Hi,

I am trying to see if I can make splines which I can drag and connect to other controls. Similar to the lines you get in Unreal Kismet.

The functionality is similar to a popular line rendering solution for Unity :

The result could be similar to how a GUI solution called EVO GUI for Unity does it.

Please help.

Regards.

For basic shapes you can take a look at the Shapes tutorial here.

For complex shapes you should use the Path element, which uses SVG commands (Path Markup Syntax) to define its shape, for example:

<Path Data="M241.49998,264.49971 C314.49993,277.49971 374.5,397.5 437.5,409.5 500.5,421.5 564.49993,410.49925 583.49972,373.49992 601.23897,338.95531 540.49976,312.49983 533.49976,283.49983 523.0081,358.44328 441.5,358.49999 414.5,284.5 387.5,210.50001 423.9727,183.10478 452.9727,179.10478 481.9727,175.10478 516.63937,193.7711 587.9727,198.10443" Height="236.597" Stretch="Fill" Stroke="Red" Width="347.473"/>

If you need this via API instead of Xaml you must use StreamGeometryContext. It supports Beziers (quadratic and cubic) and Arcs. You can easily create Splines using that primitives.
