Shader woes

[Alienhead]

Hoping someone might spot instantly what I cant find wrong with my shader.. it won't run under LE.   Thanks for your time.

 

SHADER version 1
@OpenGL2.Vertex
#version 400
#define MAX_INSTANCES 256

@OpenGL4.Fragment
#version 400
#define BFN_ENABLED 1

out vec4 fragData0;
uniform float currenttime;
float time = currenttime/1000;
uniform vec2 buffersize;

uniform sampler2D texture1;
uniform bool isbackbuffer;

float range = 0.05;
float noiseQuality = 250.0;
float noiseIntensity = 0.0088;
float offsetIntensity = 0.02;
float colorOffsetIntensity = 1.3;

float rand(vec2 coord)
{
    return fract(sin(dot(coord.xy ,vec2(12.9898,78.233))) * 43758.5453);
}

float verticalBar(float pos, float uvY, float offset)
{
    float edge0 = (pos - range);
    float edge1 = (pos + range);

    float x = smoothstep(edge0, pos, uvY) * offset;
    x -= smoothstep(pos, edge1, uvY) * offset;
    return x;
}

void main(void)
{
	vec2 uv = gl_FragCoord.xy / buffersize.xy;
	if (isbackbuffer) uv.y = 1.0 - uv.y;

    for (float i = 0.0; i < 0.71; i += 0.1313)
    {
        float d = mod(time * i, 1.7);
        float o = sin(1.0 - tan(time * 0.24 * i));
    	o *= offsetIntensity;
        uv.x += verticalBar(d, uv.y, o);
    }
    
    float uvY = uv.y;
    uvY *= noiseQuality;
    uvY = float(int(uvY)) * (1.0 / noiseQuality);
    float noise = rand(vec2(time * 0.00001, uvY));
    uv.x += noise * noiseIntensity;

    vec2 offsetR = vec2(0.006 * sin(time), 0.0) * colorOffsetIntensity;
    vec2 offsetG = vec2(0.0073 * (cos(time * 0.97)), 0.0) * colorOffsetIntensity;
    
    float r = texture(texture1, uv + offsetR).r;
    float g = texture(texture1, uv + offsetG).g;
    float b = texture(texture1, uv).b;

    fragData0 = vec4(r, g, b, 1.0);
}

What does "not running" mean exactly? Does it link with the vertex shader?

[Alienhead]

It gives no error when I place it in Posteffetcs in the editor,  but attempting to move the mouse or move around in the editor creates a jaggedy pause like.

This is the post effect I was going for - https://www.shadertoy.com/view/ldjGzV

This works fine for me. Is the shader compiling? Or do you mean you get some kind of lag?



 

[Alienhead]

I set it  as Posteffect, but nothing happens,  then I am unable to move the camera around in the editor,  nothing happens. I remove the effect and operations resume as normal. 

No error on the bottom where you normally see errors when applying a bad shader.

[Alienhead]

I was able to build me a less dramatic effect using less shader commands.

[havenphillip]

Oh that one looks cooler anyway.

You have a big talent for "polishing" the appearance of a game and giving it a visual theme.

[Alienhead]

Much appreciated.

I've decided to place defendTHIS! project on hold until Ultra gets it's editor and stuff.. I'm going to move defendTHIS! over to Ultra.  In the mean time I'm finishing up my Galaga clone in LE, got about 2 months left on it - or less..
