在使用 libgdx 制作的游戏中,我有一个 TextureAtlas
,其中存储了我的 Animation
的所有 TextureRegion
代码>播放器代码>.Player
默认有一件蓝色 T 恤(例如).现在我希望能够拥有多个 Player
并且每个都应该有另一种 T 恤颜色.所以基本上,我想将第二个 Player
的蓝色替换为红色,第三个 Player
替换为绿色,依此类推.我确信我可以用 PixMap
做到这一点,但不会.因为那样我就失去了 TextureAtlas
(?) 的优势.还有另一种方法可以做到这一点吗?或者我需要在 TextureAtlas
中将每个颜色版本"作为 TextureRegion
吗?
In a game made with libgdx I have a TextureAtlas
in which I have stored all the TextureRegion
s for my Animation
s of the Player
. The Player
by default has a blue T-Shirt (for example). Now I would like to be able to have more then one Player
and each should have another T-Shirt color. So basically, I want to replace the blue with red for the second Player
and with green for the 3rd Player
and so on. I am sure I can do this with PixMap
but wouldn't. Because then I lose the advantage of the TextureAtlas
(?).
Is there another way to do this? Or do I need to have every "color version" as a TextureRegion
in the TextureAtlas
?
另一个小问题:
使用 Gimp(可能还有一些其他程序),您可以为.gif"文件使用颜色索引.通过为文件中的每种颜色保存一个索引,然后使用该索引来描述像素,这可以减小所有 Texture
的大小.因此,对于每个红色像素,您将有一个1"而不是#FF0000",并且在文件中的某处您有一个1=#FF0000".如果我们随后在 TextureAtlas
中将带有颜色索引的.gif"文件打包,那么索引会丢失并恢复默认的 RGB 颜色还是会产生问题?
Another little question:
With Gimp (and maybe a few other programs) you can use color indexes for ".gif" files. This reduces the size of all your Texture
s by saving an index for every color in the file and then using this index to describe the pixels. So for every red pixel you would have a "1" instead of "#FF0000" and somewhere in the file you have a "1=#FF0000". If we then pack the ".gif" files with the color indexes inside a TextureAtlas
, is the index then lost and it restores the default RGB colors or will that make problems?
非常感谢!
我在使用相同纹理生成随机颜色的武器时遇到了同样的问题.
I faced the same Issue for generating weapon with random colors using the same texture.
所以我写了这个.
基本上,我会为您要编辑的纹理制作像素图.
So I wrote this.
Basically I make a pixmap of the texture you want to edit.
然后你迭代所有的像素,在迭代的同时我检查某些颜色,这些颜色是纹理的特定部分.(我建议使用不同深浅的灰色,因为 RGB 是相同的)
然后,当它位于需要更改颜色的像素上时,我使用颜色选择器方法为这些像素组获取颜色,该方法基本上是随机的,从预制颜色数组中获取颜色,
然后将该特定像素更改为新颜色.
Then you iterate over all of the pixels, while iterating I check for certain colors which are a part specific part of the texture. (I suggest using different shades of gray since the RGB is the same)
Then when it is on a pixel where the color needs to be changed I grab a color for those pixel groups using a color picker method which is basically random which gets a color from a prefabbed color array,
and then changes that specific pixel to the new color.

*/
private static Texture genTexture(String texturename, int colorBlade,
int colorEdge, int colorAffinity, int colorGrip, int colorExtra) {
Texture tex = Game.res.getTexture(texturename);
TextureData textureData = tex.getTextureData();
textureData.prepare();
Color tintBlade = chooseColor(mainColors);
Color tintEdge = new Color(tintBlade.r + 0.1f, tintBlade.g + 0.1f,
tintBlade.b + 0.1f, 1);
Color tintAffinity = chooseColor(affinityColors);
Color tintGrip;
Color tintExtra = chooseColor(extraColors);
boolean colorsAreSet = false;
do {
tintGrip = chooseColor(mainColors);
if (tintAffinity != tintBlade && tintAffinity != tintGrip
&& tintGrip != tintBlade) {
colorsAreSet = true;
}
} while (!colorsAreSet);
Pixmap pixmap = tex.getTextureData().consumePixmap();
for (int y = 0; y < pixmap.getHeight(); y++) {
for (int x = 0; x < pixmap.getWidth(); x++) {
Color color = new Color();
Color.rgba8888ToColor(color, pixmap.getPixel(x, y));
int colorInt[] = getColorFromHex(color);
if (colorInt[0] == colorBlade && colorInt[1] == colorBlade
&& colorInt[2] == colorBlade) {
pixmap.setColor(tintBlade);
pixmap.fillRectangle(x, y, 1, 1);
} else if (colorInt[0] == colorEdge && colorInt[1] == colorEdge
&& colorInt[2] == colorEdge) {
pixmap.setColor(tintEdge);
pixmap.fillRectangle(x, y, 1, 1);
} else if (colorInt[0] == colorAffinity
&& colorInt[1] == colorAffinity
&& colorInt[2] == colorAffinity) {
pixmap.setColor(tintAffinity);
pixmap.fillRectangle(x, y, 1, 1);
} else if (colorInt[0] == colorGrip && colorInt[1] == colorGrip
&& colorInt[2] == colorGrip) {
pixmap.setColor(tintGrip);
pixmap.fillRectangle(x, y, 1, 1);
}
else if (colorInt[0] == colorExtra && colorInt[1] == colorExtra
&& colorInt[2] == colorExtra) {
pixmap.setColor(tintExtra);
pixmap.fillRectangle(x, y, 1, 1);
}
}
}
tex = new Texture(pixmap);
textureData.disposePixmap();
pixmap.dispose();
return tex;
}
我希望这会有所帮助.
