📜 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.

🛠️ 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.
