StarCraft Minimap Radar

Demo video

See the minimap pixel radar in action — a quick look at how it tracks enemy movement in a real game.

Tired of missing the minimap?

Your hands are building up the base, your eyes are stuck on a fight, and meanwhile a single enemy scout slips in along the yellow path and slips back out. You already know where the next harass is coming.

StarCraft Minimap Radar watches only the red pixels (= enemy) on the minimap. The moment a new movement appears, it pops up in the status window, and the instant red crosses into your main-base zone, it triggers a system sound and a red pulse warning.

It never touches game memory or D3D. It only captures and analyzes your own screen, so there is no EULA risk — same safety profile as OBS screen sharing.

Step 1 (required) — Switch SC:R to “Windowed [Fullscreen]”

The overlay needs to float on top of the game, so it does not work in true Fullscreen mode. In-game, go to Options → Video → Display Mode and select Windowed [Fullscreen].

Step 2 — Download and run

Use the download button above or grab StarCraftMinimapRadar-0.5.1-portable-x64.zip from the release repository. Just unzip — no installer, the .NET runtime is bundled into the exe.

A control panel opens on launch:

Three steps to be ready:

1. 🖱 Pick on screen (Ctrl+Alt+M) — with the game visible, click this, drag a box over the minimap, press Enter, and the coordinates are captured.
2. 🖱 Pick main base (Ctrl+Alt+B) — drag a box over your starting base inside the minimap. Enemies entering this box trigger the base alarm.
3. Once coordinates are set, monitoring turns on automatically — no need to re-toggle every session.

Step 3 — Park the status window next to the game

The status window is a click-through overlay — mouse and keyboard input pass through to the game.

Always visible in the status window:

• Minimap ON/OFF — monitoring state
• Base ON/OFF — base alarm state
• Enemy pixels: NN — total red pixels right now (jumps when new enemies appear)
• Six hotkeys at the bottom — no need to memorize, always visible

To reposition: press Ctrl+Alt+E to enter move mode, drag, press again to lock.

Scenario 1 — Catching the early scout

Two minutes in, the opponent's scout enters along the yellow path while you're busy with gas in your main...

The overlay detects the newly appearing red pixel on the minimap and shows ⚠ Minimap enemy movement (+N px) in the status window. A dashed orangetracking rectangle over your screen's minimap shows what region is being watched.

Sensitivity: Control panel → “Common settings” → Movement threshold combo

• Very sensitive (2 px) — catches a single scout
• Standard (4 px) ← recommended
• Squads only (10 px) — alerts only on larger groups

Scenario 2 — Enemy just crossed the base line!

The base alarm is not a simple “enemy detected.” It fires once on entry into the base zone, and only fires again after the enemy leaves and re-enters (hysteresis). No spammy repeat alarms from units sitting in place.

When the line is crossed:

• System sound Exclamation plays
• Large red text in the status window: 🚨 Enemy crossed the base line! (N px)
• The base zone on your game screen pulses red

No more “wait, harass arrived already?” moments while building gas.

Scenario 3 — Multi-base harass under simultaneous pressure

Mid-game: harass on your expansion plus pressure on your main at the same time. Reds pop up all over the minimap. The overlay clusters each location and groups the alerts, and the bottom of the status window stacks the latest 6 alerts.

Tune detection sensitivity (Common settings → Detection sensitivity combo) to balance ignoring debris flicker vs catching even single pixels:

• Sensitive — allows some debris flicker (don't miss anything)
• Standard ← recommended
• Conservative — strong filtering of static patterns (fewer false positives)

Hotkeys at a glance

Designed so you can toggle alarms or re-pick regions in-game without ever leaving the keyboard.

⚠ Important note

Most 1v1 ladder games assign player 1 to a non-red slot so this is rarely an issue, but watch for it in campaign or custom games.
