绘制墙壁时使夹具（形状）透明

Question

从示例中使用的createBoundaries，我了解了如何创建“墙”/EdgeShape。

移动相机时，我会画线。杜你知道如何不画这些线或使它们透明 - 看过FixtureDef？

import 'package:flame_forge2d/flame_forge2d.dart';

class Wall extends BodyComponent {
  final Vector2 start;
  final Vector2 end;

  Wall(this.start, this.end);

  @override
  Body createBody() {
    final shape = EdgeShape()..set(start, end);

    final fixtureDef = FixtureDef(shape)
      ..restitution = 0.0
      ..friction = 0.3;

    final bodyDef = BodyDef()
      ..userData = this // To be able to determine object in collision
      ..position = Vector2.zero()
      ..type = BodyType.static;

    return world.createBody(bodyDef)..createFixture(fixtureDef);
  }
}

Answer 1

在这种情况下，将renderBody = false 设置为renderBody = false 或覆盖render 为空，Wall。
