Shader problem

[JHAM25]

Describe your problem here.

When I put this shader in the game it doesn't seem to work. I've tried others and they work. Does anyone know why it doesn't work?
#pragma header
uniform float iTime;
uniform vec2 WaveCentre;
uniform float enabled;
uniform vec2 iResolution;

void main()
{

float offset = (iTime- floor(iTime))/iTime;
float CurrentTime = (iTime)*(offset);    

vec3 WaveParams = vec3(12.0, 1.0, 0.1 ); 

float ratio = iResolution.y/iResolution.x;

   
//vec2 WaveCentre = vec2(0.5, 0.5);

// WaveCentre.y *= ratio;

vec2 texCoord =  openfl_TextureCoordv;      
float Dist = distance(vec2(texCoord.x, texCoord.y*ratio), vec2(WaveCentre.x, WaveCentre.y*ratio));

vec4 Color = flixel_texture2D(bitmap,texCoord);

if ((Dist <= ((CurrentTime) + (WaveParams.z))) &&
(Dist >= ((CurrentTime) - (WaveParams.z))))
{

	float Diff = (Dist - CurrentTime); 
	float ScaleDiff = (1.0 - pow(abs(Diff * WaveParams.x), WaveParams.y)); 
	float DiffTime = (Diff  * ScaleDiff);
    

	vec2 DiffTexCoord = normalize(texCoord - WaveCentre);         
    

	texCoord += ((DiffTexCoord * DiffTime) / (CurrentTime * Dist * 40.0));
	Color = flixel_texture2D(bitmap,texCoord);
    
  
	Color += (Color * ScaleDiff) / (CurrentTime * Dist * 40.0);
} 

if (enabled == 1.0)
{   
    gl_FragColor = Color; 
}
else
{
    gl_FragColor = flixel_texture2D(bitmap,openfl_TextureCoordv);
}

}
