Functions[edit]

Native functions[edit]

AddConnectionTo[edit]

native function AddConnectionTo (SplineActor NextActor)

Create a connection to another SplineActor

BreakAllConnections[edit]

native function BreakAllConnections ()

BreakAllConnectionsFrom[edit]

native function BreakAllConnectionsFrom ()

Break all connections from this SplineActor

BreakConnectionTo[edit]

native function BreakConnectionTo (SplineActor NextActor)

Breaks a connection from this SplineActor to NextActor

FindSplineComponentTo[edit]

native function SplineComponent FindSplineComponentTo (SplineActor NextActor)

Returns the SplineComponent that connects this SplineActor to NextActor. Returns None if not connected

FindSplinePathTo[edit]

native function bool FindSplinePathTo (SplineActor Goal, out array<SplineActorOutRoute)

Find a path through network from this point to Goal, and put results into OutRoute.
