Grassphobia (beta)

It feels like this one needs a little explanation.

I quite like grass. It's nice, soft and doesn’t get everywhere.
My friend does not like grass. He puts Terrain on Low whenever he can. Why have immersion when you can see enemies, right? And to be perfectly honest that's okay. Everybody has their preferences and one person performing somewhat better than others doesn't change much. If only he didn't host the server...oh

Debug mode of a wonderful addon called LAMBS helps to understand what is the effect that grass has on the AI. Contrary to what you may believe, crawling in grass allows you to sneak, break contact and occasionally stealthly snipe clueless enemies. When the host decides to disable grass for himself, bots are able to see right through it.

The thing is that turning grass off, can make some sense. In ARMA, once you fire a couple of shots, the AI will know your exact position no matter how much grass there is in the way. They will also track your position for the next 3 or more seconds after breaking line of sight. That’s why fighting uphill at close range may often feel unfair. Now multiply that by what happens on ours group server and you get why this addon exists.


Grassphobia is a highly customizable addon that lets you reduce grass in a desired area.
Pressing a keybind (SHIFT + C by default) places vanilla ClutterCutter objects on a fake-hexagonal grid around the player. Using CBA Settings you may change the following parameters:

- Size
ClutterCutter object to be used by the script.
- Pattern
Cutter placement pattern based on filling parts of a hexagon. See screenshots for reference.
- Range
Distance from player to be filled with cutters.
- Radius
Spacing between cutters. Used to leave patches of grass or remove it completely.
- Line thickness
Width of Line pattern measured with cutters.
- Burst length
Number of cutters to be spawned at once. Used to avoid stutters when spawning a large amount of objects.
- Burst delay
Delay between bursts.
- Enable global execution
Cutters generate for all clients.

Placing a new set of cutters removes the previous one. (see known issues below)

1. Preset system
System for saving multiple ways of cutting grass with keybinds to cycle/switch between them.
2. Random cutter offset
Slider for subtle randomized offset in placement of cutter objects for a less grid-like appearance.
3. Debug/visualisation tool
3D circles/hexes visualising placement and ranges of cutter objects coupled with additional debug log.
4. Better/nicer/prettier code
5. Fancy showcase
Video showcasing all of the features and settings once the mod is done.
6. (to be researched if it’s even possible) option to flatten grass instead of removing it


- Grassphobia can occasionally give an "index out of bounds/zero divisor" error. It does not break anything and will be fixed in future releases.
- Removed grass does not always comeback after placing a new set of cutters. I currently assume it is hardcoded and cannot be fixed.
- Certain combinations of Radius and Pattern settings result in a line of grass patches being placed directly in front of players vision. I hope to fix it with Random cutter offset in a future release.

1. I've never wrote an addon before Grassphobia. Despite being quite happy with the current code, it’s structure and optimization, I’m fully expecting for something to be missing or broken. Please consider reporting your findings.
2. LAMBS Debug Draw mode is a great tool for understanding how the AI sees in ARMA. I highly recommend it.
3. Beketov’s forests are unplayable with grass enabled and plain ugly without it. I've heard that they are lovely this time of the year.
