# Gravity Shift: Low-Poly Physics Platformer

A prompt that lays out the concept and the technical brief for a 3D puzzle-platformer where the whole world turns 90 degrees on a keypress. Useful as a starting skeleton for a Three.js and Cannon.js build.

## What it does

The prompt sets up Gravity Shift: a cube-shaped maze in low-poly style, pastel gradients, sharp geometric shapes. The player never climbs walls — they rotate the world's gravity and change where down is.

The technical half asks for a 3D platformer on Three.js and Cannon.js, with `R` rotating the `world.gravity` vector by 90 degrees. A short JavaScript snippet shows the rotation: the new vector is derived from the current one and copied back into `world.gravity`. Smooth camera interpolation with Lerp is called out so the camera follows the player's rigid body during a shift.

This is a conversation starter, not finished code. It hands the model a brief and one piece of logic; the rest you write yourself. The rotation angle in the example is fixed at 90 degrees, and no other angle appears.

## When to use it
- sketch out a 3D platformer on Three.js and Cannon.js
- rotate world gravity 90 degrees on a keypress
- build a cube-shaped maze in low-poly style
- keep the camera on the player's body during a gravity shift
- write down a game concept before starting the build

## Example prompts
- Build the Gravity Shift 3D platformer with Three.js and Cannon.js: a cube maze where pressing R rotates world.gravity by 90 degrees
- Add smooth Lerp camera interpolation so the camera follows the player's rigid body when gravity shifts
- Give the level a low-poly look with pastel gradients and sharp geometric shapes

BEGIN THIRD-PARTY FILE fd5a9869381b3b81
```text
Game Concept: A puzzle-platformer named "Gravity Shift" where players rotate the entire world to navigate a 3D low-poly labyrinth. The environment is minimalist, using pastel gradients and sharp geometric shapes.
Technical Prompt:
Build a 3D platformer using Three.js and Cannon.js. The world is a cube-shaped maze. When the user presses 'R', rotate the world.gravity vector by 90 degrees.

JavaScript
// Gravity rotation logic
world.gravity.set(0, -9.82, 0); // Default
function rotateGravity() {
  let newG = new CANNON.Vec3(-world.gravity.y, world.gravity.x, 0);
  world.gravity.copy(newG);
}
Include smooth camera interpolation using Lerp to follow the player's rigid body during shifts.
