Question

我在屏幕上显示文本时遇到一些问题，过去我刚刚使用基于精灵的文本，但这次我想使用UnicodeFont。 TrueTypeFonts完全绘制，但不推荐使用。

当我尝试绘制UnicodeFont时，它似乎受到我使用的字符的影响。例如，如果我绘制字符串“stackoverflow”文本和框将绘制，如果我尝试“stackoverflowcom”框不会绘制。

我的源代码的准系统版本如下。在线~74我调用uniFont.drawString（0,0，“stackoverflow”）; ，如果com（或任何真的）将不会绘制框。

修改。＆GT;您可以使用boolean tryUnicode在true和unicode之间进行交换。

我曾尝试将它们粘贴到单独的显示列表中，但它没有任何区别。

任何人都可以提供有关为何发生这种情况的见解吗？

谢谢

Answer 1

现在看来我有这个错误，它只会在使用字体之前绘制轮廓矩形。这似乎是 Slick错误，并且是一个主要问题，所以他们应该在添加新功能之前修复它。唯一的解决方法是在您的框架上渲染最后字体。

编辑：问题解决了！

渲染字体后添加此行：

GL11.glDisable(GL11.GL_TEXTURE_2D);

光滑的人应该真正添加该行，因为它会导致如此多的错误！

Answer 2

这是我创建字体的方式：

Font font = ...; //Your loaded font
float size = 20.0F;
UnicodeFont f = new UnicodeFont(font.deriveFont(0 /*normal*/, size));
f.addAsciiGlyphs();
ColorEffect e = new ColorEffect();
e.setColor(java.awt.Color.white);
f.getEffects().add(e);
try {
    f.loadGlyphs();
} catch (SlickException e1) {
    e1.printStackTrace();
}
return f;

希望这有帮助！
