在 libgdx 中加载纹理图的区域会加载整个文件

问题描述

我设法用我拥有的图像打包一个纹理图集，它可以正常工作，因为它会创建 .pack 文件和 .png 文件.问题是当我加载纹理图集并尝试分配 AtlasRegions 时.它加载整个图集，而不仅仅是我想要的图像.这是我用来测试它的模型代码.

I managed to pack a textureatlas with images i have and it works properly in that it creates the .pack file and the .png file. The issue is when i load the texture atlas and try to assign AtlasRegions. it loads the entire atlas instead of only the image i want. here is a mockup code i used to test it.

@Override
public void create() {
    camera = new OrthographicCamera(800, 480);
    batch = new SpriteBatch();

    test = new TextureAtlas(Gdx.files.internal("polytest.png"));

    sprite = test.findRegion("hero");
    texture = new Texture(Gdx.files.internal("data/libgdx.png"));
    texture.setFilter(TextureFilter.Linear, TextureFilter.Linear);


}

@Override
public void render() {
    Gdx.gl.glClearColor(1, 1, 1, 1);
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

    batch.setProjectionMatrix(camera.combined);
    batch.begin();
    batch.draw(sprite.getTexture(), 10, 10);
    batch.end();
}

这会渲染整个地图集，而不仅仅是地图集中名为英雄"的图像.为什么会这样?

this renders the entire atlas instead of only the image called "hero" in the atlas. Why does this happen?

提前致谢.

推荐答案

当你这样做时.-

batch.draw(sprite.getTexture(), 10, 10);

您实际上是在告诉 libgdx 渲染整个 Texture.您只需要绘制 TextureRegion.-

you're actually telling libgdx to render the whole Texture. What you need is to draw just the TextureRegion.-

batch.draw(sprite, 10, 10);
