What shader effects do you want?

Anyone able to convert this shader to C2?

This shader use standard derivatives not working for me in normal fx;

However i used shadertoy plugin ...

#extension GL_OES_standard_derivatives : enable

void mainImage( out vec4 fragColor, in vec2 fragCoord )

{

vec2 uv = fragCoord.xy / iResolution.xy;

vec2 size = vec2(iResolution.xy);

vec2 pixel = vec2(1.0) / size;

uv -= pixel * vec2(0.5);

vec2 uv_pixels = uv * size;

vec2 delta_pixel = fract(uv_pixels) - vec2(0.5);

vec2 ddxy = fwidth(uv_pixels )*3.5+sin(iTime)*9.0;

vec2 mip = log2(ddxy) - 0.5;

vec4 c1= texture2D(iChannel0, uv + (clamp(delta_pixel / ddxy, 0.0, 1.0) - delta_pixel) * pixel, min(mip.x, mip.y));

vec4 c2 = texture2D(iChannel0, uv); // debug

fragColor = vec4(c1);

}

you can copy past and try with this tool ...

thanks you McKack , i made my first shader with godot in 5 mins after quick reading doc ... never used godot!

just for fun tested godot and play with it; converting 2 shaders and exported to html5;

Heavy to load webasm ..

They speaking version 4.0 .. wait and see there ;

Neat! Yeah Godot is interesting but I'm pretty bad with code still.

Is the shadertoy plugin an addon for Construct 2? I'm a little unsure how I'd use that code in a project, if possible.

Thanks!

I can do that for you but standard derivatives not working for me with C2 runtime ! You must test de fx .. it will be ready for tomorrow .

Standard derivatives : dFdx, dFdy, and fwidth <-- this one is used in the shader you want

fwidth — return the sum of the absolute value of derivatives in x and y

I was always looking for some effect like this in construct!

Hi , this shader use buffer and multi texture iChannel0 - 1 - 2 ;

in past i converted something similar but ... you can find in effect list ;

if you really want this one , i can convert it wiht 1 texture and color blend.

First of all c2 use 2 texture one for front and the second for back this is the reason why we can not use shadertoy 4 textures based shader;

I think it's sound like this one ;
