Hi there%

I am sure you need something like this on your games ...

And Live Demo.

http://gigatron3k.free.fr/html5/C2/FX/Rays

Update : Human brain forever ... i worked on with lightspeed.. and this FX is 99% done !

Finaly the fx File:

http://gigatron3k.free.fr/html5/C2/FX/rotaterays.rar

Tips : Vec2 = 2 values parameters like X.Y to access X do; vec2(0.2,0.0) << now x=0.2 and y=0

vec3 is 3 values params ; X,Y,Z..

vec4 is 4 values paramz; X,Y,Z,W <--- W ????? yes no letters after Z !

Enjoy the meditation./

Ok .. I know this error happened when gfx card memory is overflowed du to big shaders.

If you want i can reduce numbers of FX by 2.

One shaders fx with 0-12 FX and the other 13-25 FX..

waiting your response .

This one is not easy but:

Find Noise texture and change this line ;

float noise( in vec3 x ) // iq noise function
{
	vec3 p = floor(x);
    vec3 f = fract(x);
	f = f*f*(3.0-2.0*f);
//	vec2 uv = (p.xy+vec2(37.0,17.0)*p.z) + f.xy;       <------ This line
	vec2 uv = (vTex.xy+vec2(37.0,17.0)*p.z) + f.xy;  <------ By this one 
	vec2 rg = texture2D( samplerFront, (uv+ 0.5)/256.0, -100.0 ).yx;
 
	return mix( rg.x, rg.y, f.z ) * 2.0 - 1.0;
}[/code:36ifde3r]
good luck ... hope this will help you, or find Fire shaders on glslsandbox ..

Regards

It is possible to make something like that in Construct 2?

https://www.shadertoy.com/view/lsSGWw

In strange case like this ,some shaders are not running on c2 like Shadertoy.

however ; I do not change much in the original source.
