绘制在libgdx中旋转的BitmapFont [英] Draw a BitmapFont rotated in libgdx

问题描述

我似乎无法弄清楚如何正确旋转位图字体.我认为您修改了SpriteBatch的转换矩阵.但是，尝试旋转会使文本绕某个点旋转，我不知道如何相对于文本本身旋转它.

I can't seem to figure out how to rotate a Bitmap font correctly. I think you modify the transformation matrix of the SpriteBatch. However, trying to rotate that rotates the text around some point, and I don't know how to rotate it relative to the text itself.

推荐答案

您可以尝试以下代码:

Matrix4 mx4Font = new Matrix4();
BitmapFont font;
SpriteBatch spriteFont;

font = new BitmapFont(Gdx.files.internal("data/font/agencyFB.fnt"), Gdx.files.internal("data/font/agencyFB.png"), true); //must be set true to be flipped
mx4Font.setToRotation(new Vector3(200, 200, 0), 180);
spriteFont.setTransformMatrix(mx4Font);
spriteFont.begin();
font.setColor(1.0f, 1.0f, 1.0f, 1.0f);
font.draw(spriteFont, "The quick brown fox jumped over the lazy dog", 100, 110);
spriteFont.end();
