我是 Processing 的新手,我正在尝试创建一个交互式信息图,其中背景颜色会根据有关事件的最新推文是否包含正面或负面词语而变化。对于正面推文,背景将为黄色,而对于负面推文,背景将为红色。
我已经让该项目正常工作,以便它在控制台中显示提到“温布利”(事件)的最新推文。
我不知道如何在控制台数据中打印的文本中找到正面和负面的词。
为了尝试这样做,我设置了一个字符串数组来列出我想要触发背景颜色变化的所有正面和负面词:
String [] positiveWords = new String[6];
{
positiveWords [0] = "great";
positiveWords [1] = "love";
positiveWords [2] = "amazing";
positiveWords [3] = "fun";
positiveWords [4] = "brilliant";
positiveWords [5] = "good";
}
String [] negativeWords = new String[4];
{
negativeWords [0] = "bad";
negativeWords [1] = "hate";
negativeWords [2] = "terrible";
negativeWords [3] = "boring";
}
然后我在 void draw() 中添加了一个 if 语句
if (console.log = positiveWords) {
background (0, 100, 100);
}
if (console.log = negativeWords) {
background (255, 0, 0);
}
这将返回错误 'expecting LPAREN, found 'console'
几天来,我一直试图通过到处搜索来找到答案,但我不知所措!任何帮助将不胜感激!非常感谢。
