我试图修改从textured.vert样本中提取的着色器‘GamePlay3d’,但是得到了以下错误:
错误: 0:108:'‘:语法错误,不正确的预处理器指令 错误: 0:108:“‘:语法错误-在预处理器指令之后出现意外标记-需要换行符 错误: 0:112:'‘:语法错误,不正确的预处理器指令 错误: 0:112:“‘:语法错误--在预处理器指令之后出现意外标记--需要一个换行符 错误: 0:120:'‘:语法错误,不正确的预处理器指令 错误: 0:120:‘:语法错误--在预处理器指令之后出现意外标记--需要换行符
编辑:如果还原前12行,它可以工作!:

问题是,您在SPOT_LIGHT_COUNT中使用了常量POINT_LIGHT_COUNT和lighting.vert
例如,lighting.vert:46
#if (POINT_LIGHT_COUNT > 0)当POINT_LIGHT_COUNT无法替换时,将不会编译。
您可以像在原始文件中那样定义这两个常量,或者在lighting.vert中清除对它们的引用。
