物理体编辑器错误 [英] Physics Body Editor error

问题描述

尝试从此库初始化 BodyEditorLoader 时出现此错误 http://www.aurelienribon.com/blog/projects/physics-body-editor/

I get this error when trying to initialize BodyEditorLoader from this library http://www.aurelienribon.com/blog/projects/physics-body-editor/

    Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: java.lang.UnsatisfiedLinkError: com.badlogic.gdx.physics.box2d.PolygonShape.newPolygonShape()J
        at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:127)
    Caused by: java.lang.UnsatisfiedLinkError: com.badlogic.gdx.physics.box2d.PolygonShape.newPolygonShape()J

        at aurelienribon.bodyeditor.BodyEditorLoader.<init>(BodyEditorLoader.java:31)

我该如何解决?

推荐答案

基于此https://github.com/libgdx/libgdx/issues/2393 问题是因为在创建形状之前没有加载本地人.

Based on this https://github.com/libgdx/libgdx/issues/2393 the problem is because natives aren't loaded before creating shape.

有两种解决方案:

首先是在创建任何形状之前创建 World 实例.

First is creating World instance before creating any shapes.

其次是在创建任何形状之前调用 Box2D.init();.首选这种方法，因为您不需要创建 World 实例，而且更明显.

Second is calling Box2D.init(); before creating any shapes. This method is preferred because you don't need to create World instance and it's much more obvious.
