libgdx polygon sprite batch draw filled polygon - colors

Question

I need to draw polygon filled with color, but i don't know how to create my texture right, for batch to draw it
Here is my code
public class VisualComponent implements Component, Pool.Poolable {
public float[] vertices = new float[1];
public short[] triangles = new short[1];
#Override
public void reset() {
vertices = new float[1];
triangles = new short[1];
}
}
Here i am creating the entity which i want to be drawn
Entity source = engine.createEntity();
TransformComponent transformComponent = engine.createComponent(TransformComponent.class);
VisualComponent visualComponent = engine.createComponent(VisualComponent.class);
float redColorBits = Color.RED.toFloatBits();
visualComponent.vertices = new float[]{
0, 0, redColorBits,
10, 0, redColorBits,
10, 10, redColorBits,
0, 10, redColorBits
};
visualComponent.triangles = new short[]{
0, 1, 2,
0, 2, 3
};
source.add(transformComponent);
source.add(visualComponent);
engine.addEntity(source);
And here is the rendering system's processEntity method
#Override
protected void processEntity(Entity entity, float deltaTime) {
TransformComponent transformComponent = tcm.get(entity);
VisualComponent visualComponent = vcm.get(entity);
batch.draw(new Texture(1, 1, Pixmap.Format.RGBA8888),
visualComponent.vertices, 0, visualComponent.vertices.length,
visualComponent.triangles, 0, visualComponent.triangles.length);
}
Also I need a tip on how to correctly reuse my texture for not always recreating it. Thx

Answer 1

Okay I did it by inheriting from PolygonSpriteBatch and adding a 1x1 white pixel texture for draw function, here is the code which worked fine.
public class TexturedPolygonSpriteBatch extends PolygonSpriteBatch {
private Texture texture;
public TexturedPolygonSpriteBatch() {
super();
initTexture();
}
public void draw(float[] polygonVertices, int verticesOffset, int verticesCount,
short[] polygonTriangles,
int trianglesOffset, int trianglesCount) {
super.draw(texture, polygonVertices, verticesOffset, verticesCount,
polygonTriangles, trianglesOffset, trianglesCount);
}
#Override
public void dispose() {
texture.dispose();
super.dispose();
}
private void initTexture() {
Logger.log(getClass(), "Initializing 1x1 white texture");
Pixmap pixmap = new Pixmap(1, 1, Pixmap.Format.RGBA8888);
pixmap.setColor(Color.WHITE);
pixmap.fill();
texture = new Texture(pixmap);
pixmap.dispose();
}
}
Actually it was important to give a white color to the texture, because white color contains all the colors, if I set red color, only red color could be drawn there, think its some kind-a strange, but the woodoo worked.)
