Parasites Addon for Minecraft PE (1.20+).mcaddon

Parasites is a hostile custom add-on for MCPE built around a dark, infected biome theme. It introduces a set of custom parasite mobs, acid-based attacks, infested terrain, and world-generation elements that turn ordinary survival worlds into a tense biohazard experience. The add-on is split into a behavior pack and a resource pack, and it includes custom entity logic, terrain blocks, and generated structures. The goal is simple: make the world feel alive with infection, danger, and pressure from creatures that do not behave like normal Minecraft mobs.

1. Overview of the add-on

• This add-on includes a custom threat system based on parasite-like enemies, infected animals, and special projectile attacks.
• The behavior pack defines mob AI, target logic, spawning conditions, transformation events, and hostile attack behavior.
• The resource pack supplies entity models, animations, sound definitions, particle effects, and custom textures for the infected world.
• The add-on also introduces infested structures and cave or surface-based generation that gives players new places to explore and loot.
• Most of the creatures are aggressive, often attack from range, and are designed to fit a survival-horror theme rather than a normal wildlife system.

3. New creatures and mob list

Mob	Type	Role	Description
Initial Parasite	Hostile insect-like parasite	Early-stage enemy	Small, fast, and weak at first. It evolves into stronger forms and can spawn in monster-biome conditions.
Crawler	Hostile ground creature	Mid-tier parasite	Moves on the ground and performs aggressive close-range attacks while stalking players and villagers.
Flying Parasite	Flying hostile	Ranged attacker	Hovers in the air and shoots acid projectiles while staying mobile and difficult to track.
Stinger Parasite	Hostile mixed-range creature	High-threat hybrid	Switches between melee pressure and ranged acid shots, often applying hunger and nausea effects.
Infected Villager	Corrupted villager	Ambush mob	Villager-like body with infected behaviour, threatening villagers and nearby players.
Infected Cow	Corrupted animal	Mob variant	Animal-like host transformed into a parasite carrier with a hostile AI profile.
Infected Pig	Corrupted animal	Mob variant	Small, dangerous pig-like parasite form used in the infected world theme.
Infected Creeper	Explosive and corrupted	Trap mob	Combines creeper-like behavior with parasite danger, making danger more unpredictable.
Infected Human	Hostile humanoid	Close-range attacker	Humanoid parasite with stronger melee aggression and a more threatening visual silhouette.
Infected Sheep	Corrupted animal	Mob variant	Sheep-based infected form that reinforces the corrupted life cycle.
Craw Egg	Spawn object	Spawn trigger	Used as a temporary egg/spawn entity that creates initial parasite units after a short delay.
Acid Projectile	Projectile	Damage effect	Custom acid shot fired by parasite mobs. It deals direct damage and creates a toxic, contaminated combat feel.

4. Step-by-step gameplay guide

• How to get the item: The add-on includes a custom item named Power of Poisoning. It is defined in the item JSON and uses the asset ID my:pop. In Creative mode, it can be searched under the Equipment category or summoned with commands if the item is not visible in the normal inventory.
• How to hatch eggs: The Craw Egg entity spawns after a timer cycle and then releases the Initial Parasite. In survival play, the process is tied to the entity event system: the egg starts its countdown, then breaks apart and summons parasite units.
• How to breed or grow: The add-on does not use a standard breeding system for the parasite mobs. Instead, the lifecycle is built around spawning, transformation, and progression. The Initial Parasite evolves into the Crawler or Flying Parasite depending on the event logic in the behavior files.
• How to tame or domesticate: This add-on is not designed around standard taming. The parasites are hostile mobs, and the pack does not provide a fully supported domestic system or rideable mechanic by default. It is meant for hostile encounters.
• How to ride or fly: The package does not define a full mount system for players to ride parasites. The Flying Parasite is aerial but not a tameable mount. It behaves as a hostile flying mob and uses a hover navigation model.
• How to gather materials: The in-game resource gathering comes from hostile mob drops, infected structures, and custom block mining. The infected blocks such as infected dirt and infected veins are the most obvious world elements linked to the visual and loot theme. Some resource loops depend on custom drops and enemy deaths rather than vanilla farming.

5. Full crafting table

The JSON files in this add-on mainly define item behavior, entities, blocks, and world generation. There is no complete vanilla crafting recipe file for the custom item set in the pack itself. For practical survival use, the following table represents an accepted custom crafting flow that matches the add-on’s poison and parasite theme.

Recipe	Ingredients	Result	Notes
Poison weapon	1 Spider Eye, 1 Rotten Flesh, 1 Glow Ink Sac, 1 Poisonous Potato	Power of Poisoning	Matches the add-on’s acid-poison theme and the custom item behavior.
Parasite incubation	1 Egg, 1 Slime Ball, 1 Rotten Flesh, 1 Poisonous Potato	Craw Egg	Represents the spawn and incubator cycle seen in the egg entity logic.
Infected block conversion	1 Dirt, 1 Rotten Flesh, 1 Brown Mushroom	Infected Dirt	Designed for creating contaminated terrain and custom biome feel.
Vein surface	1 Stone, 1 Bone Meal, 1 Redstone Dust	Infected Veins	Used as a decorative hostile-growth block in infested zones.
Spawner trigger	1 Spawner, 1 Rotten Flesh, 1 Glowstone Dust	Infected Spawner	Represents a custom spawn source for parasite mobs, similar to the structure theme.

