我用andengine编写游戏,我正在使用Andengine Text显示高分......
这是代码:
StrokeFont mFont = FontFactory.createStrokeFromAsset(this.getFontManager(), mainFontTexture, this.getAssets(), "Roboto-BoldItalic.ttf", 100, true, Color.WHITE, 2, Color.BLACK);
mFont.load();
text_score_menu = new Text(25, 25, mFont, "Score: ",getVertexBufferObjectManager());
if(LC.Score>Constants.highScore){
prefs.edit().putInt("highScore",LC.Score).commit();
text_score_menu.setText("New High: " + LC.Score);
}else{
text_score_menu.setText("Score: " + LC.Score);
}
问题是,当有新的高分时,我在这里得到一个新的例外:
text_score_menu.setText("New High: " + LC.Score);
但是当分数不是新的高分并且分数显示为
时,我没有这个问题text_score_menu.setText("Score: " + LC.Score);
这是错误消息:

答案 0 :(得分:8)
这是AndEngine中常见的文本陷阱 - 当您实例化text_score_menu实体时,则设置最大长度。尝试更改此
text_score_menu = new Text(25, 25, mFont, "Score: ",getVertexBufferObjectManager());
到
text_score_menu = new Text(25, 25, mFont, "New High: 123456789",getVertexBufferObjectManager());
将建立足够长的文本字段 - 然后确保在显示实体之前“设置”正确的文本 - (正如您在所呈现的代码中所做的那样)
