Acid Rain

Acid Rain

This mod is very simple and intended for events or survival. It adds acid rain/water damage to the game, affecting players caught in the rain or submerged in water. It’s designed to add a survival challenge, making weather and water sources more dangerous.

Features

• Acid Rain/Water Damage: Players take damage when exposed to rain or submerged in water.
• Player Only: The acid rain only affects players.
• Configurable Damage: The damage amount and interval are configurable via commands.
• Difficulty Scaling: The damage scales with the world difficulty just like damage from mobs.
• Bypasses Armor: Armor is ignored when calculating damage (but protection enchantments still apply).
• No Knockback: The damage does not cause knockback.
• Small Exhaustion: Applies a small amount of exhaustion (0.1 hunger) with each damage tick.
• No Damage Tick Bypass: The damage bypasses the noDamageTicks mechanic, ensuring consistent damage application, even if the player is already taking other forms of damage (like fire).

Commands

The mod includes commands to control the acid rain effect. These commands require operator (OP) permissions (permission level 2 or higher).

• /acid on [interval] [damage] : Enables acid rain/water damage.
• interval: The interval in ticks between each damage application (default is 10 ticks, or 0.5 seconds). Must be an integer of 1 or greater.
• damage: The amount of damage dealt each interval (default is 1.0, or 0.5 hearts). Must be a float of 0.0 or greater.
• Example: /acid on 20 0.5 enables acid rain, dealing 0.5 damage every 20 ticks (1 second).
• If interval and damage are omitted, the default values are used.
• /acid off: Disables acid rain/water damage.
• /acid status: Displays the current status of the acid rain (enabled/disabled), the damage amount, and the damage interval.

Configuration

The mod offers in-game configuration via commands:

• Damage Interval: Adjust the frequency of damage application. A smaller interval means more frequent damage.
• Damage Amount: Control the severity of the acid rain.

Technical Details

• Mod ID: Acid Rain
• Damage Interval: The damageIntervalTicks variable determines how often damage is applied. By default, it’s set to 10 ticks (0.5 seconds).
• Damage Amount: The damageAmount variable determines the base damage applied.
• Tick Handler: The mod registers a ServerTickEvents.END_SERVER_TICK handler that processes all players in all loaded server worlds every tick.
• Custom Damage Type: Uses it’s own damage type.
