DISCLAIMER: This thing isn't completely finished! It might (will) be very buggy!

Danmaku Engine is a C plugin for Godot I write and use to make my SHMUP games. It's geared towards my workflow but it may be useful to you too!

At the moment the plugin can handle ~6000 simultaneous bullets before it starts to hang (though it can always be more performant and I'm always looking for more ways to squeeze more FPS out of this thing).

I've spent time researching, and much more time playing, great SHMUPs such as Touhou, DoDonPachi and Blue Revolver, and I have tried my best to develop this plugin so that you can create amazing bullet patterns at that level.

• Bullets! Lots of them!
• A bullet emitter node.
• BulletSettings that you can save and reuse.
• BulletPattern resource.
• (coming soon!) Seeded randomisation for deterministic emitting. #replays

To get started, create a BulletPool node in your scene and set how many bullets you want the pool to... pool. Make sure you set correctly as the node will never activate more bullets than exists within the pool.

To spawn bullets, you can either do so by first creating a BulletSettings resource, then using the Emitter2D node to emit bullets for you.

Alternatively, you can do it manually:

var bullet: Bullet2D = pool.get_bullet()
bullet.start(relevant, parameters, go, here)

Once a bullet is emitted, it will have the physics layer that you set it to. Add a hitbox to your enemies/player with the matching collision mask, then connect the body_shape_entered signal to do whatever you want when something is hit with a bullet.

Probably infinite (although countably infinite). However, the distant screams of Godot running this thing is not a bug. It's a feature.

If your game crashes because of this, feel free to let me know, making sure you give me as much juicy detail as possible.

• Q: Will you be making 3D versions of the nodes?

  • A: Since this plugin is what I use when developing SHMUPs, it depends on whether or not I make a 3D SHMUP.

• Q: Can you recommend me a SHMUP to play?

  • A: Play Like Dreamer, or any of Outside's other games!
