为什么老说我那两个shader文件打不开呢？请多帮忙，谢谢！

"shaders/temp.frag"

3# aya_daxiang
("shaders/temp.frag");
对呀我是这样用的呀

array 版主，难道是必须用绝对路径吗？

FlySky 发表于 2010-10-7 02:25:43

没有规定一定要使用绝对路径～～相对路径也没问题的～～～～～关键是您是否设置正确的路径～～

gis_wudi 发表于 2011-5-30 11:43:13

“shaders\\temp.frag”
两个斜线哦

gis_wudi 发表于 2011-5-30 11:44:05

c或c++路径是要双斜线的

阿威 发表于 2012-6-11 12:55:16

你能不能先用绝对路径试试来出来问
