Register Block Error

Posted February 24, 201312 yr

I have no errors in eclipse but when I run the game, I keep getting this error:

Here is my main mod file:

	proxy.registerRenderThings();

	EntityRegistry.registerModEntity(EntityRedTailedHawk.class, "RedTailedHawk", 1, this, 80, 3, true);
	EntityRegistry.addSpawn(EntityRedTailedHawk.class, 10, 2, 3, EnumCreatureType.creature, BiomeGenBase.forest, BiomeGenBase.desert, BiomeGenBase.desertHills);

	GameRegistry.registerTileEntity(TileControlStation.class, "tileEntityControlStation");
	GameRegistry.registerBlock(BlockControlStation, "BlockControlStation");

	LanguageRegistry.instance().addStringLocalization("entity.SilentAssassin8_Falconry.RedTailedHawk.name","Red-Tailed Hawk");
	LanguageRegistry.addName(BlockControlStation, "Control Station");

	NetworkRegistry.instance().registerGuiHandler(this, guiHandler);

	registerEntityEgg(EntityRedTailedHawk.class, 0x000000, 0xEB1313);

	BlockControlStation = new BlockControlStation(9000, 0).setBlockName("BlockControlStation");

}

public static int getUniqueEntityId() {

		do {
			startEntityId++;

		return startEntityId;
}	
public static void registerEntityEgg(Class<? extends Entity> entity, int primaryColor, int secondaryColor) {
	int id = getUniqueEntityId();
	EntityList.IDtoClassMapping.put(id, entity);
	EntityList.entityEggs.put(id, new EntityEggInfo(id, primaryColor, secondaryColor));	
}
}

I know that it has to do something with line 51 < GameRegistry.registerBlock(BlockControlStation, "BlockControlStation"); > but I don't know what to do to fix it. Any help would be greatly appreciated.

Your mistake is in this line:

LanguageRegistry.addName("talipBlock", "Talip Block");

Where you do

"talipBlock"

When in quotation marks ("..."), a type is called a String. What you are doing is naming a String. This is not what you should do, which is naming the Object (Block) that you are naming. In this your code should look something like this:

LanguageRegistry.addName(talipBlock, "Talip Block");

In that code you are making a reference to the

public static Block talipBlock;

which is what you want to do.

edit:

Learn java.

This is something that is really recommended before you start modding.

New Forum Design/Update: Issues and Suggestions

Hiho,

first of all I want to say that the new forum design looks really good.

However, there are currently two issues:

In the "Unread" section, the "Mark all as Read" feature seems to be missing - or am I just overlooking it somewhere?
Some threads don’t automatically get marked as read when you open them. So the post still shows up in "Unread," even though you’ve already viewed it.
Example Thread: https://forums.minecraftforge.net/topic/159415-cannot-find-client-log-entries/

Then I have a smaller suggestion, referring to the Text Editor:

It is possible to move out the "Inline Code"-Feature from the "More Formatting Options" and add it directly to the Text Editor Tool Bar?
Same for "Quote"-Feature inside the Create Section

These two features are used quite often (at least by me) - as far as I remember, they were also available in the old forum design.

Trying to boot MC Eternal 2 Server, works on linux not on Windows 11: Jvm args error

That fixed it! it's still being weird and not actually printing anything to CMD but the logs look fine and eventually the gui generated looking normal. Thanks for your help I've done that on linux before but windows servers have always just worked with one click for some reason for me

Make sure you are using Java 17 JDK

In the start script, replace the word "java" with the java 17 path (javaw.exe) and put it into quotation marks
