class
View
¶ Defined in Actor.sc.
The View class is an essential part of SCI games. It is the base class for
Prop
,Actor
and the like. It extendsFeature
by providing the ability to be dynamically positioned at different places, and by automatically setting its bounds based on its view, loop and cel. It is often (though not exclusively) used to add static views to the background, via its addToPic method.Example definition:
(instance ship of View (properties x 6 y 92 noun N_SHIP view 113 loop 2 cel 1 signal ignAct ; Don't interact with Actors ) )
Example initialization:
(ship init:)
Subclasses: Prop
.
