[1.14] Custom Night Vision Effect

Posted July 22, 20196 yr

Hi, I ran into a problem:

The night vision's effect of brightening up the surroundings is handled in LightTexture#updateLightmap(float partialTicks) and checks for the potion effect, after which a value (usually 1, if the effect is about to expire 0.7 + a sinus curve) is retrieved. How would I implement my own night vision effect, say, at lower intensity? I don't think it's possible to change that vanilla method to account for another check.

Bumping in hope of someone having an idea

AFAIK there is no proper way of doing so.

One wild idea would be to create a custom implementation of LightTexture, and override LightTexture#updateLightmap to take your custom potion effect into account. Then use reflection to change the lightmapTexture field in GameRenderer (from the field gameRenderer in the Minecraft instance from Minecraft#getMinecraft) to an instance of your own LightTexture.

However I am sure this will break many things and might not work as intended.

Personally, I would just use the normal night vision effect.

Some tips:

Modder Support:

Spoiler

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

Support & Bug Reports:

Spoiler

1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

Help with mods/forge please!!!

You’re probably downloading the wrong version of the mod. Decocraft only supports Minecraft 1.12.2, so even if the site lists 1.15.2, that file won’t work with newer versions. Make sure you install Forge 1.12.2 and use the Decocraft 1.12.2 jar in your mods folder. If you want it for 1.15.2, unfortunately, it doesn’t exist — you’ll need to stay on 1.12.2 or find a similar mod for newer versions.

FTBQuests quests not showing in server

Most likely, this is no longer relevant for you, but I will still leave my answer, because I had the same problem, and I did not find a clear answer anywhere. To ensure your server players have the quests you created, all you need to do is transfer the necessary files to the server. Players don't need to install anything on their end, except for mod. You need to find .minecraft>config>ftbquests>quests. In quests should be folder and two files. So all you need to do is use existing ones or create folders config>ftbquests>quests, and copy the contents of the quests folder.

Maybe an issue with majruszlibrary or a mod requiring it

[1.20.1] Custom Effect Help

Currently stuck on making a custom effect for forge 1.20.1
Im trying to add a certain number of hearts to a player once they consume a potion/custom item, i tried doing it with the vanilla effects and it didn't work the way i wanted it to work, so now im trying to make a custom effect that adds this configurable amount of hearts

So far Ive been following KaupanJoes tutorial for both 1.21 and 1.20 and the effect doesn't seem to give any errors nor does its registration, however i cant seem to get it to work with applying it to the item itself

```package com.curseofaros.item; import com.curseofaros.effect.ModEffects; import net.minecraft.world.effect.MobEffectInstance; import net.minecraft.world.effect.MobEffects; import net.minecraft.world.food.FoodProperties; public class ModFoods { public static final FoodProperties FLASK_OF_LIFE = new FoodProperties.Builder()
.fast() .alwaysEat() .nutrition(0) .saturationMod(0)
.effect(() -> new MobEffectInstance(MobEffects.HEAL, 1, 2), 1.0f) .build();

public static final FoodProperties MEDIUM_POTION = new FoodProperties.Builder() .fast() .alwaysEat() .nutrition(0) .saturationMod(0) .effect(() -> new MobEffectInstance(ModEffects.MEDIUM_POTION_EFFECT.get())) .build();

public static final FoodProperties SMALL_POTION = new FoodProperties.Builder() .fast() .alwaysEat() .nutrition(0) .saturationMod(0) .effect(() -> new MobEffectInstance(MobEffects.HEAL, 1, 3), 1.0f) .build(); }

(Sorry for the real shi formatting, don't really know how to do it smh, note im also fairly new to Java so i don't know a lot, please be patient and let me know if the error is simply a lack of understand of Java principles)
