If I have a BlockPos, how can I tell if it's a full-height block (ie, not farmland, not bottom slab, but top slab would return true)?  Essentially if the block at that location could support spawning (ignoring transparency and air above it, I've tested for those - I just need to verify the shape height).

Depending upon what you are doing there is more you need to do with this.

 

You should really be using SpawnPlacements.checkSpawnRules().

That way you will include the rules defined by vanilla and mods for their blocks and entities.

As part of it, it uses BlockStateBase.isValidSpawn(), which by default uses BlockStateBase.isFaceSturdy(). That is essentially what you asked for but not the complete answer.

 

You can also look at NaturalSpawner and BaseSpawner if you are interested in the full logic for mob spawning.

e.g. firing the forge events canEntitySpawn() and doSpecialSpawn() to allow other "3rd party" mods to apply their policies to spawns for entities they didn't write (such as vanilla mobs).

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

      how to fix this sodium error thing?

      By artyl23 · Posted

      Ensure your system is running the latest version of Java. Sodium requires Java 17 or later for newer Minecraft versions (like 1.17+).

      [1.20.1]How to make entity holds items (rendering issue)

      By sakiika · Posted

      Hi I wanted to my custom mob to hold any sword item, but didn’t rendered properly.   In entity class, make entity hold items as below: @Override public InteractionResult mobInteract(Player pPlayer, InteractionHand pHand) { //… ItemStack itemstack = pPlayer.getItemInHand(pHand); if (this.isTame()) { if ( (itemstack.is(Items.MELON_SLICE) || itemstack.is(Items.HONEY_BOTTLE)) && this.getHealth() < this.getMaxHealth() ) { //… } /* Handle holding sword */ else if (itemstack.getItem() instanceof SwordItem) { pPlayer.displayClientMessage(Component.literal("Clicked with item: " + itemstack.getDisplayName().getString()).withStyle(ChatFormatting.GOLD), true); //Return sword //pPlayer.getInventory().add(this.getItemInHand(InteractionHand.MAIN_HAND)); pPlayer.getInventory().add(this.getItemBySlot(EquipmentSlot.MAINHAND)); //The entity holds item //this.setItemInHand(InteractionHand.MAIN_HAND, itemstack); this.setItemSlot(EquipmentSlot.MAINHAND, itemstack.copy()); //Give copy of itemstack //If player is not in creative mode. From mobInteract() in wolf. if (!pPlayer.getAbilities().instabuild) { //Decrement sword count in hand pPlayer.getItemInHand(pHand).shrink(1); } return InteractionResult.SUCCESS; } else { //If player is sneaking pPlayer.displayClientMessage(getItemInHand(InteractionHand.MAIN_HAND).getDisplayName(), false); if (pPlayer.isShiftKeyDown()) { //Return sword //pPlayer.getInventory().add(this.getItemInHand(InteractionHand.MAIN_HAND)); pPlayer.getInventory().add(this.getItemBySlot(EquipmentSlot.MAINHAND)); //The entity holds nothing this.setItemInHand(InteractionHand.MAIN_HAND, ItemStack.EMPTY); return InteractionResult.SUCCESS; } else { //… } } else { return interactionresult; } }   And in render class, render the item as below: @Override public void render(RanaEntity pEntity, float pEntityYaw, float pPartialTicks, PoseStack pMatrixStack, MultiBufferSource pBuffer, int pPackedLight) { if(pEntity.isBaby()) { pMatrixStack.scale(0.5f, 0.5f, 0.5f); } model.setupAnim(pEntity, 0, 0, 0, pEntityYaw, 0); // //Get location and rotation of arm bone ModelPart rightArm = model.rightArm(); //Get right arm //Get location and rotation of item according to arm bone pMatrixStack.pushPose(); pMatrixStack.translate(rightArm.x, rightArm.y, rightArm.z); //Move to bone location pMatrixStack.mulPose(Axis.XP.rotationDegrees(rightArm.xRot)); //Rotate X pMatrixStack.mulPose(Axis.YP.rotationDegrees(rightArm.yRot)); //Rotate Y pMatrixStack.mulPose(Axis.ZP.rotationDegrees(rightArm.zRot)); //Rotate Z //Draw item //ItemStack itemStack = pEntity.getItemInHand(InteractionHand.MAIN_HAND); ItemStack itemStack = pEntity.getItemBySlot(EquipmentSlot.MAINHAND); if (!itemStack.isEmpty()) { //Offset pMatrixStack.translate(0.0, 0.0, 0.1); // Render the item //Minecraft.getInstance().getItemRenderer().renderStatic(itemStack, ItemDisplayContext.THIRD_PERSON_RIGHT_HAND, pPackedLight, OverlayTexture.NO_OVERLAY, pMatrixStack, pBuffer, pEntity.level(), pEntity.getId()); //itemRenderer.renderStatic(itemStack, ItemDisplayContext.THIRD_PERSON_RIGHT_HAND, pPackedLight, OverlayTexture.NO_OVERLAY, pMatrixStack, pBuffer, pEntity.level(), pEntity.getId()); itemInHandRenderer.renderItem(pEntity, itemStack, ItemDisplayContext.THIRD_PERSON_RIGHT_HAND, false, pMatrixStack, pBuffer, pEntity.getId()); } pMatrixStack.popPose(); super.render(pEntity, pEntityYaw, pPartialTicks, pMatrixStack, pBuffer, pPackedLight); }   I confirmed the entity can properly hold item(logically) but the item which the entity holds is not rendered at all.   Full code: https://github.com/sakiiiiika/ranamod   Thanks.
