Falloffs can be used to isolate the strength of most Behaviours. By default, a Falloff outputs a value of 1 at its center which falls off to 0 at its edges. This value is used as a multiplier for the Strength of the Behaviour(s) it is connected to and the Graph can be used to determine the speed the values fall off at.
Strength - a multiplier for the Falloff Graph attribute.
Circle - the Falloff Graph is sampled radially.
Rectangle - the Falloff Graph is sampled in x and y.
Linear - the Falloff Graph is sampled in 1 dimension.
Size - set the size of the Falloff.
Falloff Graph - see Graph Attribute.
Probability - the Falloff's value is used to produce a 1 or 0 (true or false) value. For example, a Falloff value of 0.5 would give you a 50% chance of getting a 1.
Seed - changing this value will affect Probability.
Custom Color - when checked the Falloff will use the value set in Color. When unchecked the Label Color is used (the color used in the Scene Window).
Color - set a color for the Falloff.
Enabled - when unchecked, the Falloff will output a value of 1 (the result being the same as if the Falloff wasn't there).
