Quilly Crawler

Quilly Crawler will become a small dungeon crawler game with a round based fighting system using Kotlin and LibGDX. It uses other open source libraries like LibKTX, Ashley, Gdx-AI, Box2D or Gdx-Controllers.

Until it is finished, I will stream every weekend on twitch. Also, a VLog will be uploaded every sunday on my YouTube channel. If you are interested, please feel free to subscribe :)

About the game

Quilly Crawler is a dungeon crawler game where you play an old man and go deeper and deeper into an endless cave. Every level contains enemies that you can fight, chests that you can loot, a shop to buy and sell items and a reaper who can set you back in the dungeon if it gets too hard.

The combat is a round based system where every entity is executing a single order per turn. The order is defined by the agility of an entity. As a player you can either attack, use an ability or use an item. There are offensive abilities like a Firebolt but also defensive abilities like a Heal or Protection ability. In addition some abilities will add a buff like the Protes ability which reduces physical damage by 50% for three turns.

I have only added a few levels, enemies and items to the game. Feel free to fork this project and add your own content. If you have any questions, don't hesitate to ask and use the Discussions for it.

quilly-crawler's Issues

Outline Shader textureSize function does not work on some machines

vec2 pixelSize = 1.0 / textureSize(u_texture, 0).xy;

Exception in thread "main" com.badlogic.gdx.utils.GdxRuntimeException: Could not compile shader 'commonsOutlineShader': Fragment shader:
0(16) : error C7532: global function textureSize requires "#version 130" or later
0(16) : error C7011: implicit cast from "ivec2" to "vec2"

Workaround would be sending the texture size as uniform but we need to be careful as this is requiring a flush and therefore it should be ideally only happen once per frame / texture binding.

UI Lists are not scrollable and Single-Target Commands for player entities cannot be cast on self

refer to image below:

• abilities should be scrollable and always within the tables content area. This fix also needs to be applied to the InventoryView
• Heal is selected which can only be cast on enemies. The AI is correctly casting it on allies since it is a Defensive/Supportive Command but the CombatUI doesn't support that. We should check if it is a Defensive/Supportive ability and then allow the selection of a player entity. If it is only one then the selection is not needed and it can be cast immediatly
