Flag Rush Tut. - Player

Troubleshooting General Help

Hey… I'm working on the Flag Rush Tutorial, and I want to add the player (the little gray box). Can someone tell me why there is only the terrain without player? thx

Actually the player is added. It is so small that you could not see it.



Box b = new Box("box", new Vector3f(), 0.35f, 0.25f, 0.5f);



I think you should finish the flag rush tutorial you're reading, because the next part of it is you will add a ChaseCamera which will let you see your player. its like a camera focusing on the player.



somewhat like this.

    private void setChaseCam(){

      Vector3f targetOffSet = new Vector3f();
      targetOffSet.y = ((BoundingBox)playerNode.getWorldBound()).yExtent * 2.0f;

      HashMap props = new HashMap();
      props.put(ThirdPersonMouseLook.PROP_MAXROLLOUT, "8");
      props.put(ThirdPersonMouseLook.PROP_MINROLLOUT, "3");
      props.put(ThirdPersonMouseLook.PROP_MAXASCENT, "" + FastMath.DEG_TO_RAD * 45);
      props.put(ChaseCamera.PROP_INITIALSPHERECOORDS, new Vector3f(7,2,FastMath.DEG_TO_RAD*30));
      props.put(ChaseCamera.PROP_TARGETOFFSET, targetOffSet);

      chaseCam = new ChaseCamera(cam, playerNode, props);
      chaseCam.setMaxDistance(10);
      chaseCam.setMinDistance(2);

    }

thx…but if I add the chase cam, the box is under the terrain… :? Is something wrong with my code…?

try to add a little in the characterMinHeight when you assign it to the player's localTranslation.

float characterMinHeight = tb.getHeight(player.getLocalTranslation()) + ((BoundingBox) player.getWorldBound()).yExtent;
        if (!Float.isInfinite(characterMinHeight) && !Float.isNaN(characterMinHeight)) {
            player.getLocalTranslation().y = characterMinHeight + 0.8f;
        }
