Question

当我编译 LibGdx 项目时，出现以下异常。

我的问题是它为什么会出现以及如何解决这个问题？

更新:我已将我的项目 libgdx 更新为最新版本(每晚构建)，现在我遇到了不同的异常 [com.badlogic.gdx.utils.GdxRuntimeException: Invalid line: ]，异常详细信息如下。

Answer 1

取自最新uiskin.json来自测试。

com.badlogic.gdx.scenes.scene2d.ui.ScrollPane$ScrollPaneStyle: { default: { vScroll: default-scroll, hScrollKnob: default-round-large, background: default-rect, hScroll: default-scroll, vScrollKnob: default-round-large } },

尝试将其插入您的 uiskin.json 中，它可能会起作用。虽然 ScrollPane 有几处更改，但它可能不再适用于旧的 0.9.9。您应该考虑使用最新版本的 libgdx(每晚构建)。
