Animation accessor used to make objects blink by alternating two of their attributes.
Library: ilvproto
The values will most often be either foreground and background to make whole group flash, or <nodename>.foreground and <nodename>.background so that only a particular node flashes. The periodVal parameter can contain a constant value, the name of another accessor, or an arithmetic expression that can contain accessor names and/or constants (see IlvUserAccessor::getValue()).
If the application uses shared timers (see IlvAnimationAccessor), all the invert accessors are synchronized, which means that all colors are inverted at the same time. Furthermore, when an invert accessor is stopped, the object is always left with its initial color.
| IlvInvertAccessor::IlvInvertAccessor | ( | const char * | name, |
| const IlvValueTypeClass * | type, | ||
| IlvDisplay * | display, | ||
| const char * | periodVal, | ||
| const char * | initialValue, | ||
| const char * | alternateValue | ||
| ) |
Creates a new animation accessor that makes the object blink, by swapping the values of the initialValue and alternateValue parameters.
| name | Accessor name. |
| type | Value type. |
| display | Used to initialize the timers. |
| initialValue | The initial attribute exchanged periodically with alternateValue. |
| alternateValue | The attribute periodically exchanged with initialValue. |
| periodVal | Specifies the interval (in milliseconds) at which initialValue and alternateValue attributes will be swapped (see IlvAnimationAccessor). This parameter can contain a constant value, the name of another accessor, or an arithmetic expression that can contain accessor names and/or constants (see IlvUserAccessor::getValue()). |
|
protectedvirtual |
Performs periodic updates of the accessor.
This method is called repeatedly by the IlvAnimationAccessor object at the time interval specified by the periodVal argument of the constructor. It must be redefined by subclasses to perform a visual or audio animation effect. Its default behavior implements the clock behavior: it triggers regularly the attribute it is attached to.
Reimplemented from IlvAnimationAccessor.
