What if a farming game didn’t let you click anything?
What if the only way to control the world… was to write C++?
I built exactly that.
A browser-based game where you control a farming drone entirely through C++ code — compiled to WebAssembly and executed live in the game.

No install.
No setup.
Just open and start coding.
You Don’t Play. You Program.
The world is a grid.
Each cell can be:
- Empty
- Tilled
- Planted
- Growing
- Ready to harvest
- Base station
The drone can:
- Move across the grid
- Till soil
- Plant different crops
- Water them
- Harvest them
- Buy seeds
- Manage energy and water
- Earn gold
- Increase score
But here’s the key difference:
You never click to move.
You never press a harvest button.
You write the logic — and the drone executes it.
It Quickly Stops Being “Farming”
At first, it feels simple:
If a cell is empty — plant.
If it’s ready — harvest.
But then systems start stacking:
- Water tank capacity
- Energy limits
- Seeds cost gold
- Crops grow over time
- Grid traversal must be efficient
- Score depends on smart decisions
Suddenly, it’s not a farming game.
It’s an optimization problem.
It’s About Designing Behavior
You don’t react.
You design.
You write loops.
You define conditions.
You structure traversal.
You manage resources.
If your logic is inefficient:
- You waste ticks
- You waste energy
- You miss harvest windows
- Your score drops
The game becomes about algorithm design.
Why C++?
Most programming games use Python.
I deliberately chose C++.
Because C++ forces clarity:
- Strong typing
- Explicit control flow
- Deterministic execution
- Clear system boundaries
It feels less like scripting.
More like engineering a machine.
And your drone is that machine.
Under the Hood
- Your C++ code is compiled to WebAssembly
- A restricted drone API is injected
- The simulation runs in a sandbox
- Grid size is provided dynamically
- Only safe functions are exposed
Your code becomes the AI brain.
The game becomes the environment.
Clean separation.
Deterministic simulation.
Pure logic.
Where This Can Go
This is just the first version.
But the concept has serious room to grow:
- Competitive bot leaderboards
- Optimization tournaments
- Different maps with obstacles
- Energy-constrained challenges
- Multi-drone simulations
- Profit-maximizing strategies
- Time-based scoring competitions
It could evolve into a full C++ automation strategy game.
Or even a competitive AI arena in the browser.
Try It
If you enjoy:
- Automation

This started as a small experiment.
But “control a drone with C++” feels like a concept with real potential.
