How do i test run my new mod?

[Drachenbauer]

Hello

 

I have two mods open in my eclipse workspace.

Now i noticed, no matter, what i try to setup a test run for my new flat-tiles-mod, it tries to run the old Angry-Birds-mod.

How do i tell eclipse, that it should run the new mod now?

Edit:

Now it does not more load the old mod, but it also does not load the new mod into the test-client.

I believe you should be able to right-click on the project in your package/project manager, and select "Run As" to get the options to run using that project.

[Drachenbauer]

that was, what i did.

 

Now i noticed, that i missed some fines like mod.toml in the new one.

i copyed them from the other one, and changed the date inside tham to match my new one, and now i test again.

[Ugdhar]

Make sure you have run the gradle task genEclipseRuns for your new project as well, if you're just copying files over, I would guess it's possible that running the new project could still target the original one.

[Drachenbauer]

i used that gradle task.

[Drachenbauer]

Now i get other errors:

But i don´t know, where it means "null-name" My blocks have names: black_concrete_tile_block, blue_concrete_tile_block, and so on.

For the block java file, i use the setup from the carpet-block.

 

Now i noticed, this setup gives o registra name.

How do i add a registry name to this:

    public static void registerBlocks(final RegistryEvent.Register<Block> event)
        {
            event.getRegistry().registerAll(FlatTilesBlocks.black_concrete_tile_block = new ConcreteTileBlock(DyeColor.BLACK,
                                            Block.Properties.create(Material.ROCK, MaterialColor.BLACK).sound(SoundType.STONE).
                                            lightValue(0).hardnessAndResistance(1.8f, 9f).variableOpacity()),
                                            FlatTilesBlocks.blue_concrete_tile_block = new ConcreteTileBlock(DyeColor.BLUE,
                                            Block.Properties.create(Material.ROCK, MaterialColor.BLUE).sound(SoundType.STONE).
                                            lightValue(0).hardnessAndResistance(1.8f, 9f).variableOpacity()),
                                            FlatTilesBlocks.brown_concrete_tile_block = new ConcreteTileBlock(DyeColor.BROWN,
                                            Block.Properties.create(Material.ROCK, MaterialColor.BROWN).sound(SoundType.STONE).
                                            lightValue(0).hardnessAndResistance(1.8f, 9f).variableOpacity()));
        }

theese are three blocks so far.

[Ugdhar]

You need to set the registry name of your stuff before you register them.

 

 

[Drachenbauer]

This is thr block-registry now:

    public static void registerBlocks(final RegistryEvent.Register<Block> event)
        {
            event.getRegistry().registerAll(FlatTilesBlocks.black_concrete_tile_block = new ConcreteTileBlock("black_concrete_tile_block", DyeColor.BLACK,
                                            Block.Properties.create(Material.ROCK, MaterialColor.BLACK).sound(SoundType.STONE).
                                            lightValue(0).hardnessAndResistance(1.8f, 9f).variableOpacity()),
                                            FlatTilesBlocks.blue_concrete_tile_block = new ConcreteTileBlock("blue_concrete_tile_block", DyeColor.BLUE,
                                            Block.Properties.create(Material.ROCK, MaterialColor.BLUE).sound(SoundType.STONE).
                                            lightValue(0).hardnessAndResistance(1.8f, 9f).variableOpacity()),
                                            FlatTilesBlocks.brown_concrete_tile_block = new ConcreteTileBlock("brown_concrete_tile_block", DyeColor.BROWN,
                                            Block.Properties.create(Material.ROCK, MaterialColor.BROWN).sound(SoundType.STONE).
                                            lightValue(0).hardnessAndResistance(1.8f, 9f).variableOpacity()));
        }

 

