Doodle up a shared summonable whiteboard with mspaint tools

About this mod Author’s original text

bwpaint

You put a board in the world. You walk up to it. You press E. The camera politely stops moving and a mouse cursor appears, and you may now draw whatever you like on it. A pencil, a bucket, an ellipse, a sad little line.

Think mspaint or the whiteboard in Duke Nukem Forever, but you are standing in a field and the canvas is a rectangle.

But how?

  • Install BepInEx 6 (IL2CPP build) for Big Walk and run the game once.
  • Drop the mod folder into BepInEx/plugins.
  • Start the game. Press F10. A board appears about two and a half meters in front of you, standing on the actual ground.
  • Look at it, get within about 3.5 meters, press E.
  • Draw.

But what do the buttons do?

Outside of draw mode there are only three things to know.

| Key | Action |

| --- | --- |

| F10 | Place the board in front of you, or pick it up again. Your drawing is kept while it's picked up. |

| E | While aimed at the front of the board: enter draw mode. While in draw mode: leave it. |

| F11 | Save a png copy of the current board image in a Whiteboard folder. Works any time the board is placed. The frame flashes green so you know it did something.

Find saved pngs in BepInEx/Whiteboards, named whiteboard_ followed by the date and time. It defaults to 1280 x 640 on a white background. The info pad also tells you the full path when it saves.

Everything else only works in draw mode, so none of it steals keys from the game while you're out walking.

In draw mode

Your camera locks, your movement locks, your cursor comes back. Left mouse draws. An info pad shows up at the top of the screen telling you your tool, colour, brush size and so on.

| Key / Input | Action |

| --- | --- |

| Left mouse | Draw with the current tool |

| Right mouse | While dragging a shape: cancel it |

| 1 | Pencil |

| 2 | Eraser (three times the size of your brush, because erasing is bigger than drawing) |

| 3 | Line |

| 4 | Rectangle |

| 5 | Ellipse |

| 6 | Fill bucket |

| 7 | Colour picker. Click anything on the board to change over its colour, then it hands you back your previous tool. |

| F | Shapes: outline or filled |

| C / V | Previous / next colour (12 of them) |

| [ / ] | Smaller / bigger brush |

| + / - | Make the board bigger / smaller. Hold it down. Keypad works too. |

| U | Undo the last stroke |

| Delete | Wipe the whole board |

| E | Leave draw mode |

Switching tools, undoing and wiping are ignored while you're holding the mouse button down mid-stroke.

The shapes show a live preview while you drag, so you can change your mind before letting go. Right-click if you really regret it.

But the board is too small

Hold + or - in draw mode. It goes from half size to four times size, and the bottom edge stays where it was so it doesn't sink into the grass or float away.

Note that resizing changes how big the board is in the world, not how many pixels it has. Make it huge and your pixels get chunky. Make it tiny and you've made a postage stamp.

But can everyone see it?

Yes, if everyone has the mod. There is one shared board per lobby. When someone places it, everyone sees it. When someone draws on it, everyone watches the lines appear.

The rule is one artist at a time. Whoever presses E first holds the pen, and everyone else sees "Someone else is drawing" until they step away (E again) or leave. No fights over the undo button, no two people filling the same circle with different colours. If the artist vanishes mid-masterpiece, the pen frees itself after a few seconds.

Anyone can pick the board up (F10) or move it, as long as nobody is drawing. Picking it up hides it for everyone. Placing it brings it back, wherever you stand. Drawings stay on it in between.

If you join late, the host sends you the board as it currently looks, so you don't miss the first half of the doodle. You just can't undo strokes from before you arrived.

Everybody in the lobby needs the mod. The sharing works by sending the game's networking some messages it has never heard of. A host without

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
