RS2Object oak = getObjects().closest("Oak tree");
^after doing this ur oak tree will be "oak" in the script and use the above line to define it
so example:
if (oak != null && oak.interact("Chop")) {
^ now it will chop a oak (oak = Oak tree) if u get what i mean ?
also camera change:
getCamera().mouseRotateToYaw((100));
hope this helps you out
