The 2D HUD lets you specify the direction and speed of the Throw 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 adjusts
the scale of the HUD control, increasing or decreasing the effect of the direction/speed
control.
When you click the 3D button, additional 3D controls become available. The center arrow
now defines the direction the object is thrown in 3D space (X, Y, and Z axes). The Speed
slider lets you increase or decrease the velocity of the thrown object.
In the 2D and 3D Throw HUDs, press the Shift key while dragging the arrow to constrain
it to 45-degree angles. In the 2D HUD, press the Command key to change the arrow’s
direction without affecting its length.
Note: The maximum speed you can define with the HUD is not the maximum possible
speed. Higher values can be entered into the Throw Velocity/Throw Distance parameter in
the Behaviors Inspector.
