rgb offset shader v2

i decided to go back and fix the offset system by adding xy support to the shader

 

remember, you must credit me for using this shader

Shader code
shader_type canvas_item;
render_mode unshaded;

uniform sampler2D displace : hint_albedo;
uniform float dispAmt: hint_range(0,0.1);
uniform vec2 abberationAmtXR = vec2(0,0);
uniform vec2 abberationAmtXG =  vec2(0,0);
uniform vec2 abberationAmtXB =  vec2(0,0);

uniform float dispSize: hint_range(0.1, 2.0);
uniform float maxAlpha : hint_range(0.1,1.0);

void fragment()
{
    //displace effect
    vec4 disp = texture(displace, SCREEN_UV * dispSize);
    vec2 newUV = SCREEN_UV + disp.xy * dispAmt;
    //abberation
    COLOR.r = texture(SCREEN_TEXTURE, newUV - abberationAmtXR).r; 
    COLOR.g = texture(SCREEN_TEXTURE, newUV + abberationAmtXG).g; 
    COLOR.b = texture(SCREEN_TEXTURE, newUV + abberationAmtXB).b;
    COLOR.a = texture(SCREEN_TEXTURE, newUV).a * maxAlpha;
    }
