I follow the tutorial on website, However, I cannot really complete it.
In the figure of tutorial, they show a human look at a ball and the IK would lead the human’s head to follow the ball. It use a “Target” node, which is a Vector3 input. The node seems can only write the vectors in static, not a exist actor. The result it shows are totally different from how the make the graph.
I tried to add a “actor” as parameter, so the IK node can receive the actor.position from the node. But I can’t not find the node between the actor’s position and IK’s input.
which node I should use between the actor input and the IK node, to retrieve the position of actor node?
