Steering question - arrive at angle?
|
Hi everyone,
I'm trying to tackle a problem I thought would be straight forward but turn out to be quite a headache. I'm trying to simulate a car switching lanes, and want the motion to be as natural as possible. The player does not control the car'... |

How'd they do it?

Hi everyone,
I've been playing World of goo for the last couple of days and I'm pretty fascinated by the art style they've used.
I especially like what seems like a simple effect that I don't know how to achieve - when you move the mouse curso... |

Locating a line of code by memory address (at run time)
|
Hi everyone,
I have a pretty straight forward question (I think...)
I have a memory address I know is causing a program crash, and I would like the debugger to take me to that line of code during runtime. Is that possible?
If so how? I am using C+... |

I have a basic "floor" shape and body as seen in the moon buggy tutorial which is totally horizontal and flat.
Balls are bouncing from the top of the screen to... |

Loco roco / Gish kind dynamic shapes

Hi everyone,
I'm very interested in spring physics and collision detection, and I was wondering how I can achieve a loco roco (or Gish, if anyone knows that game) kind of dynamic shapes. Basically, the simulation is of a "goo" like form that bounces... |

Analog stick values not smoothly changed

Hi everyone,
I'm writing a game in c++ that's using directInput for gamepad support.
I want the right analog stick to be used as a unit circle (simply an x
& y vector between -1 and 1).
I am using the DIPROPRANGE struct with SetProperty to se... |

Steering question - arrive at angle?
|
It is too advanced I'm afraid. Thanks for the in depth reply and your assistance so far :)
I'm actually making progress on my own and may provide a solution if I can make it work well. I'd still appreciate any help/advice from others though.

i'm sorry, but I'm afraid I'm not familiar with the theory behind the car model I'm using. Here's the reference code I'm using:

I actually spoke to one of the developers. It's exactly as you suggested dmatter, scaled circles of different color.
I can't believe it's so simple - I was sure it was a lot more complicated :)
Thanks guys! |

So I guess my question is can this be achieved with simple sprites, or do you need some sort of shader to stroke the outlines like they do? I may be blabbering completely here, so if someone can point me at the right direction at achieving something... |

That's what I was thinking at first too, but notice how smooth the outlines are.
i'm guessing if it was small circles one after the other, you would have seen roundness in the outlining? I'm playing around trying to achieve it, so far no luck :... |

Never mind - I mixed up by ref parameters and pointers. all i need to do was change the decleration to a real by ref one and it worked :) |

Loco roco / Gish kind dynamic shapes

JB - What algorithm did you use to calculate the outline? it doesn't sound easy ;)
How can I calculate the new outline tangentially as fingers suggested? |

Yep, I think that'll do the trick...
I still have a feeling itwon't look as good as I imagine it though.
I'll give it a try soon and keep you posted - thanks for your suggestions!

Loco roco / Gish kind dynamic shapes

I just realised it doesn't solve the collision detection problem - just the bouncy/gooey part of it. You still have to find a way to make the blob collide realisticly with other objects (without "floating" near them as JBourrie suggested)... collisio... |

Hmmm... that's a really cool idea. simple and elegant - I'm gonna try a bit see if I can get it right. BTW - how does metaballs work? is it really that simple? |
