NAME
Clutter::Behaviour::Path - A behaviour for moving actors along a Clutter::PathSYNOPSIS
my $path = Clutter::Path->new('M 10,10 C 20,20 20,20 10,30 z'); my $behaviour = Clutter::Behaviour::Path->new($alpha, $path); $behaviour->apply($rectangle);
DESCRIPTION
Clutter::Behaviour::Path interpolates actors along a defined path.A path is described by a Clutter::Path object. The path can contain straight line parts and bezier curves. If the path contains 'move-to' nodes then the actors will jump to those coordinates. This can be used make disjoint paths.
When creating a path behaviour in a Clutter::Script, you can specify the path property directly as a string. For example:
{ "id" : "spline-path", "type" : "ClutterBehaviourPath", "path" : "M 50 50 L 100 100", "alpha" : { "timeline" : "main-timeline", "function" : "ramp } }
Note: If the alpha function is a periodic function, i.e. it returns to 0 after reaching the maximum alpha value, then the actors will walk the path backwards to the starting node.
