I'm trying to triangulate a convex polygon.

On the left are the triangulated polygons, while on the right is the convex polygon without triangulation. (both are wrong) but the one on the right is in the correct position and besides the fact that it's missing the convex part, it's pretty ok...

I create the triangles and add them to an arraylist

float[] vertices = polygonObject.getPolygon().getTransformedVertices(); float[] worldVertices = new float[vertices.length]; for (int i = 0; i < vertices.length; ++i) { System.out.println(vertices[i]); worldVertices[i] = vertices[i] / ppt; } // Make triangles Vector<float[]> trianglesVertices = new Vector<float[]>(); EarClippingTriangulator triangulator = new EarClippingTriangulator(); ArrayList<PolygonShape> triangles = new ArrayList<PolygonShape>(); ShortArray pointsCoords = triangulator.computeTriangles(worldVertices); for (int i = 0; i < pointsCoords.size / 6; i++) { trianglesVertices.add(new float[] { pointsCoords.get(i*6), pointsCoords.get(i*6 + 1), pointsCoords.get(i*6 + 2), pointsCoords.get(i*6 + 3), pointsCoords.get(i*6 + 4), pointsCoords.get(i*6 + 5), }); PolygonShape triangleShape = new PolygonShape(); triangleShape.set(trianglesVertices.get(i)); triangles.add(triangleShape); }

later I loop that arraylist and create bodies, but somehow libgdx(probably me, not libgdx) totally messes it up.

for(PolygonShape triangle:triangles){ BodyDef bd = new BodyDef(); bd.type = BodyDef.BodyType.StaticBody; Body body = world.createBody(bd); body.createFixture(triangle, 1); bodies.add(body); triangle.dispose(); }

Here is the shape I am trying to render in libgdx (created in Tiled)
