💖 NUMPTYPHYSICS 💖

okay bestie, so this is the manual for numptyphysics — that's section 6 of the manual, the games one — and it's giving Crayon-based physics puzzle game. yeah. crayons. physics. chaos. let's go 🖍️✨

🌈 SYNOPSIS 🌈

numptyphysics

that's it. that's the whole synopsis. no flags, no args, just vibes and launch it 💅

---

🎀 DESCRIPTION 🎀

Numpty Physics is a Crayon-drawing puzzle game in the spirit of Crayon Physics, and it runs on the same excellent Box2D engine. it melds cute schoolbook-style graphics with a kind of realistic physics engine. yes, those two things CAN coexist, and they ate. 🔥

and the best part?? it has a built-in editor so you may build (and submit) your own levels. main character energy fr fr 👑

a summary of the keys supported is included below. yes we're getting to it, be patient 🫶

🕹️ PLAY KEYS 🕹️

• stylus — draw a new stroke ✏️
• space or enter — pause/unpause physics ⏸️
• esc or backspace — undo last stroke 😭 (we've all been there)
• q — quit 🚪
• r or up — reset level to initial state 🔄
• n or right — skip to next level ⏭️
• p or left — go to previous level ⏮️
• e or fullscreen — edit mode 🛠️

✨ Hints ✨

each stroke is like a rigid piece of wire with a mass proportional to its length. so like. longer wire = heavier. physics said so. a closed stroke is just a wire bent into a shape — it has no substance apart from its perimeter. hollow little guy 🫥

the ends of strokes can (and will) join onto other strokes when drawn near enough to another stroke. and these joints are pivots, so you can use this to build levers, pendulums and other mechanical wonders. engineer era unlocked 🧚✨

jointed strokes don't collide with each other. join both ends to make a rigid structure.

🐛 Play bugs: goal item does not respawn if lost. yeah. if you lose it, it's gone gone. 💀

✏️ EDITOR KEYS ✏️

keys are as per play mode, plus the following:

• e or fullscreen — leave edit mode 🚪
• s or menu — save to ~/.numptyphysics/L99_saved.nph 💾
• zoom-minus + stylus — delete stroke at point 🗑️
• zoom-plus + stylus — drag stroke at point 🫳

🌸 Hints 🌸

it's handy to pause the physics when making a new level, though this is by no means necessary. sometimes it is handy to let the physics run for a little bit just to let the items settle down. let them chill. let them breathe 🧘

from the editor palette you can choose the crayon colour and then additional properties such as:

• ground (earth arrow) — stroke is fixed in place 🧱
• sleeping (Zzz) — stroke is not subject to physics until bumped by something else 😴
• decorator (dashed D) — stroke is not part of the physical world. eg: tutorial text 🎀

you should make sure that your level has at least one red item (player token) and at least one yellow item (goal item). no red, no player. no yellow, no goal. rules are rules 💅

token strokes will only join to other token strokes. goal strokes will only join to goal strokes. other strokes will happily join to any non-token non-goal strokes. they're the friendly ones 🫶

if this is your first time, you may need to restart the game for your saved L99 to show up. yeah, classic. 🙈

if you wish to be clever, edit the level file directly — it's just a simple text format. hacker girl summer 💻✨

🐛 Editor bugs: there is not yet any provision to name your level, but you can just rename the file to anything. problem solved, iconic behaviour 👑
