Advanced Radar Scanner / 高级雷达扫描器

Advanced Radar Scanner is an optional client-side Risk of Rain 2 mod. Whenever any player activates the vanilla Radar Scanner, clients with this mod replace selected interactable markers and may locally hide player-marked interactables. Players without the mod keep all original markers and can remain in the same lobby.

高级雷达扫描器是一个可选客户端 Mod。联网中的任意玩家使用原版雷达扫描器后，安装本 Mod 的客户端会替换指定可交互物的图标，并可在本地隐藏玩家标记的物体。未安装的玩家继续显示全部原版图标，双方仍可加入同一个房间。

Features / 功能

• Preserves the vanilla equipment, cooldown, radius, target selection, reveal duration, and networking.
• Does not add network messages, network prefabs, items, or equipment.
• Uses [NetworkCompatibility(CompatibilityLevel.NoNeedForSync)]; the host and other clients do not need the mod.
• Generates the in-game marker sprites locally at runtime, so no AssetBundle is required.
• Changes five marker types: Legendary Chest, Multishop, Item Scrapper, Equipment Barrel, and Void Cradle.
• Aim at an interactable and press F to toggle whether its future scanner marker is hidden locally.
• Keeps every other scanner marker unchanged.

当前新增图标：

• 传奇箱：箱子与星形
• 多选商店：三个并列货位
• 物品回收机：投入物品、向下箭头与粉碎齿口
• 装备桶：圆柱桶身与闪电符号
• 虚空摇篮：托架、裂口与虚空核心

准星对准当前可交互物时按 F，可切换是否在后续雷达扫描中隐藏它。此状态仅存在于本机，并在物体销毁或换关后自动清除。

Multiplayer behavior / 联机行为

The mod reacts to the vanilla ChestRevealer.RevealedObject marker on each client. It does not need to know which player activated the scan.

BepInEx/config/com.nolan.AdvancedRadarScanner.cfg

Available groups:

Use r2modman/Thunderstore Mod Manager, or copy AdvancedRadarScanner.dll into:

BepInEx/plugins/AdvancedRadarScanner/

Building / 构建

Requirements: .NET 8 SDK or newer.

dotnet restore AdvancedRadarScanner.sln

The release DLL targets .NET Standard 2.1 and currently compiles against RiskOfRain2.GameLibs 1.4.1-r.0.

Compatibility notes

This mod only changes existing scanner marker renderers. A game update or another UI mod may change the marker prefab hierarchy; enable LogClassifications when diagnosing an icon that remains vanilla.

Changelog

0.3.17

• Apply the custom scanner icon before hiding a newly revealed target. Restoring it with F during the same scan now shows the custom icon instead of the vanilla icon.

0.3.16

• Fixed F restoration by preserving each renderer's original enabled state during overlapping child and parent traversal. Removed the unnecessary manual RevealObject call; vanilla scans already refresh existing marker lifetimes.

0.3.15

• Attempted to re-enter restored targets through the vanilla RevealedObject.RevealObject path. This did not correct the renderer state issue and was superseded in 0.3.16.

0.3.14

• Restored an ignored marker immediately when it is re-enabled with F. It keeps the current Radar Scanner pulse expiry and disappears together with the other markers.

0.3.13

• Restored a re-enabled marker immediately after the next real Radar Scanner pulse, including when the previous scan's other markers are still active.

0.3.12

• Fixed restoration during an active scan by tracking the active marker hierarchy, allowing a restored target to participate in another scan before the original ten-second window ends.

0.3.11

• Fixed a follow-up scan issue after immediate hide-and-restore: local ignore state now changes synchronously instead of waiting for component destruction.

0.3.10

• Replaced the feathered marker outline with a single, fixed-opacity black border to match vanilla icon edges.

0.3.9

• Reduced the opacity of the wide marker outline and its outer feather to better match the softer vanilla chest border.

0.3.8

• Refined immediate marker recovery: only markers still active during the current scan reappear; restoring an ignored target outside a scan only affects future scans.

0.3.7

• Fixed the F toggle so active Radar Scanner markers hide or reappear immediately instead of waiting for the next scan.

0.3.6

• Doubled the exterior black border to a four-pixel core with a two-pixel transparent outer edge, while retaining slimmer outlines for enclosed cutout details.

0.3.5

• Thickened every custom marker outline to a two-pixel deep black border with a one-pixel transparent outer edge, matching the vanilla chest marker more closely.

0.3.4

• Added a two-pixel transparent black outline to every custom marker, including its inner cutouts, to match the contrast of vanilla Radar Scanner icons.

0.3.3

• Simplified the Item Scrapper marker into a solid machine body with hollow arrow and shredder details.
• Added a wireless Radar Scanner marker based on the approved signal-arc silhouette.
• Added a crescent-moon marker for Lunar interactables.

0.3.2

• Refined the Item Scrapper marker into a solid square machine body with a separated item cartridge and transparent cutout details.

0.3.1

• Redesigned every custom scanner marker with solid silhouettes and transparent cutout details to better match the vanilla marker style.

0.3.0

• Added opt-in, host-coordinated sharing for ignored Radar Scanner markers.
• The host now sends shared ignore state only to clients that have this mod enabled.
• Added late-join synchronization and automatic state reset at the start of each stage.

0.2.0

• Made the three-terminal Multishop icon solid.
• Added redesigned Equipment Barrel and unique Void Cradle icons.
• Added a configurable F shortcut to toggle local Radar Scanner visibility for the currently selected interactable.
• Preserved each vanilla marker's world-space size when replacing its sprite.

0.1.0

• Initial client-side release.
• Added runtime-generated scanner icons for Legendary Chests, Multishops, and Item Scrappers.
• Redesigned the Item Scrapper icon as an item entering a toothed shredding machine.
• All other Radar Scanner icons remain vanilla.
• Added optional-client multiplayer compatibility declaration.
• Added per-category configuration and diagnostic classification logging.
