电磁重炮

为 Factorio 2.0 加入一座重型电磁炮台和专用电磁飞盘弹药。双轨炮管在充能后发射金属飞盘，落点产生蓝白等离子云团、扩散冲击波和逐渐消散的地表余辉。

支持原版和太空时代 DLC。当前版本 0.1.3，已在 Factorio 2.0.77 验证。

特色

• 完整机械动画：充能、发射、护甲展开、风扇散热。
• 三段升调充能声、电磁发射声与冷却泄压声。
• 专用飞盘弹药、蓝白能量核心和渐隐飞行拖尾。
• 基础自动射程 336 格、手动射程 840 格，是普通重炮的 1.5 倍；可使用重炮瞄准遥控器指定目标。
• 爆炸伤害链按原子弹的 5 倍缩放，作用距离按 1.5 倍缩放，伤害外沿约 57 格。
• 中英文物品、配方与科技说明；原创生图图标与统一设计的飞行弹体。

科技与配方

研究顺序：重炮 → 电磁重炮。新科技同时解锁炮台与弹药，研究成本实时复制当前环境的重炮科技。

表中是默认成本；游戏研究成本倍率也会作用于新科技。

弹药制作时间为 15 秒。炮台制作时间沿用默认 0.5 秒。

使用方法

1. 研究重炮，再研究电磁重炮。
2. 制作并放置电磁重炮，装入电磁飞盘弹药。
3. 自动攻击射程内目标，或用重炮瞄准遥控器指定远程目标。
4. 每次射击包含约 2.2 秒充能和后续散热，完整周期约 6 秒。

普通重炮继续使用原版炮弹，电磁重炮只接受电磁飞盘弹药。

爆炸会伤害友军。爆炸结束时清理范围内尸骸、悬崖与铺装；水面、岸线和填海地基保留。起爆有短促蓝白闪光，中心余辉约 35 秒渐隐。

安装与升级

将 electromagnetic-siege-cannon_0.1.3.zip 放入 Factorio 的 mods 目录并启用。无需解压，也无需太空时代 DLC。安装 DLC 时，科技成本会自动匹配太空时代的重炮。

从 0.1.2 升级时，已有炮台与物品保留。之前开发版默认开放的两个配方会重新受电磁重炮科技控制，需研究新科技。新游戏不再赠送测试炮台和弹药。

兼容性与反馈

已验证原版和完整太空时代加载、研究解锁、真实射击、旧存档升级，以及八门炮同时射击的脚本检查。大型整合包和真实多客户端联机尚未验证。多门炮同时产生等离子与地表效果时，性能取决于硬件与地图规模。

Electromagnetic Siege Cannon

Heavy electromagnetic artillery for Factorio 2.0, with dedicated flying-disc ammunition, synchronized charge and cooling animations, original synthesized sound, and a blue-white plasma blast.

Supports the base game and Space Age. Version 0.1.3 has been tested on Factorio 2.0.77.

Features

• A detailed twin-rail cannon with charge, shot, armor-opening and cooling-fan animation.
• Three-stage rising charge sound, electromagnetic discharge and coolant pressure release.
• Dedicated metal disc projectiles with a blue energy core and fading trail.
• Base range: 336 tiles automatic, 840 tiles manual, 1.5x ordinary artillery. Supports the artillery targeting remote.
• Atomic damage chains scaled by 5x and blast distances by 1.5x; damage reaches approximately 57 tiles.
• Blue-white plasma cloud, expanding shockwave and ground afterglow.
• English and Simplified Chinese localization, new AI-generated icons and matching projectile art.

Research and crafting

Research Artillery → Electromagnetic siege cannon. One new technology unlocks both the cannon and its ammunition. Its science packs, count and time match the final Artillery technology in the active game.

On default Factorio 2.0.77, the base game uses 2000 units at 30 seconds with automation, logistic, chemical, military and utility science. Space Age uses 1500 units at 30 seconds and additionally includes space and metallurgic science. The game research multiplier also applies.

Ammo crafting takes 15 seconds; cannon crafting retains the default 0.5 seconds.

Playing

Research the technology, craft and place the cannon, and load disc ammunition. Use automatic targeting or the artillery targeting remote. A full charge, shot and cooling cycle takes approximately 6 seconds. Ordinary artillery uses ordinary artillery shells; this cannon accepts discs only.

The blast can damage friendly units and buildings. After the blast, corpses, cliffs and paving within its cleanup radius are removed; water, shoreline and landfill foundations are preserved. The effect includes a brief blue-white flash and approximately 35 seconds of ground afterglow.

Installation and upgrades

Put electromagnetic-siege-cannon_0.1.3.zip in your Factorio mods folder and enable it. No extraction or DLC purchase is required. Space Age is optional.

Existing cannons and items survive an upgrade from 0.1.2. Recipes previously enabled by the development build are now gated behind the new technology. Fresh games no longer receive development starter items.

Tested: base game and Space Age, exact research cost matching, recipe unlocks, actual firing, existing-save upgrade, graphical loading and an eight-cannon simultaneous-fire script check. Large overhaul packs and real multi-client multiplayer sessions have not been tested.

Please include your game version, mod version, active mods, reproduction steps and Factorio log in bug reports.
