BloodyParticles!

Compatibility: works on NeoForge, Forge and Fabric, for Minecraft 1.20.1 and 1.21.1. 100% client-side — install it on your client and join any vanilla server.

In-game config: the NeoForge version has a native config screen and needs nothing extra. For the Forge 1.20.1 and Fabric versions, configuring in-game needs the Cloth Config API (Fabric also uses Mod Menu for the button) — this is optional: the mod works fine without it and falls back to editing the .toml config file.

Add-ons & modded mobs

If you're looking to have the same particle effects with mobs in some popular mods like Born in Chaos, check out my own add-on, which is compatible with many mods. BloodyParticles Add-ons

BloodyParticles

Make every hit feel meaningful. Mobs splash thematic blood and impact particles when damaged — different effects per mob, scaling with attack charge and critical hits.

Features

• 74 vanilla mobs covered out of the box, each with their own thematic effect (zombie redstone-blood, bee honey, blaze flame, axolotl pink-dye, …).
• 100% client-side — works on any vanilla server, no server install needed.
• Runs on NeoForge, Forge and Fabric (Minecraft 1.20.1 and 1.21.1) from a single, unified codebase — same effects on every loader.
• Configurable in-game: config GUI with sliders for intensity, view radius, critical multiplier. English / Spanish.
• Hit-aware: particle count scales with attack charge and critical hits.
• Custom particles: registers its own (e.g. falling feathers for chickens and parrots) with proper sprite-based physics.

This mod is a rework of a datapack that did the same thing but wasn't very user-friendly when it came to scaling the project, nor was it particularly efficient. You can view the datapack here:

This release expands BloodyParticles from a mob-blood mod into a full visual feedback layer for combat, movement, enchantments, and projectiles. Every effect below can be toggled or fine-tuned from the in-game config GUI (Mods → BloodyParticles → Config) — including thresholds, intensities, and texture variants.

Damage Source Variants

Mobs now react to how they're hit, not just that they were hit:

• Fire (flame + small_flame), Lava (flame + lava drops), Drowning (bubble pops), Suffocation (stone block crack)
• Poison → custom green skull smoke (rising, fading)
• Wither → custom black skull smoke
• Freezing → custom snowflakes (rotating, drifting)

Defaults apply to every mob automatically. Addon resourcepacks can override per mob.

Animated Custom Particles

Custom particles now support multi-frame animation via standard mcmeta. Drop name_0.png, name_1.png, … and list them in the particles JSON — feather, skulls, snowflake, and ender pearl particles all animate automatically when given multiple frames.

Low-HP Visuals

• Red vignette overlay with two texture variants (V1 subtle / V2 bloody) and configurable HP threshold (1–99%).
• Blood particles that pulse sparsely below the threshold and become continuous below half-threshold, with adjustable intensity.

Player Movement Effects

• Sprint trail — campfire smoke behind you, with configurable warmup time. Works while riding a mount (horse galloping). Auto-skipped on ice and snow.
• Falling trail — white smoke streaming behind during freefall.
• Landing burst — smoke + dust + stone shards on impact (3+ block falls).
• Water entry splash — biome-tinted water chunks + snow foam + dolphin sound on jumping into water.

Each can be toggled independently.

Shield Block

Wood + crit particles project forward in your look direction when blocking an attack — fully reliable even when the shield absorbs 100% of damage, and it works for any item that blocks the vanilla way, including modded shields.

Enchanted Arrows (Bow)

• Flame: fire + smoke trail; bigger flame + lava + large_smoke burst on mob impact.
• Power: enchanted_hit + witch trail (count scales with level); sweep_attack + dragon_breath burst on impact.
• Detection works for any combination of both enchants on the same arrow.

Fire Aspect (Sword)

Melee hits with a Fire-Aspect-enchanted weapon trigger the same flame burst as Flame arrows.

- Knockback / Punch Wave;

Shockwave with swords and a bow, featuring the knockback and punch enchantments.

Boot Enchantments

• Feather Falling — 2–5 feathers on landing.
• Frost Walker — snowflakes + occasional end_rod sparks at your feet over water.
• Soul Speed — soul + dust_plume on soul sand / soul soil. Configurable intensity.
• Depth Strider — bubble, fishing, dolphin, and small white air particles around your legs underwater. Configurable intensity.

Ender Pearl

• Custom wave_enderpearl anchored at each pearl tick — grows + fades, creating a "tunnel" along the pearl's path.
• Custom dot_enderpearl scattering with dispersion.
• Portal + occasional dragon_breath as the magical undertone.
• Teleport burst of all of the above when the pearl impacts and teleports you.

On-Fire

Any burning mob (or player) emits flames and smoke. Fire-immune mobs (blaze, magma cube, ghast, wither) are skipped automatically. Configurable intensity.

---

Everything is configurable

The mod ships with an in-game config screen (native on NeoForge; via Cloth Config on Forge and Fabric) — every feature in this list has its own toggle, and many expose sliders for thresholds, frequencies, and intensity.

• Don't like an effect? Disable it.
• Want it more dramatic? Crank the slider.
• Hot-reloadable from the GUI: changes apply instantly without restarting.

v4.0 - What's new

- Now on NeoForge, Forge and Fabric

BloodyParticles used to be NeoForge-only. It now runs on NeoForge, Forge and Fabric, for Minecraft 1.20.1 and 1.21.1 — the same feature set on every combination. The whole mod was reworked onto a single shared codebase (Architectury + Stonecutter), so effects behave identically across loaders and new Minecraft versions are much cheaper to support going forward.

- In-game config on every loader

• NeoForge: native config screen, no extra mods.
• Forge 1.20.1 / Fabric: in-game config through Cloth Config (Fabric also uses Mod Menu for the button). Optional — without them the mod still works and reads its .toml.

- Reworked shield-block detection

The result is rock-solid in both singleplayer and multiplayer, and it now works automatically with modded shields — any item that blocks the vanilla way triggers the effect, with no per-item setup.

- Multiplayer verified on all loaders

The full client-side multiplayer layer (other players' movement, enchantment, projectile and combat effects) is verified across all four loader/version combinations — still 100% client-side, still compatible with any vanilla server.
