Question

我想分裂，我一直收到这个错误？

gradle错误;不相容的类型;可能有损转换从double到float？

protected World world;
protected TiledMap map;
protected TiledMapTile tile;
protected Rectangle bounds;
protected Body body;

public InteractiveTileObject(World world, TiledMap map, Rectangle bounds ){
    this.world = world;
    this.map = map;
    this.bounds =  bounds;

    BodyDef bdef = new BodyDef();
    FixtureDef fdef = new FixtureDef();
    PolygonShape shape = new PolygonShape();

    bdef.type = BodyDef.BodyType.StaticBody;
    bdef.position.set((bounds.getX() + bounds.getWidth()/2)/MyGdxGame.PPM, (bounds.getY() + (bounds.getHeight() / 2)) / MyGdxGame.PPM);

    body = world.createBody(bdef);

    shape.setAsBox(bounds.getWidth()/2 /MyGdxGame.PPM, bounds.getHeight()/2 /MyGdxGame.PPM);
    fdef.shape = shape;
    body.createFixture(fdef);
}

Answer 1

如果您正在调用接受float的方法，但是传递的是double，则必须将double显式转换为float。您可以通过将(float)放在每个参数前面来完成此操作。例如：

shape.setAsBox((float) (bounds.getWidth()/2/MyGdxGame.PPM),
               (float) (bounds.getHeight()/2/MyGdxGame.PPM));

从double到float的可能有损转换
