scene2d键缩放与libgdx [英] scene2d button scaling with libgdx

问题描述

我不知道这是否只是我，但<一个href="http://libgdx.badlogicgames.com/nightlies/docs/api/com/badlogic/gdx/scenes/scene2d/utils/Drawable.html"相对=nofollow>可绘制我迷惑。难道他们打算继续给他们的大小，或者是有没有办法在其中缩放图像？据我所知，他们可以用ninepatch通过拉伸图像，以填补某些领域，但我想它延伸到缩放图像。我使用的是<一href="http://libgdx.badlogicgames.com/nightlies/docs/api/com/badlogic/gdx/scenes/scene2d/ui/TextButton.html"相对=nofollow> TEXT按钮 我的菜单按钮，但他们是太大了，我很想知道如何去衡量他们。我从检索一本地图册，其中有ninepatch图像，它的皮肤。 下面是设置界面： 下面是我使用的是包中的图片： 这里是TextureAtlas的初始化，和皮肤：

I don't know if it is just me, but drawables confuse me. Are they intended to keep the size they are given, or is there a way to scale the image within them? I understand they can use ninepatch to fill certain areas by stretching an image, but I want to scale the image that it stretches. I am using a TextButton for my menu buttons, but they are way too big, and I would love to know how to scale them. I am retrieving the skin from an atlas, which has ninepatch images in it. Here is the settings screen: Here are the images in the pack I am using: Here is the initialization of the TextureAtlas, and Skin:

buttonAtlas = new TextureAtlas(Gdx.files.internal("buttons/buttons.pack"));
buttonSkin = new Skin(buttonAtlas); 

下面是菜单按钮的初始化。

Here is the initialization of that menu button.

TextButtonStyle textButtonStyle = new TextButtonStyle();
textButtonStyle.up = Assets.buttonSkin.getDrawable("bluebutton");
textButtonStyle.down = Assets.buttonSkin.getDrawable("redbutton");
textButtonStyle.font = font;

buttonMenu = new TextButton("Menu", textButtonStyle);
buttonMenu.pad(20.0f);
buttonMenu.addListener(new ClickListener() {
    @Override
    public void clicked(InputEvent event, float x, float y) {
        game.fade.startFadeOut();
        super.clicked(event, x, y);
    }
});

也许我可以改变我如何把它放在桌子上，或如何我在舞台上把表？

And perhaps I could change how I put it in the table, or how I put the table in the stage?

table.add(buttonMenu).width(Gdx.graphics.getWidth()/4);
stage.addActor(table);

作为最后的手段，我想我可以尝试创建我自己的文字按钮的演员，我可以扩展，感谢您的时间。

As a last resort I suppose I could attempt creating my own text button actor that I could scale, thank you for your time.

推荐答案

首先，如果你知道你的图片过大：最好的办法是缩放图像本身，以更小的尺寸，然后用TexturePacker也产生新TextureAtlas包含更小的图像。

First of all if you know that your images are too big: The best would be to scale the images themselves to a smaller size and then use the TexturePacker too generate a new TextureAtlas that contain the smaller images.

总之，你可以将图像缩放按钮，用TableLayout，如果你真的想，看到的例子：

Anyhow you can scale the image button with the TableLayout if you really want to, see example:

table.add(buttonMenu).width(100).height(100);
