NGUI 解決UILable 在空行起始位置加‘\n’

NGUI 解決UILable 默認在頂滿第一行時，在起始位置如鍵入空格無效，其緣由就是會加入換行符，使字符串，總體換行了

 

解決辦法加入bool變量控制

1在 UILable代碼中添加

[HideInInspector][SerializeField] public bool wrapText = true;

 2 在該函數中 void ProcessText (bool legacyMode, bool full)

對方法

 // Wrap the text     

bool fits = NGUIText.WrapText(mText, out mProcessedText, true, wrapText);添加參數

 

3 在NGUIText源碼中相應函數添加參數

static public bool WrapText (string text, out string finalText)
    {
        return WrapText(text, out finalText, false);
    }

static public bool WrapText (string text, out string finalText, bool keepCharCount, bool needWrap = true)

 

// Doesn't fit?
            if (Mathf.RoundToInt(remainingWidth) < 0)
            {
                // Can't start a new line 在此處添加判斷 !needWrap 來阻止建立新行，就解決問題了  
                   if ( !needWrap || lineIsEmpty || lineCount == maxLineCount)
                {
                    // This is the first word on the line -- add it up to the character that fits
                    sb.Append(text.Substring(start, Mathf.Max(0, offset - start)));
                    bool space = IsSpace(ch);
                    if (!space && !eastern) fits = false;

                    if (lineCount++ == maxLineCount)
                    {
                        start = offset;
                        break;
                    }

                    if (keepCharCount) ReplaceSpaceWithNewline(ref sb);
                    else EndLine(ref sb);

                    // Start a brand-new line
                    lineIsEmpty = true;

                    if (space)
                    {
                        start = offset + 1;
                        remainingWidth = regionWidth;
                    }
                    else
                    {
                        start = offset;
                        remainingWidth = regionWidth - glyphWidth;
                    }
                    prev = 0;
                }
                else
                {
                    // Revert the position to the beginning of the word and reset the line
                    lineIsEmpty = true;
                    remainingWidth = regionWidth;
                    offset = start - 1;
                    prev = 0;

                    if (lineCount++ == maxLineCount) break;
                    if (keepCharCount) ReplaceSpaceWithNewline(ref sb);
                    else EndLine(ref sb);
                    continue;
                }
