CombatEffects
CombatEffects replaces and extends the visual particles that appear during fights, from charged bow shots to damage numbers, for Fabric on 1.21.6 – 1.21.8.
What it does
Charging bows and tridents show blue particles, and projectile throws or shots release directional shockwave particles. Critical hits draw reworked spark effects, and a potion cloud appears where a thrown potion breaks on a solid block. Damage numbers use a font modeled on the one in Minecraft Dungeons, and healing shows a glowing ring around the entity that gains health. Sprinting leaves cloud particles, freezing shows snowflakes, and weakness shows purple clouds.
Breaking another entity's shield on cooldown releases a large burst of shield particles. Entity trails can be defined through data-driven JSON files in a resource pack, and trail entities can be registered for any type in the minecraft:impact projectiles tag. Each effect can be switched on or off in the mod's config, which requires MidnightLib. CombatEffects is client-side only, so servers run without it, and it is released under All rights reserved; the source code is public.
Key features
Charging and projectile effects
Blue charging particles appear while bows and tridents are drawn, and shockwaves mark each throw or shot.
Reworked critical hit sparks
Critical hits show fiery sparks in a redesigned style, replacing the default critical particles.
Damage numbers and healing rings
Damage numbers use a Minecraft Dungeons style font, and healing shows a glowing ring on the gaining entity.
Shield break and status clouds
Breaking a shield on cooldown releases a large burst, and sprinting, freezing and weakness each add their own cloud or flake effect.
