I'm trying to use if statement in my fragment shader.
I want to compare my in int finalLightType[4];
Here is my vertex shader code and fragment shader code:
Vertex:
#version 400 core
in vec3 position;
in vec2 textureVector;
in vec3 normalVector;
out vec3 color;
out vec3 surfaceNormal;
out vec2 textureCoords;
out float visibility;
out vec3 toLightVector[4];
out int finalLightType[4];
uniform vec3 mainColor;
uniform mat4 transformationMatrix;
uniform mat4 projectionMatrix;
uniform mat4 viewMatrix;
uniform float tilingX;
uniform float tilingY;
uniform float density = 0.01;
uniform float gradient = 1.5;
uniform int lightType[4];
uniform float lightRange[4];
uniform vec3 lightPosition[4];
void main(void)
{
finalLightType[0] = 1;
color = mainColor;
textureCoords = textureVector;
textureCoords.x = textureCoords.x * tilingX;
textureCoords.y = textureCoords.y * tilingY;
vec4 worldPosition = transformationMatrix * vec4(position,1.0);
vec4 positionRelativeToCam = viewMatrix * worldPosition;
float distance1 = length(positionRelativeToCam.xyz);
visibility = exp(-pow((distance1 * density), gradient));
visibility = clamp(visibility,0.0,1.0);
surfaceNormal = (transformationMatrix * vec4(normalVector,0.0)).xyz;
gl_Position = projectionMatrix * positionRelativeToCam;
}
You can see out int finalLightType[4]; and finalLightType[0] = 1;
Fragment:
#version 400 core
in vec3 color;
in vec3 surfaceNormal;
in vec2 textureCoords;
in float visibility;
in vec3 toLightVector[4];
in int finalLightType[4];
out vec4 out_Color;
uniform bool textured;
uniform sampler2D sampler;
uniform vec3 bgColor;
uniform vec3 ambientColor;
uniform vec3 lightColor[4];
uniform float lightIntensity[4];
uniform vec3 lightDir[4];
uniform float lightSpotAngle[4];
void main(void)
{
vec3 unitSurfaceNormal = normalize(surfaceNormal);
if(finalLightType[0] == 0)
{
}
if(textured == true)
{
out_Color = texture2D(sampler,textureCoords);
}
else
{
out_Color = vec4(color,1.0);
}
out_Color = mix(vec4(bgColor,1.0),out_Color,visibility);
vec3 convAmbientColor = vec3(1.0,1.0,1.0) - ambientColor;
out_Color = out_Color - vec4(convAmbientColor,1.0);
out_Color.w = 1.0;
}
Everything looks good, but if I start my game I receive really strange effect (Uncolored, untextured, transformed on the front of the camera object):
But.. If I try to compare another int same way, but not in variable, but local variable (Or even uniform variable, they works fine too):
#version 400 core
in vec3 color;
in vec3 surfaceNormal;
in vec2 textureCoords;
in float visibility;
in vec3 toLightVector[4];
in int finalLightType[4];
out vec4 out_Color;
uniform bool textured;
uniform sampler2D sampler;
uniform vec3 bgColor;
uniform vec3 ambientColor;
uniform vec3 lightColor[4];
uniform float lightIntensity[4];
uniform vec3 lightDir[4];
uniform float lightSpotAngle[4];
void main(void)
{
vec3 unitSurfaceNormal = normalize(surfaceNormal);
int lightTyp = 0;
if(lightTyp == 0)
{
}
if(textured == true)
{
out_Color = texture2D(sampler,textureCoords);
}
else
{
out_Color = vec4(color,1.0);
}
out_Color = mix(vec4(bgColor,1.0),out_Color,visibility);
vec3 convAmbientColor = vec3(1.0,1.0,1.0) - ambientColor;
out_Color = out_Color - vec4(convAmbientColor,1.0);
out_Color.w = 1.0;
}
It only happens if I compare in variables, everything is works fine with uniform variables, local variables, etc.. (Also tried with varying variable).
Edit:
This object after I run my game is always on the front of the camera and never rotates or whatever. I can't also see other object like a cube that should appear something (probably my camera is inside this cube and I can't see it because of culling faces).
