Shader breaks camera

Question

I made a shader for my VBO cube (Coloring) and have some problems.

When enabling the shader, I can't move the camera.

My camera breaks with the shader enabled.

Cube.vert:

#version 330 core

layout(location = 0) in vec3 vertexPosition_modelspace;

// Notice that the "1" here equals the "1" in glVertexAttribPointer
layout(location = 1) in vec3 vertexColor;

// Output data ; will be interpolated for each fragment.
out vec3 fragmentColor;

void main()
{
    gl_Position.xyz = vertexPosition_modelspace;
    gl_Position.w = 1.0;

    // The color of each vertex will be interpolated
    // to produce the color of each fragment
    fragmentColor = vertexColor;
}

Cube.frag:

#version 330 core

// Interpolated values from the vertex shaders
in vec3 fragmentColor;

// Ouput data
out vec3 color;

void main(){
    // Output color = color specified in the vertex shader,
    // interpolated between all 3 surrounding vertices
    color = fragmentColor;
}

Answer 1

Try: Projection * View * Model

They are all 3 Mat4 Model would be: 1

Then push the stuff back to the shader.
