OpenGL纹理未找到匹配的重载函数

Question

首先是我的Fragmenshader代码。

#version 330 core
struct Material{
       sampler2D diffuse;
};

struct Light{
vec3 position;

vec3 ambient;
vec3 diffuse;

};

in  vec3 Normal;
in  vec3 FragPos;
in vec3 TexCoords;

out vec4 color;

uniform vec3 viewPos;
uniform Material material;
uniform Light light;

void main()
{
 //ambient
 vec3 ambient = light.ambient * vec3(texture(material.diffuse, TexCoords));
 //Diffuse
 vec3 norm = normalize(Normal);
 vec3 lightDir = normalize(light.position - FragPos);
 float diff = max(dot(norm,lightDir),0.0);
 vec3 diffuse = light.diffuse * diff *vec3(texture(material.diffuse,TexCoords));
 color = vec4(ambient+diffuse,1.0f);

 }

如果我想编译，我会得到这样的错误：'texture'：not mathcing overloaded found (使用隐式转换)我查看了GLSL文档，但我看起来是正确的。之后，我在我的OpenGL文件中搜索了一个错误...但我看起来还好。

您正在尝试使用3D坐标从2D采样器读取数据。将in vec3 TexCoords更改为in vec2 TexCoords或将纹理查找从texture(material.diffuse, TexCoords)更改为texture(material.diffuse, TexCoords.xy)
