This daemon creates a force field along a customizable path. The path can be created in RealFlow's viewport directly, imported as a SVG, or copied from an already existing → spline node. The spline's viewport representation is controlled with the → “Display Spline” panel. We also recommend enabling the → “Display Force Field” option for a realtime view of the daemon's forces.
Affect
With “Force” it takes a little time to display the daemon's full influence and the result is a curved stream of particles. “Velocity” directly affects the particles from the very beginning without any delay or acceleration, and you will get a linear particle stream. “Velocity” is not available for rigid/soft bodies.

A click on this button enables the “Edit” mode, indicated by a yellow frame around the viewport. While in “Edit” mode you are able to move (R) the control points and their handles. You also have access to a selected point's individual “@ CP” settings. Please read the → “Splines – Quick Start” “Quick Start Workflows - Drawing and Editing Splines” chapter to learn how to shape splines.

Click on “EDIT” and select a control point to change the parameter's settings. “@ CP radial” introduces a force around the control points.
@ CP @ CP vortex
Click on “EDIT” and select a control point to change the parameter's settings. “@ CP vortex” creates a rotational force around the spline's path. Positive values create a clockwise rotation, negative values create a counter-clockwise rotation.
...
Every control point can be linked to another node, e.g. to animate a point's position. Normally, “Null” nodes are used for this purpose, but any other node will work as well. Simply click Click on “-” to open for a node list.
@ CP handle smoothness
With “Smooth” both tangents are affected while moving a single handle. When you switch to “Broken” the tangents can be edited separately.

weighting
When set to “Even” both tangents have the same influence on the spline's curvature. With “Uneven” the tangents' influence is treated individually.
