Kev's Projectile Immunity Fix
Allows multiple projectiles to hit at the same time but balanced!
About this Mod
📜 Projectile Immunity Fix
Projectile Immunity Fix is a lightweight Fabric mod that balances projectile damage by reworking Minecraft’s invulnerability frames (i-frames) when hit by multiple projectiles, like arrows, thrown weapons, or magic bolts.
In vanilla Minecraft, when a mob is hit by one projectile, it becomes briefly invulnerable (i.e., i-frames) — even if many projectiles hit at once.
⚙️ How It Works
- When an entity (non-player) is struck by a projectile, it temporarily disables invulnerability frames.
- This allows multiple projectiles to fully deal damage without being blocked by hurt cooldowns.
- After a configurable number of projectile hits, a cooldown kicks in, restoring vanilla i-frames temporarily to prevent spamming.
Note: Players are not affected — only mobs and other living entities.
Mods used to test with: Dummy mod, Too Many Bows Mod
🛠️ Configuration
A simple config file (config/projectileimmunityfix.json) is generated on first launch, with the following options:
| Setting | Description | Default |
|---|---|---|
maxHitsBeforeCooldown |
Maximum consecutive projectile hits allowed before normal i-frames return | 10 |
cooldownTicks |
How long (in ticks) the entity is protected after exceeding the max hits | 20 ticks (1 second) |
timeWithoutHitResetTicks |
How long (in ticks) an entity must go without getting hit for the hit counter to reset | 20 ticks (1 second) |
You can adjust these values to make combat faster, slower, or more punishing depending on your pack's balance.
