试图启动Minecraft mod时出现未知问题（可能是内存）

Question

我正在开发一个Minecraft mod，我对Java非常缺乏经验。当我试图从Eclipse启动mod时，我得到以下错误：

国防部只是简单地添加了一个未设置的项目，但在我添加之前，它给了我同样的错误。

我在Eclipse中也遇到了这个错误，这让我怀疑这个问题与内存有关：

AL lib: (EE) alc_cleanup: 1 device not closed

感谢您的帮助。

Answer 1

JVM内存不足。不管你付出多少，都是不够的。你需要增加它。

注意：此修复程序指定为JVM分配3GB内存，这意味着您的计算机至少需要3GB以上的操作系统内存，因此总共需要4GB或更多内存。

要解决这个问题，请进入JVM参数设置，并将其复制并粘贴到其中：

-Xmx3G -Xms3G -Xmn768m -XX:+DisableExplicitGC -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+UseNUMA -XX:+CMSParallelRemarkEnabled -XX:MaxTenuringThreshold=15 -XX:MaxGCPauseMillis=30 -XX:GCPauseIntervalMillis=150 -XX:+UseAdaptiveGCBoundary -XX:-UseGCOverheadLimit -XX:+UseBiasedLocking -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=15 -Dfml.ignorePatchDiscrepancies=true -Dfml.ignoreInvalidMinecraftCertificates=true -XX:+UseFastAccessorMethods -XX:+UseCompressedOops -XX:+OptimizeStringConcat -XX:+AggressiveOpts -XX:ReservedCodeCacheSize=2048m -XX:+UseCodeCacheFlushing -XX:SoftRefLRUPolicyMSPerMB=10000 -XX:ParallelGCThreads=10

-Xmx3G标志表示JVM获得的最大值。在本例中为3GB。如果JVM再次耗尽内存，您可以进一步增加该值（尽管您仍然受到物理可用量的限制）。

-Xms3G标志表示JVM从多少开始。在这种情况下，还需要3GB。

其余的标志处理优化垃圾收集，这些设置是为Minecraft调整的，摆弄它们实际上可能会让事情变得更糟。
