An on/off switch using binary code. 1 = on, 0 = off.

You may want to design a variety of different drawings that will vary the appearance of your particle system. In this case, you should put each drawing on its own cell in the drawing layer. Each drawing will then be a new Type of particle.

Lets you choose sequentially assign a type (moving from one drawing to the next) or randomly.

This is the frame number where the first drawing can be found. If you have a 5-frame cycle that starts on frame 1, you would put a 1 here.

This is the frame number where the last drawing can be found. If you have a 5-frame cycle that starts on frame 1, you would put 5 here.

A different start frame number can be entered in this field. This means that a particle can start with a different drawing than the drawing on frame 1.

Allows a random deviation for the birth of the particles. If you have a five-frame cycle that starts on frame 1, but you want the particles to be a random type, then you may want to set the Age and Birth to 3 with a standard deviation of 2. That means the particles will randomly be born at any frame from 1 to 5.

Define a mass for the particles which will affect how the particles interact with gravity.

Lets you set how you would like the size of the particle to change as it ages. Attach a function to this attribute if you would like to, for example, have the particles get smaller as time goes on.

Scales the particle in the direction of its movement.

Set an exponent here for how much you would like that particle to scale.

Aligns the particle in the direction of its movement.

Select the axis that you want to align. This axis refers to the axis of the Drawing grid from the Drawing module plugged into the emitter.

You might want to have the particle align to the X direction of movement. You can see this property being used in the Lemmings example.

Similar to flipping the X axis, you may wish to flip the Y axis of a drawing to match the direction of the particle movement.

Enables rotation on the particle.

When you choose to do a Directional Scale, this will automatically maintain the volume of the particle by squashing it proportionally to how much it stretches as a result of the directional scale.

Colouring

Lets you choose how to define the colour of the particle.

In this case, the particle will remain the same colour as it was drawn with.

Attach a function to this to vary the Red, Green, and Blue values of the particle as it ages.

Attach a function to this to vary the Red, Green, Blue, and Alpha values of the particle as it ages.

Keep the original RGB values from the drawing, but vary the Alpha (Opacity) according to a function that you define here.

Change the Red, Green, and Blue values of the particles based on the frame. Changing based on the frame means that ALL particles will change colour on that frame, regardless of their age.

Change the Red, Green, Blue, and Alpha values of all particles on a given frame by attaching a function.

Use the original RGB values from your drawing, but vary the Alpha (Opacity) of the particles on a certain frame by attaching a function to this.

This is where you can attach functions to the Red, Blue, Green and Alpha values. You can also click on the colour swatch to adjust the colour.

Lets you attach a function to define how you want the particles to blur based on the age, frame or camera distance of each particle. There are low and high quality blurs. Also, you can attach a function to define how all particles should be blurred.

Lets you set a value or attach a function to animate the blur according to the type of blur that was defined from the drop-down list.

The distance where the blur fades from the edge of the image. Select a value between 0 and 1.

A falloff rate of 0 causes the blur to fade out slowly, distributing the blur evenly from the edge of the drawing to the farthest edge of the blur.

A falloff rate of 1 causes the blur to fade out quickly so that the blur is heaviest at the edge of the drawing.

Defines a blend mode for the particles to get cool effects.
