Repelling and attracting particles (PB only)


    Use Repel to control how nearby particles repel or attract each other. This feature simulates adding a positive or negative magnetic charge to each particle. You can specify which particles, layers, or characters are the repelling force and which are repelled.

    Note: If you want to repel an entire layer of particles away from a specific area, use Wall (see Containing particles with a wall (PB only)) or Gradient Force in Property Mappers (see About Property Mappers (PB only)).

    You can adjust the following options for Repel:

    Force

    Specifies the repel force. Greater values repel particles with more force; negative values result in particle attraction.

    Force Radius

    Specifies the radius (measured in pixels) within which particles are repelled. Another particle must be within this radius to be repelled.

    Repeller

    Specifies which particles act as the repellers or attractors to another subset you specify using the Affects option. See Using Affects options to specify particles (PB only).

    Affects

    Specifies a subset of the layer's particles to which repulsion or attraction applies. See Using Affects options to specify particles (PB only).
