Bullet hell (Touhou) fangame

[SuperV1234]

I've only been using SFML since a day and I've already started an ambitious project. It's a Touhou fangame. Touhou is a bullet hell game, a shoot'em up focused on dodging a lot of bullets. Here's a video of my progress for now.



Anyone interested in giving an hand?

I'm planning to make boss battles non-hardcoded, instead scripted in external .lua files that are loaded using LuaInterface.

Oh, the project is written in C#, not C++.

Why don't you try to use already existing Touhou editor like Touhou Danmafuku? =p

Oh, I use Danmakufu a lot. I created 2 boss battles, and released them on Shrinemaiden.

However it is very limited.

What I am trying to create will be much more flexible than Danmakufu, I hope.

Here's a new video.

Hey, did you know you got a concept here? Instead of playing Reimu as always, make the player play a boss, with her own spellcards, and the player must defeat reimu controlled by the CPU. :]

Anyway, good luck for your project!

That sounds cool! However I think I could create a 2-player mode (maybe over the internet) where a player draws danmaku with his mouse, and the other one dodges.

Or maybe a script editor that "records" your mouse movements and creates a script that does the same thing. The possibilities are endless! :p

What did you used for the white bullets? Simple image with transparency or some rendering tricks?

I used BlendMode.Add.

Anyway I have a big problem: I implemented LuaInterface to create bullet patterns, and it's working. However, I can't manage to find a way to make the program "wait" for some frames. Here's my Lua script:

luanet.load_assembly("SFMLTouhou");

for k=1,32 do
   for i=1,32 do
      CreateBullet(200, 200, 11.25 * i + k, 5);
      Wait(100);
   end
end

The "Wait" function currently does nothing. How can I make my script just wait some frames then continue, without obviously stopping the player and the rest of the game?

[Spidyy]

I figured out after asking for the Blend::Add. :/ Now I have a reason to use this option. :p

For the wait thing, I don't know how to use Lua, but can't you code it in your C# class, like adding a wait timer in your bullet generator?

[SuperV1234]

I can't figure out how to do it. Can you make an example?

---

Nevermind, I found a solution.

I have another problem now: creating a large amount of bullets at the same time slows down the game a lot. After they're created however the FPS is back to 60.

What can I do to prevent this?

[Spidyy]

Huh it can come from many thing, but you can do some optimizations.

The most common is to create a simple array of bullet and use a bool to set them alive/dead when you need/don't need them, instead of creating new bullet each time you need to add one (with new/delete).

I know there is another way to display bullet more efficiently but I never tried it.

If you didn't already done it, go see on www.shmup-dev.com, there is one or two tutorials to optimize your bullet engine.

[SuperV1234]

Thanks. I made big progress today.

Successfully implemented LUA scripting. Look at these two videos (and read the first one's description).

What are the strange green circle inside the bullet that appear time to time? Hitbox? :s

Looks pretty nice though!

Yes, those are the hitboxes.

Thanks!

Neat.  I'm also doing a Shmup, though wanna do my own twist on things.  I'm in the process of trying to figure out a good way to get enemies to get loaded in from a file properly.  I'd like to know how you got the blue glowing effects on things.  The whole graphic side of this concerns me.
