The HUD lets you specify the direction and speed of the Wind behavior by dragging an
arrow in a circular region. The direction of the arrow defines the direction of movement
in X and Y space, and the length of the arrow defines speed (velocity). A slider lets you
adjust the scale of the HUD control, increasing or decreasing the effect the control has
over the object.
Press the Shift key while dragging the arrow to constrain the direction to 45-degree angles.
Press the Command key to change the arrow’s direction without affecting its length.
When you click the 3D button, a center arrow control defines the direction the object
is “blown” by the wind in 3D. The Speed slider increases or decreases the velocity of the
blown object.
Note: The maximum speed you can define with the HUD is not the maximum speed
possible. Higher values can be entered into the Velocity parameter in the Behaviors
Inspector.
