■ Key Down - an event is triggered as soon as you press the key down.
■ Key Pressed - an event is triggered while the key is pressed. This option
allows you to use a key press event together with Boolean operators. For
example, you can AND this event to a timer event.
On Collision
Selection to Collide With Click the Set button, and use the shortcut menu
to define the collision objects:
■ Clear - clears your currently selected collision objects.
■ Set From Current Selection - sets the collision objects to your current
object selection in the Scene View.
NOTE This option is not available until you make a selection in the Scene
View.
■ Set From Current Selection Set - sets the collision objects to your
current search set or selection set.
Show This is a read-only box, showing the number of geometry objects selected
as collision objects.
Include the Effects of Gravity Check this check box if you want to include
gravity in collision. If this option is used, hitting floor when walking across
it, for example, will trigger your event.
On Hotspot
Hotspot Defines the hotspot type. Choose from:
■ Sphere - a simple sphere from a given point in space.
■ Sphere on Selection - a sphere around a selection. This option doesn't
require you to define the given point in space. This hotspot will move as
the selected objects move in the model.
Trigger When Defines how the event is triggered. Choose from:
■ Entering - an event is triggered when you enter the hotspot. This is useful
for opening doors, for example.
■ Leaving - an event is triggered when you leave the hotspot. This is useful
for closing doors, for example.
■ In Range - an event is triggered when you are inside the hotspot. This
option allows you to use a hotspot event together with Boolean operators.
For example, you can AND this event to a timer event.
