Hello! I've successfully created my first dimension/portal/biome, the whole package. Unfortunately though, the only generation I could figure out how to implement correctly was the regular overworld generation style. I'm interested in finding out how to generate a sky/island dimension that resembles the dimension of Aether or the dimensions of DivineRPG. If anyone has any links/wiki pages where I could read up on this style of world generation, I would be very appreciative! Thanks in advance!

and register it like this

 

DimensionManager.registerProviderType(dimensionID, WorldProviderDimension.class, false);

i myself have copy pasted code so i dont knwo what it does/how it works

and register it like this

 

DimensionManager.registerProviderType(dimensionID, WorldProviderDimension.class, false);

i myself have copy pasted code so i dont knwo what it does/how it works

 

It works and looks close but I'm trying to get more than just one island. I'll try to look into changing that but for now this might do. Thank you again for the src :)

      @Tsuk1 Also, new note, you can use blockbench to make the custom item model for when it is not on the head.   EDIT: Funny story, I am making a mod similar to yours! Mine is called NorseMC.

      Entity reach for custom weapon

      By Unknown_303 · Posted

      @Nood_dev Could you send a screenshot of your weapon code? Here is the one I made (for a dagger): The specific UUID does not matter, just that it is the same every time, which is why UUID#randomUUID does not work public class DaggerItem extends TieredItem implements Vanishable { protected static final double REACH_MODIFIER = -1.5D; protected final Multimap<Attribute, AttributeModifier> defaultModifiers; protected final UUID BASE_ATTACK_REACH_UUID = UUID.fromString("6fe75b5c-9d1b-4e83-9eea-a1d5a94e8dd5") public DaggerItem(Tier pTier, int pAttackDamageModifier, float pAttackSpeedModifier, Properties pProperties) { super(pTier, pAttackDamageModifier, pAttackSpeedModifier, pProperties); this.attackDamage = (float) pAttackDamageModifier + pTier.getAttackDamageBonus(); ImmutableMultimap.Builder<Attribute, AttributeModifier> builder = ImmutableMultimap.builder(); builder.put(Attributes.ATTACK_DAMAGE, new AttributeModifier(BASE_ATTACK_DAMAGE_UUID, "Weapon modifier", this.attackDamage, AttributeModifier.Operation.ADDITION)); builder.put(Attributes.ATTACK_SPEED, new AttributeModifier(BASE_ATTACK_SPEED_UUID, "Weapon modifier", pAttackSpeedModifier, AttributeModifier.Operation.ADDITION)); // THE ONE YOU WANT: builder.put(ForgeMod.ENTITY_REACH.get(), new AttributeModifier(BASE_ATTACK_REACH_UUID, "Weapon modifier", REACH_MODIFIER, AttributeModifier.Operation.ADDITION)); this.defaultModifiers = builder.build(); } @Override public Multimap<Attribute, AttributeModifier> getDefaultAttributeModifiers(EquipmentSlot pEquipmentSlot) { return pEquipmentSlot == EquipmentSlot.MAINHAND ? this.defaultModifiers : super.getDefaultAttributeModifiers(pEquipmentSlot); } }

      Server crash caused by Alex's Caves, Valkyrien Skies, and/or Radium

      That's what we'll try out. I could never figure out how to recreate the crash, so I'll just have to wait and see.

      Model and textures rendered on entity and RenderLevelStageEvent not visible when using shaders

      By Blatopebas · Posted

      Ok, I updated to the latest version and now the models are visible, the problem now is that the glowing eyes are not rendered nor any texture I render there when using shaders, even using the default Minecraft eyes RenderType, I use entityTranslucent and entityCutout, but it still won't render. Something I noticed when using shaders is that a texture, instead of appearing at the world position, would appear somewhere on the screen, following a curved path, it was strange, I haven't been able to reproduce it again. I thought it could be that since I render the texture in the AFTER ENTITIES stage which is posted after the batches used for entity rendering are finished, maybe that was the reason why the render types were not being drawn correctly, so I tried injecting code before finishing the batches but it still didn't work, plus the model was invisible when using shaders, there was a bug where if I look at the model from above it is visible but if I look at it from below it is invisible. So in summary, models are now visible but glowing eyes and textures are not rendered, that hasn't changed.
