Use inner class in btree file #101

Closed Genhis closed 5 years ago

Genhis commented 6 years ago

Issue details

It's not possible to use inner classes in btree file (parser does not allow '$' character used for separating class names).

Reproduction steps/code

  1. Create a public static inner class.
  2. Use full name instead of import in btree file.
  3. com.badlogic.gdx.utils.SerializationException: Error parsing behavior tree on line 3 near: $Inner

OuterClass.java:

package test;

import com.badlogic.gdx.ai.btree.leaf.Success;

public class OuterClass {
    public static class Inner<E> extends Success<E> {}
}

mytree.btree:

root
    selector
        test.OuterClass$Inner
