Crash Reading 101

From Pixelmon Wiki
Revision as of 02:49, 18 July 2014 by Some body (talk | contribs)

So I herd you liek crashing? Well good! I am here to help to fix those pesky crashes! Welcome to Crash Reading 101. A "crash" course! Minecraft runs very specifically especially when installing mods and the smallest error, as you know, can cause the mod to crash! >:( but do not fret! I am here to help! Let's start. Here I have gathered a bunch of crashes around the Pixelmon forums and compiled them into one universal tutorial anyone can understand!

Crash reports

The following messages are found under the section that says description near the top of the report. Each bullet point is a separate crash report.

Version 3.2

  • "cpw.mods.fml.common.LoaderException: java.lang.NoSuchFieldError: field_150354_m"

You have the wrong Minecraft and/or Forge version. Pixelmon 3.2 is for Minecraft 1.7.10 using either Forge 10.13.0.1180 or 10.13.0.1186.

Version 3.1.4

  • "java.lang.IllegalStateException: cannot determine the type of the type parameter 'REQ': class cpw.mods.fml.common.network.simpleimpl.SimpleChannelHandlerWrapper"
  • "java.lang.NoClassDefFoundError: net/minecraftforge/common/util/EnumHelper"
  • "java.lang.NoSuchMethodError: net.minecraft.client.gui.ScaledResolution.<init>"
  • at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:192)"

All of these errors occur with incorrect versions of Forge installed. Make sure you are running either Forge 10.12.2.1121 or 10.12.2.1147.

  • "cpw.mods.fml.common.LoaderException: java.lang.ClassNotFoundException: com.pixelmonmod.pixelmon.Pixelmon"

Do not extract the Pixelmon file. Place the entire downloaded file directly into the mods folder.

  • "java.lang.RuntimeException: Unknown character ' ' in"

Delete your Pixelmon.cfg file.

  • "at cpw.mods.fml.common.Loader.preinitializeMods(Loader.java:506)"

You have more than one version of Pixelmon in the mods folder. Only one version of Pixelmon should be in the mods folder at once.

Version 3.0.4

  • "java.lang.NoClassDefFoundError: cpw/mods/fml/common/ICraftingHandler"
  • "cpw.mods.fml.common.LoaderException: java.lang.NoClassDefFoundError: net/minecraftforge/client/event/RenderGameOverlayEvent$Chat"
  • "java.lang.NoSuchMethodError: net.minecraft.launchwrapper.LaunchClassLoader.clearNegativeEntries(Ljava/util/Set;)V"
  • "java.lang.VerifyError: Bad type on operand stack"
  • "java.lang.VerifyError: (class: pixelmon/Pixelmon, method: onServerStart signature: (Lcpw/mods/fml/common/event/FMLServerStartingEvent;)V) Incompatible argument to function"

You have the wrong version of Minecraft, Forge, or both. Pixelmon 3.0.4 runs on Minecraft 1.6.4 using Forge version 9.11.1.965.

  • "cpw.mods.fml.common.LoaderException: java.lang.ClassNotFoundException: pixelmon.Pixelmon"

Do not extract the Pixelmon file. Place the entire downloaded file directly into the mods folder.

  • "java.lang.RuntimeException: Unknown character ' ' in"
  • "java.lang.RuntimeException: Unmatched quote in '/config/pixelmon.cfg:175'"

Delete the Pixelmon.cfg file.

  • "at pixelmon.sounds.Sounds.addPokemonSound(Sounds.java:106)"

Downgrade to Java 1.7.

  • "at net.minecraft.block.Block.<init>(Block.java:349)"

You have item ID conflicts between mods. Modify the offending item IDs or remove the mods that are causing the problem.

  • "at net.minecraft.client.gui.inventory.GuiContainer.func_73863_a(GuiContainer.java:123)"

Not Enough Items does not normally work with Pixelmon. You need to install this patch.

Non-Pixelmon crashes

  • "at net.minecraft.server.MinecraftServer.<init>(MinecraftServer.java:140)"
  • "at net.minecraft.client.Minecraft.func_71371_a(Minecraft.java:2088)"

Add "-Djava.net.preferIPv4Stack=true" to your VM args in the profile you are using. This is found on the Minecraft launcher.

  • "Java Version: 1.6.0_65"

If this shows up in your system details of the Minecraft crash report, you are running the wrong Java and several issues may occur in battle, such as priority and stat boosts becoming negative. Update your Java to 1.7.

If your crash report doesn't match any of these issues, post the full report in the Support Tracker.

I will add more as I find more posts on the forums ^_^ happy crashing. I think...
