Casazium Tank Command

Six tanks, four targets and a battlefield that is different every time you press F5. A real-time-strategy prototype built in Godot, free to download for macOS, Windows and Linux.

Download the prototype What it is

Free, no account, no telemetry. The builds are unsigned, so macOS and Windows will block the first launch — here is how to get past that.

Six pale green-ringed tanks sit in two rows on a grassy hillside while four red enemy tanks wait on the ridge above them, boulders scattered across the slope between.

What this is

A prototype of the parts of a real-time-strategy game that are hard to fake: terrain that generates itself, units that find their own way across it, and gunnery that solves for a firing solution instead of pretending to. You get six tanks on a 128-metre battlefield, four enemy tanks to shoot at, and a new map whenever you want one. It was built to find out whether those pieces could be made to work together, and they can.

It is not a game. There is no AI — the enemy tanks sit still and take it. There is no sound, no menu, no score, no campaign, and no way to win or lose. Nothing is saved between runs. Treat it as something interesting to drive around for ten minutes, not as something to finish.

Screenshots

All six tanks fire at once: muzzle flashes light the grass yellow around them and shells climb away from the barrels toward the ridge. — A six-tank volley. Each barrel elevates to its own computed launch angle before firing, so tanks at different ranges from the target point sit at visibly different elevations in the same salvo.

Overhead view of the six tanks holding a two-by-three formation on open grass, each ringed in green to show it is selected, with boulders scattered around them. — The whole group selected, seen from above. The debug readout across the top carries the map seed — `20260917` here — which is the number the entire battlefield was generated from.

How it works

Every map comes from a seed: Terrain, boulder placement and the pathfinding grid all derive from one number, displayed on screen while you play. A map is therefore reproducible from its own screenshot. Press F5 for another.
Pathfinding is a grid A*, not a navigation mesh: Godot 4.7.2's navmesh baker returns zero polygons for every input here, verified down to a bare flat quad, so a navmesh was never an option. The grid turned out to be the better fit anyway: the terrain is already one.
Tanks steer around each other: They collide with one another and with boulders, and adjust course to avoid both. Avoidance is advisory rather than absolute: when it is the thing preventing an order from completing, it fades out and lets the unit reach its position.
Gunnery is solved, not faked: Barrels elevate to a computed launch angle and shells arc under gravity rather than travelling in a straight line to a guaranteed hit. A shell aimed at a point 49 metres away lands 1.4 metres from it.
The models are Blender, exported as glTF: The tank and the scattered rocks were modelled in Blender and brought in as glTF. Everything else on screen — the terrain surface, the selection rings, the shells — is generated at runtime.

Controls

Input	Does
Left-drag	Select units with a box
Left-click	Select one unit; hold Shift to add or remove
Right-click	Move there — the group spreads into a formation
F	Fire (about 2 seconds to reload)
X	Stop
W A S D / arrows	Pan the camera
Q / E	Rotate
Mouse wheel	Zoom
Middle-drag	Grab the ground and drag it
F5	Generate a new map
F2	Toggle edge scrolling
Cmd-Q / Alt-F4	Quit — there is no menu to quit from

Edge scrolling is off by default. With it on (F2), moving the mouse near an edge of the screen pans the camera that way. Nothing is drawn on screen either way — it only changes how the camera moves.

Verify a download before running it: shasum -a 256 CasaziumTankCommand-macOS.zip on macOS or Linux, certutil -hashfile CasaziumTankCommand-Windows.zip SHA256 on Windows. The authoritative list is SHA256SUMS.txt. For an unsigned build this is the only integrity check you have.

Your computer will block this on first launch

Both desktop builds are unsigned. That is not a sign of anything wrong with the file: code-signing certificates cost money per year, and this is a free prototype, so none was bought. Your operating system cannot tell the difference between "unsigned" and "unknown", so it stops the app and warns you. Here is how to get past it.

macOS

You will see “CasaziumTankCommand” cannot be opened because the developer cannot be verified. Right-click the app, choose Open, then click Open in the dialog that follows. You only have to do this once. From a terminal, this does the same thing:

xattr -cr /path/to/TankRTS.app

Windows

SmartScreen shows “Windows protected your PC.” Click More info, then Run anyway. The warning names the publisher as unknown, which is exactly what an unsigned build is.

Known limits

The enemy tanks do not move, aim or fire. They are targets.
There is no sound at all.
There is no menu, no pause, no score, and no way to win or lose.
Nothing is saved. Every launch starts over with a new map.
Quit with Cmd-Q, Alt-F4, or by closing the window.
Both desktop builds are unsigned — see above.
