The Microsoft help is a great reference, that's all I use.rhfb said:I already have THE AI book, and I know how to code basic physics stuff, I just need a very good reference book that I can go to. I know C# and Java are somewhat similar already
Holy crap, 3 years? That's dedication. Is it finished now?djtiesto said:
Yep, the code to calculate the normal vector for each object is simple, but for improved efficiency I store that vector in the Line, Piston, Goal, Fail etc. class. In fact now that you mention it I haven't done this for Piston yet, that's another thing to do.Slavik81 said:
What about hitting the end of a line? You could deal with hitting both sides of the line using the same normal vector... but the ends aren't like that. I think you use a circular cap on line segments, but I'm unsure of how you calculate from there... The normal vector would be the radius, of course, but how do you know where in the circle that the ball hits? Per-pixel collision?The Friendly Monster said:
Almost all the way there. It's actually really simple.Slavik81 said:
if( (ball.position-circle.position).Length() < ball.radius+circle.radius )
{
normalVector = ball.position - circle.position;
normalVector.Normalize();
intersectionPoint = circle.position + circle.radius*normalVector;
//do all your collision stuff now
}Cool, are you working on anything new?djtiesto said:
I'm still working on my technology. I just finished building an object tracking structure, implementing spriteSheets and animations. As this is my first project, there's quite a lot of that sort of stuff that I have to learn and build. I look forward to when I can build a game and use my old classes.The Friendly Monster said:
The Friendly Monster said:Started up again on my first project "Plus". It's a simple rhythm game, although the rhythm isn't predefined, the player must press the right buttons, but it can be on any beat. I'm currently working on the scoring, rewarding more points for pressing on the stronger beats and penalizing for being repetitive with your rhythm. It's not much fun at the moment though, I'm not very pleased with how it's going. I'm also not planning on sharing this one around for testing since it uses copyrighted music files, also the code for getting my ps2 pad to work with it is, I'm assuming, very specific, It'd be pointless work for me to try and make it work for everyone.
Cool, sounds like a reasonably ambitious first project. The workflow you go through when doing a solo project is certainly strange. I spent about a week building a level editor for myself for pizzicati, no one is going to see that but without it I would still have only made about 10 levels. If you need any more advice on 2d physics collision detection and response then I'll try and help.Slavik81 said:
That's a cool idea, I'll definitely take a look if I decide to share it. The only caveats are that the music needs to be in 4/4 and have a steady tempo throughout, obviously this isn't ideal but it'd be a lot of work for little reward otherwise.

Try rounding them off with radius 0.Slavik81 said:
I had quite a cool "pedal" idea though...ah well I think I'll still be able to do something cool with it, I'm glad I tested this part of it out so early in execution.Ghost said:
It's a laptop, kind of defeats the purpose. Plus if I have it then someone else will, so that's the limitation I'm going to have to stick to. It's only a few combinations where three keys don't work, you can get like 8 keys if you press the right ones.Ghost said:I had that problem a while ago, ninge (gaffer) told me the standard solution was to think of keys as 'swtiches' rather than 'peddles'.
Ive never seen 2 key only though...time to invest in a USB keyboard
I think I need to round it a little more than that to get my normal collision animation to look acceptable.The Friendly Monster said:
I think thats probably fine,Slavik81 said:
Is it meant to be realistic physics, because in that case you may want to call the physics update more than the 60 times a second which the draw update is called. In pizzicati the physics engine is called 500 times a second, probably overkill but the higher this is the more realistic collisions will be. Do this with
Not realistic at all. The gameplay deals with a bouncing ball. The idea being that whenever you hit something, you stick to it for a second... During that time, you have heightened control over your movement. I figured it would be an interesting way of doing platforming.The Friendly Monster said:
Sounds cool, are you bouncing off straight lines then? If you are in need of a performance boost I think my line collision algorithms are fairly good. I'm not going to get anything done this weekend with the football and cooking for friends and relatives.Slavik81 said:
I'm guessing you're using XNA. Personally I'm an advocate of diving straight in and dealing with problems when you get to them.snack said:
Sorry I can't help here, I've only used 2D XNA.godhandiscen said:
penGL. Deadrock is all my own work though. It's still in very early stages, but here's a screenshot anyway.
I checked out your game, it's cool, 11 people sounds like a bloody nightmare to manage. I liked the theme of being inside the body, reminds me of a book I had when I was a child called "the magic school bus". One thing which I thought would be nice would be to have a little more animation, maybe little thrusters on the back of the ship or slightly different sprites for the different directions you're moving. Also the hitbox is quite big for the main ship, there are times when the bullets hit you when they don't seem to intersect the visual body of the ship. Maybe a circular hitbox would be more appropriate.Slavik81 said:
Thanks, I agree with you entirely. I was actually hoping to add particle effects for the ship's thrusters and finesse the level design/gameplay/control, but as the project is due tomorrow I really have to work on my documentation instead.The Friendly Monster said:
Ok, what documentation are you required to include? Complete design doc?Slavik81 said:
I'd say I found the game a fair difficulty, I got past the first boss and then started messing around pushing the game around to try and find out how big the bounding box was, how big movements felt etc, I died pretty soon after that and didn't feel like playing through again straightaway. Might have another look later.
Yeah it's totally eye-opening to see people play your game, my sister tried out pizzicati for the first time yesterday and couldn't understand what she was controlling without me telling her.

Awesome, I'll send you off my code for the other game I was working on and beg you to help me out with my glitchy collision detection. I'm not sure how I could improve it, other than by increasing the frequency of the collision checks such that the player cannot travel fast enough that he passes through and touch two bounding boxes and into another between checks. I'm thinking that in the case that the player overlaps multiple bounding boxes, that he should be sucked backwards to where he was at the beginning of the frame one pixel at a time, while checking collisions until he's no longer touching a bounding box... then the last bounding box he touched was the one he hit first.The Friendly Monster said:
googlepages is awesome. I was looking into buying a domain etc. but decided it was too much cost/hassle to be worth it when I can have google host my stuff for free. You can also make html websites and just upload them as files. see gilescoope.googlepages.com for an example (not the frontpage though). Yours looks good though.Slavik81 said:
Cool, what kind of music are you looking for?Sylar said:I'll be revealing my game very shortly...just looking for music in master form. So hard to find
As in, you need every instrument separated? Or you need the higher quality? Also does the music need to be recorded rather than synthesized? You'd have a much easier time looking for midi (+ vst plugin) arrangements than an actual multitrack digital recording.Sylar said:Anything really, probably something lower tempo-ed but the big thing needed is master tracks
