaque, so
the balloon particles appear to be tall and thin. See “Images for textures” on page 144 for more details.
