Anomalous Effect
Custom unique effects to help spice up the vanilla gameplay and for content. Free Minecraft Bedrock addon for 26.10.
⬇ Download on CurseForgeThe author built this one for Minecraft 26.10. On other versions it may install and then do nothing.

Introduction
- Shrouding: Hides your health
- Consumption: Eating results in health lost depending on the amount of hunger points you receive
- Frozen: Ice covers your screen and hearts as you take damage every 2 seconds
- Inverted: Sneaking will allow you to jump
- Fumbling: Hides your hotbar
- Phasing: No clip through one layer walls
- Bleeding: Taking damage will take half a heart 3 times every 2 seconds
- Nutrition: Doubles your hunger bar(s) from the amount you receive
- Sunburn: Burn from the sun in daylight
Milk potions aren't an effect, they just remove them.

Shrouding, Consumption, Frozen, Inverted, Fumbling, and Phasing are the only potions obtainable in survival by brewing. The rest of the effects are can be done using the command /seteffect or /ae:seteffect.


The effect has their own color which shows the particle color of the effect, making it easier to know which effect they have.


For command that you don't want to see the pop up message when the command is entered, use command /seteffect_no_message or /ae:seteffect_no_message.
For tags you can give them a tag instead of using the commands. Effect:Frozen-0_45s. Another method for the tag method. Tag options:
- Effect:Frozen-0_45s_p
- Effect:Frozen-0_45s_a
- Effect:Frozen-0_45s_p_a
- Effect:Frozen-0_45s_a_p
- Effect:Frozen-0_1m
- Effect:Frozen-1_45s
"_p" tells that this shouldn't show the particle on the player.
"_a" tells that it's an ambient effect.
"{number}m" tells the script is a minute instead of a second(s).
"-1" is the amplifier which will show Frozen II, so "-3" is Frozen IV.
The effects even have an ambient option.
/ae:seteffect @s bleeding -1 0 true true
the true at the very end is if it's an ambient. If true it shows the ambient one.

The effects work with the other vanilla effects.

The mob effect screen can either be activated by pressing Tab key or on touch screen just click the effect showing on the right side of the screen.

WARNING
If you have touch screen players then use this option instead since the other options don't allow them to close the mob screen.

Compatible Handling
Item Compatibility
For addons that want to be compatible with this addon, I added a few code which handles compatibility.
For your own custom potions, you will need to make your own system to throw the item and give out the item. For the item(s), in minecraft:tags add ae:bottle_1_30s. This tells the script that this item is a bottle with an amplifier of 1 and lasts 30 seconds.
Now after that, add another of what the effect is ae:frozen. This tells the script that the effect is a Frozen effect.
With these it gives us tag Effect:Frozen-1_30s which it gives effect Frozen II 00:30 If the item is a splash or lingering potion then here are theirs ae:splash_1_30s, ae:lingering_1_22s.
You will need to use Script Compatibility to make the Item Compatibility work!
Script Compatibility
For making your custom effect compatible, this part is easy, TagsEqualsEffects holds the tag which must follow the order Effect:{effect_name}. So it should look like this "Effect:Stress": "Stress" For ShowEffectIcons it must match the name of the effect after Effect:{effect_name} and then you include the path to your texture location of the icon for your effect so example "Stress": "textures/mob_effects/stress".
Final part is setting up the color of the effect to indicate which effect it is. EffectParticleColor needs to match the name of the effect after Effect:{effect_name} and then uses hex to determind it's color (the main addon handles it and turns it into r, g, b colors) "Stress": "#0d0d0d".
For your compatible system to work with this addon, copy the format of this script from the code viewer.
import { world, system } from "@minecraft/server";
const TagsEqualsEffects = {
"Effect:Rabies": "Rabies"
};
const ShowEffectIcons = {
"Rabies": "textures/mob_effects/rabies"
};
const EffectParticleColor = {
"Rabies": "#13191b"
};
// DON'T TOUCH ANYTHING BELOW THIS POINT SINCE THIS HANDLES GETTING THE DATA!
const dataPayload = { TagsEqualsEffects, ShowEffectIcons, EffectParticleColor };
const payloadString = JSON.stringify(dataPayload);
let isLinked = false;
const broadcastId = system.runInterval(() => {
if (isLinked) {
world.getDimension("overworld").runCommand(`scriptevent anomalous_effects:link_compatibility DONE`);
system.clearRun(broadcastId);
return;
}
try {
world.getDimension("overworld").runCommand(`scriptevent anomalous_effects:link_compatibility ${payloadString}`);
} catch (e) {}
}, 5);
system.afterEvents.scriptEventReceive.subscribe((event) => {
if (event.id === "anomalous_effects:link_received") {
isLinked = true;
}
});
