Falloff

Intro​

Falloffs can be used to isolate the strength of most Behaviours and Fields. By default, a Falloff outputs a value of 1 at its centre 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.

Common Attributes +

Strength - A multiplier for the Falloff Graph attribute.

Shape Type:

  • 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.
  • Sweep - The Falloff Graph is sampled in a similar way to a sweep gradient. Use the Falloff's Rotation to create radar like effects.
  • Shape - The Falloff Graph is sampled using a custom Shape(s).

Size - When the Shape Type is set to Circle, Rectangle or Linear, set the size of the Falloff.

Repetitions - When the Shape Type is set to Sweep, set the number of times the sweep is repeated within the Angles.

Angles - When the Shape Type is set to Sweep, set a start and end angle for the Falloff.

Input Shapes - When the Shape Type is set to Shape, connect the Shapes to be used as the Falloff.

Path Mode - When the Shape Type is set to Shape, determine how the Shape is

  • Filled Path - Any 'point' within the Input Shapes' is considered to be at full strength.
  • Path Edges - The distance from the Input Shapes' edge is used to calculate the Falloff's strength.

Distance - When the Shape Type is set to Shape, set distance from the Input Shapes that the Falloff Graph is sampled across. A distance of 0 means only the points inside the Shapes will be considered 'on'.

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).

info

A Falloff can also be Enabled/Disabled in the Scene Window by selecting it and choosing Enable/Disable Falloff(s) in the right click contextual menu.
