It's an idea I've had for a few years but never got around to making it. Vertically scrolling Bullet hell with Crystal Quest (and PC clone X-Quest)-style mouse control (弾幕 と マウス ?).

I'm not quite sure how it'll work out but I've got a feeling that there's some precision missile-dodging fun to be had...

I rather liked Riesling, so I'm looking forward to another shooter from you.

Hopefully I can make it a bit more immediately accessible - the problem with Riesling is that people don't neccessarily realise that the nearest background layer provides the crucial visual cues to show how fast your ship is moving. I think it would have worked better from a gameplay perspective to have a single background layer which fills the screen so the neccessary visual feedback would be more apparent.

Anyways, I've made a start on the basic "engine" - it'll be made in PureBasic, but I'm using IDirect3DDevice7::DrawPrimitive() directly with an array of D3DTLVERTEX instead of relying on PureBasic's built in sprite functions (if you're familiar with Blitz3D this is basically for the same performace reasons as using a "single-surface" sprite system)

OK my sprite engine is pretty much done - here's a test featuring 2048 invaders with random rotation, color and alpha. Resolution is 800x600x32: sprite_test.zip



So far it has been tested on Geforce 6600, Geforce 3 ti200, GeForce FX Go5700 and ATI Mobility Radeon X300 - if you have a different graphics card please try it out and let me know if it works.

It gave me about 40 fps on my Thinkpad X40, equipped with an Intel Integrated Graphics chip.

It's all about the GPU's fillrate in this demo.

hmph...I've been battling with compatibility problems with a Dell Latitude with Intel 945GM Chipset - nothing is displayed.  It's frustrating because Purebasic's native Direct3d alpha-blended sprite commands work fine... I have no idea what I'm doing differently - and I've got no idea where to look or who to ask for the solution.

I've decided that I hate DirectX 7 - why doesn't it work the same on any graphics card that claims DirectX 7 support? I don't understand why Microsoft didn't say to the graphics accelerator manufacturers: "This is the DirectX 7 specification, your hardware *must* support these features exactly".  (Apparently with DX10 everything will work as expected..but it's going to be a while until everyone is using Vista on a PC.)

Anyway...I've had enough of trying to figure out what's wrong with my sprite engine for the time being because it's eroding my enthusiasm for this project...I'll get on with making the game and maybe come back to compatibilty problems later.

Hi, this is my first post here!

The demo runs at around 262 FPS on my Radeon 9600, 256 MB. Very smooth animation!

Very smooth animation!

That's due to positioning the sprites with sub-pixel accuracy...it can't be done with native PureBasic sprite functions so I'm pleased that I went to the trouble of figuring out the Direct3D way of doing things - it also means my engine is resolution-independant which is a bonus (although 32 bit color-depth will be a requirement, so I don't think Voodoo3 cards are supported).


As for progress update - I've coded the menus, high score entry + loading and saving of .ini file.

Also I dug out my ancient Wacom 2 tablet (luckily my machine has a retro RS-232 Serial port) and made a bitmap font:

The Crystal Quest remake for XBLA is indeed a fun game (although I dont like the colors in it) - Actually I like your title screen better then their XBLA one.  But at any rate, its a shame we didnt see this one finish.  If you do work on it again, let us know
