So I did not finish my game, it's more kind of a tech demo. It was a extremely busy fortnight for me, and I spent the last week doing something essential but time consuming... building a runtime setup for distribution. I've been working on getting my slightly strange platform and requirements building on Mac OSX and ran into some problems with packages and leopard and stuff. I managed to get it running, but I'm still trying to coax py2app to build me a distributable. I'll upload a build file once it's done, but it won't be much.
Next gamejam, once I have this build out of the road, my journey should be much smoother. Each gamejam will be an attempt to incrementally improve the development chain.
Now on to playing other peoples gamejam entries!

One major task was to get fonts working. I'm using SDL to render a TTF file to an OpenGL texture, and then rendering that on screen with quads. There was a weird bug I tracked down where I was uploading all the textures to the graphics memory upside down and I'd been doing it all along with the sprites! But because I was also drawing the quads upside down with the sprites it cancelled out and I didn't notice. I did notice with font code where I introduced new routines. Funny how you can go for so long before you realise you are actually doing it upside down!
I added a red navigation arrow that always points to some absolute coordinate in the level. I am planning on using it as a navigation aid between sublevels, to help differentiate the game from the time pilot line clone. Instead of just an endless onslaught of enemy, and having to shoot so many to go on, the level is comprised of "go here and shoot these, then go here and shoot these".
Added the first steering boid and gave it some public domain 1942 clone artwork. It'll do for now. I really need to get more that just clouds going as a background...

Implemented shootable urchins. Simple N x M check. Simple distance between centre points test as collision test. Not scalable, but runs at full FPS with 64 cloud objects, 32 urchins and about 5 bullets max. Any more and it starts dropping frames. So 32x5=160 checks per frame. Not ideal, but certainly very very easy to implement. If it becomes a problem later I could do a dirty quad-tree or something, but I honestly don't think it'll be an issue. Its only two weeks!
Explosions! Oh the pain of the explosion sprite. I cant draw. Found a free explosion sprite but it was unanimated, but looked nice. So I added frames around it in Gimp and sized it down before the frame and dispersed it later. Thus turning 1 frame into a passable explosion! Good explosions are so necessary!
Set up an array of 32 spinning drones at the level start. Its a lot of fun to shoot them. The player ship collision isn't done yet, but you can see how it will be tricky navigating. It's pretty much turning out to be a straight "Time Pilot" rip. It has that same constant speed, turning arc calculating kind of piloting. But maybe I'll add some new angle on it or something to make it interesting.
Wish I could spend more time on this. But commitments get in the way. A good effort next weekend should polish it up good. Fonts... have to start thinking about fonts...
Ship Control and Shoot [ view post ]

Got the clouds moving parallax. Rotatable ship at the middle instead of urchin. Made the clouds move opposite to ship direction. Added fire function with some bullets. And there's a strange bug. Certain textures render as blank white squares. And changing arbitrary things change which texture is affected. Have to get to the bottom of this one.

Lets see. Get window up and going and load in the asset. ok. thats working good. Testing sprite rotation, movement, scaling and alpha. Playing with some moving alpha'd sprite I tried the "obscured by clouds" effect a bit like that on Mario. I uploaded a grab. I have an idea. That's all I got for tonight. Sleep time.

Woah the cloudage rocks. Nice work!

Cool!, the new clouds add a lot.

Looks cool, I bet those urchins are real satisfying to pop.

this is looking total like time pilots! and thank for the nice comments!

RE: explosions...
You could try simply scaling up a sprite from 0 scale, while fading it to alpha. Works great, esp with circular shock wave style explosions, with alpha fading at the edges.

w00t! Hoorary for GL alpha blending!
