我有一个使用LibGdx版本1.9.9开发的Android游戏,我正在尝试将其导出为HTML。我正在使用GWT(V-2.8.2)。该游戏在Android上运行良好,没有任何问题。通过运行此命令./gradlew html:dist
导出游戏时,我没有遇到任何错误。
但是,当我将导出的库放入本地主机并尝试访问游戏时,首先会出现默认加载程序,然后出现空白屏幕并显示以下错误消息:
GwtApplication: exception: (TypeError) : null is not an object (evaluating 'null.zY')
(TypeError) : null is not an object (evaluating 'null.zY')
在所有浏览器(Safari,Chrome,Firefox)中都会发生这种情况。
堆栈跟踪没有显示任何重要的调试位置。
有什么问题的想法吗?谢谢。
HTML Gradle:
gwt {
gwtVersion='2.8.0' // Should match the gwt version used for building the gwt backend
maxHeapSize="2G" // Default 256m is not enough for gwt compiler. GWT is HUNGRY
minHeapSize="1G"
src = files(file("src/")) // Needs to be in front of "modules" below.
modules 'com.package.gamename.GdxDefinition'
devModules 'com.package.gamename.GdxDefinitionSuperdev'
project.webAppDirName = 'webapp'
compiler {
strict = true;
disableCastChecking = true;
}
}

答案 0 :(得分:2)
进入superdev模式并激活源映射和调试,并逐步在Chrome中浏览源,这就是发现这些问题的方法。
