ZA WARUDO shockwave effect

base shader used: https://godotshaders.com/shader/distortion/

yes i dont know gdshader code so i chatgpt’d it

but its cool so im uploading it

you can now adjust the position and has inverts anything within the radius

version without invert but with adjustable position:
