I use matter.js physic engine for my game. I updated body vertices with call setVertices but after call his collisions are not updated, so other object does not fall. Maybe I skipped some basic principles of using matter.js so I present short version of using them, if this is not enough I will create a separate working example.
// Init engine
const engine = Engine.create();
const runner = Runner.create();
Runner.run(runner, engine);
// Add circle for check collision
const circle = Bodies.polygon(300, 100, 5, 12, {
frictionAir: 0, friction: 0.0001, restitution: 0.6
});
World.add(engine.world, circle);
// Create a body from vertex (parsed from svg path)
// Original vertexes
const mapVertexes = [[..]];
const ground = Bodies.fromVertices(400, 400, mapVertexes, { isStatic: true }, true);
World.add(engine.world, ground);
// On click to update vertices for polygon
const newVertices = [...]
Body.setVertices(ground, newVertices);
Before update vertices:
After update vertices:
