miaoda-game-vision-cocos

Use this Cocos Creator adapter to draw continuous visibility polygons/cones with Graphics and to bridge simple line-of-sight checks to Cocos PhysicsSystem2D.raycast.

Install and use

pnpm add miaoda-game-vision2d-core miaoda-game-vision-cocos

Cocos Creator provides the optional cc peer dependency at runtime.

import { VisionLayer } from 'miaoda-game-vision-cocos';

const layer = lightRoot.addComponent(VisionLayer).setup({
  fillColor: { r: 255, g: 240, b: 180, a: 90 },
});
layer.obstacles.addBounds({ minX: 0, minY: 0, maxX: 960, maxY: 640 });
layer.obstacles.addRect({ minX: 400, minY: 300, maxX: 460, maxY: 360 });

layer.renderCone(guardPos, facingDeg, 70, 400);
if (layer.inView(guardPos, facingDeg, 70, playerPos, 400)) raiseAlarm();

Call renderFrom or renderCone from your game loop; the layer does not auto-tick. Add bounds before rendering to close the ring. physicsLineOfSight is for collider-backed clear/blocked checks only; visibility polygons still use the core obstacle geometry.
