How to put a shader into unity that you found on a site

I’m really new to shaders, and I found some shaders that were just pure code…

//
// Shader: "FX/Force Field 3"
// Version: v1.0
// Written by: Thomas Phillips
//
// Anyone is free to use this shader for non-commercial or commercial projects.
//
// Description:
// Generic force field effect.
// Play with color, opacity, and rate for different effects.
// This shader has been adapted for use in particle systems.
//
 
Shader "FX/Force Field 3" {
   
Properties {
    _Color ("Color Tint", Color) = (1,1,1,1)
    _Rate ("Oscillation Rate", Range (1, 300)) = 300
}
 
SubShader {
   
    ZWrite Off
    Tags { "Queue" = "Transparent" }
    Blend One One
 
    Pass {
 
CGPROGRAM
#pragma vertex vert
#pragma fragment frag
#pragma fragmentoption ARB_fog_exp2
#include "UnityCG.cginc"
 
float4 _Color;
float _Rate;
 
struct v2f {
    V2F_POS_FOG;
    float4 texcoord : TEXCOORD0;
};
 
v2f vert (appdata_base v)
{
    v2f o;
    PositionFog( v.vertex, o.pos, o.fog );
    o.texcoord = v.texcoord;
    return o;
}
 
half4 frag (v2f i) : COLOR
{
    float3 color;
    float m;
    m = _Time[0]*_Rate + ((i.texcoord[0]+i.texcoord[1])*5000000*_Color.a*_Color.a);
    m = sin(m) * 0.5;
    color = float3(m*_Color.r, m*_Color.g, m*_Color.b);
    color *= 1 - clamp(2*distance(i.texcoord.xy, float2(0.5, 0.5)), 0, 1);
    return half4( color, 1 );
}
ENDCG
 
    }
}
Fallback "Transparent/Diffuse"
}

But I don’t know how to get it into unity. I’ve tried creating a shader and pasting the code, but I can’t put it on my sphere. Any ideas?

You need to Create a Material in Unity and assign it to use the shader you made. Then drag and drop the material into the MeshRenderer material field and you should be able to see it on your sphere.
