getWalking().getAStarPathFinder().addObstacle(new PathObstacle("I am an object", "I am its' action", null, null, null));

i tried to add

getWalking().getAStarPathFinder().addObstacle(new PathObstacle("I am an object", "I am its' action", null, null, null));

to the onStart but it gave me an error that "Cannot instantiate the type PathObstacle"

 

i tried 

getWalking().getAStarPathFinder().addObstacle(new PassableObstacle("I am an object", "I am its' action", null, null, null));

but it doesn't seem to work as the char keeps trying to spam click the other side, any ideas? :x
