The Void calls for you.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A recreation of UNDERTALE's battle system entirely in unmodded Minecraft complete with a FULL boss fight!
ONLY FOR JAVA 1.21.2 - 1.21.4
(Recommended 1.21.4. Use 1.21.2 & 1.21.3 at your own risk)

Ever wanted to play UNDERTALE in Minecraft? No, I doubt it, but I'm sure you'll LV this!
You're pitted up against Gaster, the man who throws speaks in hands. Not really sure why, but he really didn't want to stay in his world, so he's brought it to yours. He knows what you and many others have done. After all, Minecraft is a world where killing monsters is normal. Will the power of LOVE prevail? Or will echoes of the past haunt you forevermore?

I'd recommend for the first fight like a checkpoint for the final attack, but so far things are well made, good job.

Icredible map, the attacks are good and not stupidly hard, I'l only complain about the final attack feeling more like a diff spike for epicness than anything but else it's great!

This also just teaches me that much more can be done with datapacks and ressources packs. (And that you can stick a ressource pack into a map file, I'l make sure to do that for my project(s))

Looking at the map in spectator is so cool, it's not JUST datapack, there's also a s***ton of commandblocks that as we know only the person who made them will ever know how to use em.

Tip: you can add this very simple shader to your resource pack under /assets/minecraft/shaders/core/rendertype_text.fsh to stop fade ins/fade outs from ending very abruptly

#version 150

#moj_import <minecraft:fog.glsl>

uniform sampler2D Sampler0;

uniform vec4 ColorModulator;
uniform float FogStart;
uniform float FogEnd;
uniform vec4 FogColor;

in float vertexDistance;
in vec4 vertexColor;
in vec2 texCoord0;

out vec4 fragColor;

void main() {
vec4 color = texture(Sampler0, texCoord0) * vertexColor * ColorModulator;
if (color.a < 0.00001) {
discard;
}
fragColor = linear_fog(color, vertexDistance, FogStart, FogEnd, FogColor);
}

Bro, make a checkpoint in the middle of the battle because it`s starting to get incredibly annoying to start over.

there is no reason to add checkpoints, as it is already of fairly low difficulty. stay calm. stay determined. learn the patterns. only then should you succeed.
