WarEra Diplomacy OS v3.2 – The Battle heatmap & Sphere of influence!
WarEra Diplomacy OS v3.2 – The Battle heatmap & Sphere of influence!
By https://app.warera.io/user/69d2ed249f38d300d59a2af1 – your local tool maker
First of all, I want to give a massive shoutout to everyone who's been using the tool and sending feedback. Your ideas and bug reports are what keep this project alive. This update is packed with features you've been asking for – and a few surprises I've been cooking up in the background.
Now, let's dive in.
Hello everyone! Just a few weeks after the alliance update, I'm back with another major release for the diplomacy tool. This time, I've focused on two things you've been requesting for a while: real-time battle intelligence and deeper diplomatic relations.
Let's call this v3.2 – and it's a big one.
⚔️ Active Battles – Live on the Map
This is the feature I'm most excited about. Battles are now visible directly on the map as interactive markers that update in real time.
How it works:
Every active battle appears as a compact, information-rich marker on the map
Each marker shows:
Attacker vs Defender with their flags and names
A damage progress bar showing who's winning
The region name where the battle is taking place
A 🔴 Live badge when real-time data is available
The marker adapts to your zoom level – it shows more detail when you zoom in and stays clean and readable when zoomed out. Hover over any marker to see it glow, and click it to reveal a detailed tooltip with exact damage numbers and percentages.
But the real magic happens when you click a battle marker...
Behold – the Battle Heatmap.
🌡️ Battle Heatmap – See Who's Really Fighting
Click any battle marker and the entire map transforms. Every nation involved in the battle is color-coded based on their contribution.
Attacker nations glow in shades of blue – the darker the blue, the more damage they've dealt
Defender nations glow in shades of red – same logic, the darker the red, the harder they're fighting
Each nation's label shows the percentage of damage they contributed to their side – so you can instantly spot who's carrying the war effort and who's just along for the ride.
The heatmap updates live every 10 seconds – you can watch the battle evolve in real time. And the nation tooltip now shows battle-specific stats when you're in heatmap mode: side (attacker/defender), rank, total damage, and share of the side's total damage.
Exit the heatmap by pressing ESC, clicking the "Exit Heatmap" button in the legend, or clicking anywhere on the map outside a battle marker.
It's like having a live war room overlay on your map.
🎯 Sphere of Influence – Proxy Networks Visualized
WarEra politics aren't just about alliances – they're also about who controls whom. The new Sphere of Influence mode shows you which nations are acting as proxies for major powers.
How it works:
A CSV file (
SphereOfInfluence.csv) defines which nations are "primary" and which are "proxy"All nations under the same primary share the same color – so you can see spheres of influence at a glance
The legend shows each sphere with the primary nation's name and the number of proxy nations
⚠️ Important note: This data is community-maintained. Every WarEra player knows that proxies exist in the game, but the exact relationships can be complex and sometimes unclear. The CSV isn't complete – it's a living document that depends on player knowledge and observation.
That's where you come in! If you know of proxy relationships that aren't represented, or spot an error in the current data, please reach out or contribute to the CSV. The more accurate this becomes, the more useful the Sphere mode will be for everyone.
Special thanks to everyone who's already helped map the proxy networks – your contributions make this feature possible.
This is perfect for understanding the true balance of power behind the scenes. Who's really running the show? The Sphere mode will show you.
🎨 New UI Layout – Two Rows of Modes
With all these new visualization modes, the old single row of buttons was getting cramped. I've reorganized the UI into two rows:
Row 1 (3 buttons):
⚔️ Diplomacy – all your diplomatic relations (allies, wars, NAPs, defensive pacts, sworn enemies)
🏛️ Blocs – alliance coloring with bloc labels
🎯 Sphere – sphere of influence visualization
Row 2 (2 buttons):
🔥 Weekly Dmg – damage heatmap
👥 Pop. – population density heatmap
The sliders move independently – when you select a mode from the first row, the second row's slider fades slightly (and vice versa). It's cleaner, more intuitive, and gives each mode the space it deserves.
🖥️ Smarter Battle Markers – Zoom-Adaptive & Resilient
The battle markers aren't just pretty – they're smart.
Zoom-adaptive: At zoom level 3.5+, you see full nation names and damage bars. At lower zoom, they compress to show just the essentials (region name, flags, percentages)
Resilient to rate limits: If the API hits a 429 (too many requests), the tool shows a dedicated rate limit tooltip and falls back to cached data – so you never lose the map
Live updates every 30 seconds: Battles refresh automatically, keeping you up to date without manual reloading
🔮 What's Next – The Road to v4.0
With v3.2 out, I'm already planning the next steps:
📈 New & More Precise Statistics
Damage per capita and damage efficiency (weekly damage / development)
More heatmap variants
🧮 Alliance Calculations & Bonuses
Surface alliance-wide bonuses, development metrics, and more inside the Bloc Statistics page.
🗺️ Diplomacy Timeline
A feature I've been dreaming about – replay how alliances and wars evolved over time.
If you have ideas or want to see something specific, drop me a message. The map is for the community – I just build it.
🌐 Reminder – The Chrome Extension
The WarEra Diplomatic Mode extension has been on the Chrome Web Store for a while, and it works perfectly with v3.2. If you haven't tried it yet, now is a great time.
With one click, the extension overlays the entire Diplomatic OS directly onto the official WarEra map interface – no tab-switching. It brings:
Geopolitical heatmaps (allies, wars, borderline nations)
Extended diplomacy logic (friends of friends, enemies of allies)
Manual NAP priority
High-contrast borders, coastlines, and official flags
The same live battle markers and heatmaps
Once installed, a "Diplomatic OS" button appears right on the game map. One click, and the world redraws itself with tactical clarity.
☕ Support the Work
If these updates help you navigate the chaos of WarEra politics, consider buying me a coffee. Every cup keeps the features coming – and helps me justify the late nights spent coding instead of sleeping.
