Danmaku no Kyojin
Danmaku no Kyojin (弾幕の巨人) is a 2D danmaku developed in C# with XNA.
Project ideas
- An arena shooter with danmaku like bullet patterns
- Boss wave only (no "Campaign", just a survival mode exclusively composed of boss increasingly large)
- 4 difficulty modes (Easy, Normal, Hard, Impossible)
- Control a ship with keyboard (moving + slow mode) and mouse (shoot + bullet time) or with a gamepad
- Boss creation using procedural generation
- Local and online multiplayer (cooperation with scoring race)
- Bullet time mode (time is slowed except for player(s))
- Simple sprites (geometric) but heavy use of shaders (kikoo effects)
- Bounded area but 2D camera (game area is not limited to the screen size)
- Scriptable bullet patterns (BulletML)
- Steam publication forecast
Inspiration
Touhou Project
For its danmaku/bullet hell aspect (complex bullet patterns) and its incredible difficulty.
Warning Forever
For its idea of figthing a single enemy that become stronger each time we beat it.
Geometry Wars
For its bloomy visual and particle effects.
Current state
- The player controls a ship and can shoot multiple bullets
- Boss procedural generation works and its size can grow at any time
- Bosses can be splitted in 2 parts and its total life depends on the number of its remaining portion
- Simple particle engine
- Bloom effect
TODO List
- Port the game from XNA 4.0 to MonoGame 3.4
- Add random set of turrets to each boss
- Basic turret: fires a simple bullet to player's position
- Shootgun turret: fires multiple bullets to player's position
- Laser turret: fires a laser to player's position
- Homing turret: fires homing missiles
- When the boss splits in 2 parts, the part that comes off must act independently
- Add an outline effect around boss shape
- Bosses are static, add some random movments
- The camera's motion is not optimal to avoid bullets
- Tweak it to have something similar to Geometry Wars one
- Add a focus button that slow down the player's speed and zoom on player's target
- Add Steam API support
- Online multiplayer (coop)
