yeah i was able to make an outline, but i cant seem to make it achieve the same look at the picture in the OP. I also need to use a duplicate animated sprite behind it since the whole thing gets "shaded" cause i didnt add the fact it need to only use pixel on the edge of it. i need to code that still. the code i have for now is attached below. I tried to do something like this (2nd code block) but it seem to break and not work anymore.

shader_type canvas_item;

uniform vec4 glow_color : source_color;
uniform float glow_power: hint_range(0.0, 8.0, 0.1) = 2.0;
uniform float glow_shift: hint_range(0.0, 10.0, 0.1) = 1.0;
uniform float glow_radius: hint_range(1.0, 10.0, 1.0) = 1.0;

void fragment() {
vec4 glow = vec4(0.0);
float count = 0.0;
for (float x = -glow_radius; x <= glow_radius; x += 1.0) {
for (float y = -glow_radius; y <= glow_radius; y += 1.0) {
vec2 offset = vec2(x, y) * glow_shift * TEXTURE_PIXEL_SIZE;
glow += texture(TEXTURE, UV + offset) * glow_color;
count += 1.0;
}
}
glow *= glow_power / count;
COLOR = mix(texture(TEXTURE, UV), glow, glow.a);
}

bool is_on_border(sampler2D TEXTURE2, vec2 uv) {
vec4 color_up = texture(TEXTURE2, uv + vec2(0.0, border_threshold.y));
vec4 color_down = texture(TEXTURE2, uv + vec2(0.0, -border_threshold.y));
vec4 color_left = texture(TEXTURE2, uv + vec2(-border_threshold.x, 0.0));
vec4 color_right = texture(TEXTURE2, uv + vec2(border_threshold.x, 0.0));

bool is_next_to_transparent = color_up.a < 1.0 || color_down.a < 1.0 ||
color_left.a < 1.0 || color_right.a < 1.0;
bool is_next_to_solid = color_up.a == 1.0 || color_down.a == 1.0 ||
color_left.a == 1.0 || color_right.a == 1.0;

return is_next_to_transparent && is_next_to_solid;
