如何绘制多边形填充？ [机器人，Andengine] [英] How to draw filled polygon ? [Android, Andengine]

问题描述

我想提请填充多边形Andengine gles2。

I want to draw filled polygon in Andengine gles2.

我有多边形顶点。我怎么能画呢？的问题是，它可以具有任何数量的顶点（4，30）。

I have vertices of polygon. How I can draw it? The problem is that it can have any number of vertices (4, 30).

接下来的问题是，我想填补这个多边形我的形象（或只是颜色如果没有可能）。

Next problem is that I want fill this polygon with my image(or just color if not possible).

T能够找到这个任何功能。可能吗 ？

Can' t find any function for this. Is it possible ?

推荐答案

这样，您就可以在它的重复图像创建多边形。

This way you can create polygon with repeating image in it.

final float offsetX = 0f;
final float offsetY = 115f;
final float[] vertexX1 = { 200f-offsetX, 400f-offsetX, 300f-offsetX, 200f-offsetX};
final float[] vertexY1 = { 200f-offsetY, 200f-offsetY, 300f-offsetY, 300f-offsetY};

final TexturedPolygon myRepeatingSpriteShape = new TexturedPolygon(offsetX, offsetY,       vertexX1, vertexY1, myTextureRegion, this.getVertexBufferObjectManager());
mScene.attachChild(myRepeatingSpriteShape);

这实现由社区成员的 recastrodiaz 的一个创造。我认为这将解决您的问题。
