使用PolygonSpriteBatch在Libgdx中渲染具有重复纹理的多边形 [英] Render polygon with repeate Texture in Libgdx using PolygonSpriteBatch

问题描述

我想绘制一个具有重复纹理的多边形(例如砖).这是我的代码:

I would like to draw a polygon with repeat texture (e.g brick). Here is my code:

textureBrick = new Texture(Gdx.files.internal("data/brick.png"));
textureBrick.setWrap(TextureWrap.Repeat, TextureWrap.Repeat);


TextureRegion texreg = new TextureRegion(textureBrick,0,0,1f,1f);
texreg.setTexture(textureBrick);
PolygonRegion po = new PolygonRegion(texreg, floatvertices);

然后我进行绘制(渲染):

and next i draw (render):

public void render(SpriteBatch spriteBatch, PolygonSpriteBatch polygonBatch) {
    Gdx.gl.glEnable(GL10.GL_TEXTURE_2D);
    polygonBatch.draw(po, 0,0, 512f, 256f);
}

不幸的是，我总是得到用白色填充的多边形.为什么?

Unfortunately, I always gets polygons filled by white colour. Why?

推荐答案

您可能会以此顺序调用代码

You might be calling code in this order

spriteBatch.begin();
spriteBatch.draw(textureRegion, 0, 0, 480, 480);
polygonBatch.begin();
polygonBatch.draw(polygonRegion, 0,0, 400f, 400f);  
polygonBatch.end();
spriteBatch.end();

同时使用spriteBatch，polygonBatch，shapeRenders等可能会导致此类问题，您应该单独使用它们:

Using spriteBatch,polygonBatch, shapeRenders etc together might lead to this type of problem you should use them seperately :

spriteBatch.begin();
spriteBatch.draw(textureRegion, 0, 0, 480, 480);
spriteBatch.end();
polygonBatch.begin();
polygonBatch.draw(polygonRegion, 0,0, 400f, 400f);  
polygonBatch.end();

在使用任何其他批次的开始之前，您应该结束上一个批次.

Before using begin of any other batch you should end the previous batch.
