wick3dr0se / dyhra

A simple Tibia-like RPG

World

Dyhra is two-dimensional but despite that, takes advantage of isometric projection to give a three-dimensional feel. It should purvey depth and capture an immersive experience with various structures such as castles and caves. The world is filled with wildlife such as deer, wolves, bears and more. Some agressive, some not

As a player finds their way deeper into a cave, tower or the likes, they should face increasingly difficult enemies. Players will have to adventure and risk getting lost, stuck (forever) or killed. Dying in Dyhra is intended to be unforgiving and therefore a player will lose character progression, some items on hand and face other penalties

Map

Map files are created with a map editor such as Tiled, in which the capability to export as a JSON file is provided. Macroquad-tiled utilizes this JSON information to properly iterate a PNG tileset (easily made with a pixel art editor like Aseprite). Tiles are 32x32, drawn as 32x16 to give a proper alignment and stacking effect
