How to make shaders work properly with animation settings

I’m following Nolkaloid’s shockwave shader tutorial and using the Kenney Simplified Platformer player spritesheet. I’ve set the Hframe and Vframe properties on the spritesheet to 4 and 2, respectively. My shader code looks like this:

shader_type canvas_item;

uniform vec2 center;
uniform float force;

void fragment() {
    vec2 disp = normalize(UV - center) * force;
    COLOR = texture(TEXTURE, UV - disp);

When setting the center to 0.5 and the force to anything above 0, the other sprites in the spritesheet end up coming into the image. How do I fix this?

That is happening because the UV’s are going beyond the range of 0 - 1.
The easy fix is dividing the (UV - disp) by a number. How big this number is depends on the force.
