Libgdx渲染地板3D游戏 [英] Libgdx rendering floor for 3D game

问题描述

在我的第一个3D游戏的我现在要渲染的地板上，这实际上是对 Y = 0的平面（不是libgdx 平面） 。

In my first 3D game i now want to render the floor, which is actually a plane (not a libgdx Plane) on y = 0.

我想添加一个纹理来了，这样我就可以在每个级别的不同楼层。

I want to add a Texture to it, so i can have different floors in each level.

现在我的问题是：什么是创建和渲染这种纹理的地板最好的方法是什么？

Now my question is: What is the best way to create and render this textured floor?

我想过使用基本块模型制作与模型构建器，然后添加一个纹理，但我只能看到1的6个面二维纹理就足够了，所以我想到了一个飞机。

I thought about using basic Block Models made with ModelBuilder and then added a Texture, but as i can only see 1 of 6 faces a 2d Texture would be enough, so i thought about a Plane.

我可以添加一个纹理到平面，因为它是在3D房间无限的脸？最后一件事的话，我想到是在贴花秒。

Can i add a Texture to a Plane, as it is a infinite face in 3D room? The last thing i then thought about were the Decals.

为贴花 S I期待的？以及如何使用它们？或者你有其他的解决办法。

Are Decals what i am looking for? And how can i use them? Or do you have an other solution .

任何教程或其他帮助将是巨大的。

Any tutorial or other help would be great.

感谢

推荐答案

一是关于贴花，贴花像精灵，但在三维坐标，使用这样的：

First about Decals, decals are like Sprites but in 3d coordinate, use it like this:

私人贴纸贴花; 私人DecalBatch decalBatch;

private Decal decal; private DecalBatch decalBatch;

在显示（）或创建（）

decalBatch = new DecalBatch();
CameraGroupStrategy cameraGroupStrategy = new CameraGroupStrategy(camera);
decal = Decal.newDecal(textureRegion, true);
decal.setPosition(5, 8, 1);
decal.setScale(0.02f);
decalBatch.setGroupStrategy(cameraGroupStrategy);

在渲染（）

//Add all your decals then flush()
decalBatch.add(decal);
decalBatch.flush();

还配置有decalBatch.dispose（）;

also dispose with decalBatch.dispose();

请注意，在未来的贴纸将3D的一部分，我个人不建议您使用三维平面使用贴花作为我自己，我发现了一些问题有了它，使用这样的三维平面的使用，我贴我的一些$的C $ CS此处

notice that in future decal will be part of 3d, I personally do not encourage you to use Decals as myself using 3d plane and I saw some problems with it, to use 3d plane use like these, i paste some of my codes here

private Model createPlaneModel(final float width, final float height, final Material material, 
            final float u1, final float v1, final float u2, final float v2) {

modelBuilder.begin();
MeshPartBuilder bPartBuilder = modelBuilder.part("rect", 
GL10.GL_TRIANGLES, Usage.Position | Usage.Normal | Usage.TextureCoordinates, 
material);
//NOTE ON TEXTURE REGION, MAY FILL OTHER REGIONS, USE GET region.getU() and so on
bPartBuilder.setUVRange(u1, v1, u2, v2);
        bPartBuilder.rect(
                -(width*0.5f), -(height*0.5f), 0, 
                (width*0.5f), -(height*0.5f), 0, 
                (width*0.5f), (height*0.5f), 0, 
                -(width*0.5f), (height*0.5f), 0,
                0, 0, -1);


        return (modelBuilder.end());
    }

纹理可以添加属性材料

texture can be added as attribute to material

material.set(new TextureAttribute(TextureAttribute.Diffuse, texture)

透明飞机已经阿尔法添加到其他属性的

for transparent plane that has alpha add to other attribute

attributes.add( new BlendingAttribute(color.getFloat(3)));          
attributes.add( new FloatAttribute(FloatAttribute.AlphaTest, 0.5f));

material.set(attributes);

初​​始化的ModelInstance来获取返回的模型

Init the ModelInstance to get model that returned

modelInstance = new ModelInstance(createPlaneModel(...))

渲染渲染（）与ModelBatch对象

render in render() with ModelBatch object

modelBatch.render(modelInstance );
