Radar Plugin radar.swf / radar.js

• The radar plugin shows the current viewing cone / area.
• It can be used on a floor map image to show the current viewing direction and field of view on it. Use the parent attribute to align in on a map image. By using maskchildren="true" on the parent element it's possible to draw the radar cone only with the parent layer.
• The pano viewing direction can be changed by dragging the radar cone with the mouse (but could be disabled by adding enabled="false").
• The position and size of it can by adjusted with the standard plugin attributes.

Syntax

Usage Example:

<plugin name="radar"
        url.flash="radar.swf"
        url.html5="radar.js"
        parent="map"
        align="lefttop"
        edge="center"
        x="100" y="50"
        scale="5.0"
        heading="0.0"
        headingoffset="90.0"
        fillcolor="0xFFFFFF"
        fillalpha="0.5"
        linewidth="0.0"
        linecolor="0xFFFFFF"
        linealpha="0.3"
        invert="false"
        />

Dynamically set the heading and x/y position:

set(plugin[radar].x, 203);
set(plugin[radar].y, 555);
set(plugin[radar].heading, 91.8);
