After writing a piece of text, we create a cclabelttf, which is called the body cclabelttf. Then, four cclabelttf are created. The color is black and the size is the same as that of the body. It is called the stroke cclabelttf. You may have understood this. That's right. Put the four strokes, cclabelttf, under the body of the cclabelttf, on the left and right, and the body of the cclabelttf, respectively, in this way, the stroke effect is achieved .. * String text * fontname text font type * fontsize text size * color3 text color * linewidth stroke width */cclabelttf * helloworld: textaddstroke (const char * string, const char * fontname, float fontsize, const cccolor3b & color3, float linewidth) {// body cclabelttf * center = cclabelttf: Create (string, fontname, fontsize ); center-> setcolor (color3); // stroke cclabelttf * up = cclabelttf: Create (string, fontname, fontsi Ze); Up-> setcolor (ccblack); Up-> setposition (CCP (center-> getcontentsize (). width * 0.5, center-> getcontentsize (). height * 0.5 + linewidth); Center-> addchild (up,-1); // cclabelttf under cclabelttf * down = cclabelttf: Create (string, fontname, fontsize); down-> setcolor (ccblack); down-> setposition (CCP (center-> getcontentsize (). width * 0.5, center-> getcontentsize (). height * 0.5-linewidth); Center-> addchild (down,-1 ); // Stroke cclabelttf left cclabelttf * Left = cclabelttf: Create (string, fontname, fontsize); left-> setposition (CCP (center-> getcontentsize (). width * 0.5-linewidth, center-> getcontentsize (). height * 0.5); left-> setcolor (ccblack); Center-> addchild (left,-1); // stroke cclabelttf right cclabelttf * Right = cclabelttf :: create (string, fontname, fontsize); Right-> setcolor (ccblack); Right-> setposition (CCP (center-> getcontentsize ().