The item-registry:

    public static void registerItems(final RegistryEvent.Register<Item> event)
        {
            
            event.getRegistry().registerAll(FlatTilesItems.black_concrete_tile_block = new BlockItem(FlatTilesBlocks.black_concrete_tile_block,
                                            new Item.Properties().defaultMaxDamage(0).group(FLAT_TILES).maxStackSize(64).rarity(Rarity.COMMON).
                                            setNoRepair()).setRegistryName(FlatTilesBlocks.black_concrete_tile_block.getRegistryName()),
                                            FlatTilesItems.blue_concrete_tile_block = new BlockItem(FlatTilesBlocks.blue_concrete_tile_block,
                                            new Item.Properties().defaultMaxDamage(0).group(FLAT_TILES).maxStackSize(64).rarity(Rarity.COMMON).
                                            setNoRepair()).setRegistryName(FlatTilesBlocks.blue_concrete_tile_block.getRegistryName()),
                                            FlatTilesItems.brown_concrete_tile_block = new BlockItem(FlatTilesBlocks.brown_concrete_tile_block,
                                            new Item.Properties().defaultMaxDamage(0).group(FLAT_TILES).maxStackSize(64).rarity(Rarity.COMMON).
                                            setNoRepair()).setRegistryName(FlatTilesBlocks.brown_concrete_tile_block.getRegistryName()));
        }

In the official minecraft files i found no hint, that the carpet uses a special blockitem-class, so i use  instances from the commen blockitem-class for the blockitems of the tiles.

 

and this is the block java:

package drachenbauer32.flattilesmod.blocks;

import drachenbauer32.flattilesmod.util.Reference;
import net.minecraft.block.Block;
import net.minecraft.block.BlockState;
import net.minecraft.block.Blocks;
import net.minecraft.item.DyeColor;
import net.minecraft.util.Direction;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.math.shapes.ISelectionContext;
import net.minecraft.util.math.shapes.VoxelShape;
import net.minecraft.world.IBlockReader;
import net.minecraft.world.IWorld;
import net.minecraft.world.IWorldReader;

public class ConcreteTileBlock extends Block {
   protected static final VoxelShape SHAPE = Block.makeCuboidShape(0.0D, 0.0D, 0.0D, 16.0D, 1.0D, 16.0D);
   private final DyeColor color;

   public ConcreteTileBlock(String name, DyeColor p_i48290_1_, Block.Properties properties) {
      super(properties);
      setRegistryName(Reference.MOD_ID, name);
      this.color = p_i48290_1_;
   }

   public DyeColor getColor() {
      return this.color;
   }

   public VoxelShape getShape(BlockState state, IBlockReader worldIn, BlockPos pos, ISelectionContext context) {
      return SHAPE;
   }

   /**
    * Update the provided state given the provided neighbor facing and neighbor state, returning a new state.
    * For example, fences make their connections to the passed in state if possible, and wet concrete powder immediately
    * returns its solidified counterpart.
    * Note that this method should ideally consider only the specific face passed in.
    */
   public BlockState updatePostPlacement(BlockState stateIn, Direction facing, BlockState facingState, IWorld worldIn, BlockPos currentPos, BlockPos facingPos) {
      return !stateIn.isValidPosition(worldIn, currentPos) ? Blocks.AIR.getDefaultState() : super.updatePostPlacement(stateIn, facing, facingState, worldIn, currentPos, facingPos);
   }

   public boolean isValidPosition(BlockState state, IWorldReader worldIn, BlockPos pos) {
      return !worldIn.isAirBlock(pos.down());
   }
}

 

I get no more error messages, but the items for the blocks don´t appear in the Creative inventory tab, that i made for them...

 

In the official minecraft files

 

What is not correct now?

Edited January 19, 2020 by Drachenbauer

[Ugdhar]

Your code is super hard to read with all of those method calls chained together, but I don't see anything that sets the creative tab (called ItemGroup I believe in the current supported versions) anywhere.

[Drachenbauer]

My creativetab is another class, that i just didn´t post here, because in the other mod it worked so far.

 

I took all about it from the other mod.

So i think, the problem is not about the creative tab itself.