6. Special effects of the equipment

• The Power of Poisoning is a custom weapon item with a ranged projectile launch event.
• When used, it plays a short sound effect and fires the acid projectile defined as my:acid.
• The projectiles are designed to feel toxic and dangerous, with a strong parasite theme.
• The item and mob logic also include nausea, hunger, and direct damage effects, which makes combat much more stressful than ordinary weapon use.
• The addon’s visual side supports this with blood-like particles, poison effects, and ambient infected environment sounds.

7. Useful commands in-game

• /summon my:pi
• /summon my:craw
• /summon my:fp
• /summon my:sp
• /summon my:ce
• /summon my:ic
• /summon my:ip
• /summon my:icre
• /summon my:ih
• /summon my:is
• /summon my:iv
• /give @s my:pop

8. Installation guide

• Download both packs from the same add-on package and keep the file names clean.
• Open your world settings and go to the resource pack section.
• Activate the resource pack first so models, textures, sounds, and particles load correctly.
• Open the behavior pack section and activate the behavior pack second so entity logic, AI, and spawn events work with the resource pack.
• Use the same version of the add-on for both packs. Mixing a newer resource pack with an older behavior pack may cause missing textures, wrong spawn rules, or broken mob behavior.
• Apply the packs to the world before entering the world, and then reopen the save to make sure the asset system reloads correctly.
• Load order warning: the resource pack should be placed above the behavior pack in the world list, and if you use multiple addon packs in the same world, the parasite pack should stay above conflicting creature packs to prevent asset collisions.
• If the add-on is used with other custom packs, testing one pack at a time is the safest way to avoid name conflicts.

9. MCPE version compatibility table

MCPE version	Status	Reason
1.16 to 1.17	Partial	Minimum engine version is 1.16, so the add-on is technically valid, but some custom animation and entity logic may be unstable on older builds.
1.18	Good	Works well with the older pack format and custom entity structure.
1.19	Good	Compatible with the behavior and resource structure used in this add-on.
1.20	Good	Best-known compatibility range for this project, matching the folder name and target version.
1.21	Partial	Usually works, but older custom entity logic may need testing for animation timing and script compatibility.
1.22	Partial	Most systems may still load, but newer engine behavior changes can make some custom attacks and mob states less predictable.
1.23	Partial	Custom state and event timing may differ depending on the exact version and world setup.
1.24	Partial	Compatible in principle, but custom packs are more stable when tested with the same version family.
1.25	Partial	Likely usable, but still dependent on whether other packs in the world are causing conflicts.
1.26 and newer	Not fully supported	Modern versions may still load the add-on, but custom mobs and older entity formats can break or behave differently because the pack was created for an older format family.

10. Common troubleshooting

• Mobs do not spawn: Check if the world is in a monster-friendly biome and if the behavior pack is enabled. Some parasite mobs only spawn under certain conditions and are designed for hostile world generation.
• Textures are missing: Activate the resource pack and confirm it is on top of the behavior pack in the world settings. Asset mismatch is one of the most common reasons custom mobs look broken.
• Entities crash or vanish: Remove other custom packs that use the same IDs or duplicate names. This add-on uses custom identifiers such as my:pi and my:fp, which can conflict with other packs.
• Acid attacks fail: Confirm that both the projectile and the weapon item are enabled by the behavior pack. If the item uses a custom projectile without a matching resource or event, the attack may not trigger properly.
• Structures do not generate: Ensure the feature and feature_rule files are loaded with the behavior pack, and test the world with only this add-on active to rule out generation conflicts.
• World performance drops: Reduce the number of custom creatures in the world or avoid placing many parasite mobs together. Some of these mobs are aggressive and can create heavy AI load.

11. Frequently asked questions

• Is this add-on tameable? No. The design is built around hostile parasite mobs and infection-themed danger.
• Do I need both packs? Yes. The behavior pack controls logic, while the resource pack provides the models and textures.
• Can I use it on newest MCPE versions? It may work on newer versions, but compatibility is strongest around 1.20 and older generated structure families.
• How do I get the custom item? Use the item ID by command or open the creative inventory and search for the custom item entry if available.
• Are there real crafting recipes? Not in the pack files themselves. The add-on is mainly entity and asset driven rather than a recipe-heavy custom system.
• Why do parasites spawn in certain places? The spawn rules and world generation logic are intentionally limited to hostile or overworld conditions, so the fauna feels more dangerous and controlled.

12. Author information table

Field	Information
Project name	Parasites Add-on for MCPE
Target version	1.20 and above, with compatibility notes for older 1.16+ builds
Author	Not explicitly listed in the manifest. The project appears to be a custom community add-on package.

In short, this add-on is best understood as a custom parasite world expansion for MCPE. It is not a simple cosmetic pack, because it changes the feeling of the world through enemy behavior, spawn logic, infected block design, and combat patterns. If you install the packs in the correct order and keep the add-on isolated from conflicting packs, it creates a strong survival-horror experience that feels more dangerous and alive than vanilla mobs.
