[1.16.1] Help with Line of Sight checks

Posted August 2, 20205 yr

Hello, I'm trying to implement some logic in my mod that requires to know wether a given set of coordinates is in line of sight of another, in the sense that a straight line can be traced between the two without it being interrupted by any solid blocks. I first thought of ray tracing but I can't find a useful method that can do this nor any piece of documentation regarding this, could anyone help me with that?

Use IBlockReader.rayTraceBlocks(RayTraceContext) method. It does exactly what you need.

(World implements IBlockReader)

Example of usage is at Entity::pick

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)

[1.21.3] How to add effects to food?

game changed the way you create foods.
for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
public static final Consumable GOLDEN_APPLE = defaultFood() .onConsume( new ApplyStatusEffectsConsumeEffect( List.of(new MobEffectInstance(MobEffects.REGENERATION, 100, 1), new MobEffectInstance(MobEffects.ABSORPTION, 2400, 0)) ) )