 

maybe something about the json's:

base for the flat tiles:

{   "parent": "block/thin_block",
    "elements": [
        {   "from": [ 0, 0, 0 ],
            "to": [ 16, 1, 16 ],
            "faces": {
                "down":  { "uv": [ 0,  0, 16, 16 ], "texture": "#material", "cullface": "down" },
                "up":    { "uv": [ 0,  0, 16, 16 ], "texture": "#material" },
                "north": { "uv": [ 0, 15, 16, 16 ], "texture": "#material", "cullface": "north" },
                "south": { "uv": [ 0, 15, 16, 16 ], "texture": "#material", "cullface": "south" },
                "west":  { "uv": [ 0, 15, 16, 16 ], "texture": "#material", "cullface": "west" },
                "east":  { "uv": [ 0, 15, 16, 16 ], "texture": "#material", "cullface": "east" }
            }
        }
    ]
}

 

one specific block:

{
    "parent": "flattilesmod:block/tile",
    "textures": {
        "particle": "block/blue_concrete",
        "material": "block/blue_concrete"
    }
}

 

Blockstates for this block:

{
    "variants": {
        "": { "model": "flattilesmod:block/blue_concrete_tile" }
    }
}

 

Blockitem:

{
    "parent": "flattilesmod:block/blue_concrete_tile"
}

 

Is there some issue?

Please show where you assign the item to the ItemGroup

[Drachenbauer]

It´s in the item registry, that i posted above.

It includes

group(FLAT_TILES)

for each item

[Ugdhar]

You should really post your entire codebase as a github repository, because not seeing everything makes it so much harder to see what's wrong.

 

What is FLAT_TILES?

[Drachenbauer]

Quote

What is FLAT_TILES?

 

My selfmade itemgroup.

[Ugdhar]

Well, given the information I have, I would have to say there's something wrong with it if it's not working.

Just for grins, if you change FLAT_TILES to ItemGroup.MISC does it add your items to the Miscellaneous tab? If that works, then your custom tab is broken.

[Drachenbauer]

also i noticed, that the tab of this shows no title-item-icon.

 

Edit: the items don´t appear in the misc-tab, too

Then I would question if the items are even being registered. I guess post logs?

[Drachenbauer]

Here is now my git-repository:

https://github.com/Drachenbauer/FlatTilesMod

 

Edit:

the commented areas in the main-class and the class for the custom creative tab are from a tabsorter, that i actually deactivated.

I´ll reactivate it, if the items work.

Edited January 19, 2020 by Drachenbauer

[Ugdhar]

Just out of curiosity, what happens if you change the icon in your FlatTilesItemGroup to a vanilla item, instead of one of your modded items? I'm just curious if the issue is arising because your item is not registered yet, therefore does not exist, so your tab isn't getting setup?

Check out https://mcforge.readthedocs.io/en/1.14.x/concepts/registries/#injecting-registry-values-into-fields for info on ObjectHolders.

 

Also. . . . .

[Drachenbauer]

If my item is not registered, i wonder, why...

In 1.14.3 this way to register items worked...

 

Edit:

i noticed, that i forgot a "@SubscribeEvent" above the item registry event.

Now my item appears on the tab from my item-group, but not in it´s inventory-slots.

 

Now i try the item sorter again.

 

I noticed, that I forgot "super.fill(itemStacks);" in the fill-method of my item-group.

 

Now it works.

 

And placing the flat blocks on the ground works too.

 

Now i just have to add blocks of all the materials, i want to have in this mod

and add english and german language naming.

If i test run the flat tiles mod, at first it opens a window to choose a main-class, and then a window, to choose the run-type (client, server, ...) and after this, a minecraft test-window opens, where i can play around with the new content of my mod.

 

But if i now test run the new tulips mod, the seccond window does not appear and i get this error instead:

Quote

2020-02-12 19:36:21,395 main WARN Advanced terminal features are not available in this environment
Exception in thread "main" java.lang.IllegalArgumentException: Environment variable target must be set.
    at net.minecraftforge.userdev.LaunchTesting.main(LaunchTesting.java:51)

I choosed the same option in the first window, as in the other mod.

 

to set up this mod, i copyed the flat tiles mod and renamed it (all folders, wich have the name of the mod, and all appearences of the name and id in files like ".project" and "build.gradle")

and i used the commands "gradlew eclipse" and "gradlew genEclipseRuns".

 

Should i use "gradlew clean" and then the other two again?

 

Edit:

after doing this and a refresh in eclipse, it shown the same behavior as the other one.

Now i can test my new tulip.
