I primarily program in C++ and Java. Recently I started learning Haskell. My current mathematical interests are group theory, graph theory, category theory, and type theory.

Java Collision Detection of a Slope using a Gradient I feel stupid for not noticing that. I have encountered similar round-off/truncation errors in my graphics programming. |

Java Collision Detection of a Slope using a Gradient Thanks for the edit and update. I don't see a problem with the code you have given. Can you post a SSSCE to give us a better idea of the problem? |

Java Collision Detection of a Slope using a Gradient If the line slopes from the top left to the bottom right of the screen, then you have calculated m correctly with m = getHeight() / getWidth();. You should not later change m with the *= assignment operator, as far as I can tell. I suggest using just y = m * ball.x + c; in the line under discussion. |

Java Collision Detection of a Slope using a Gradient The orientation of the Y axis shouldn't matter as far as the calculations are concerned. This only becomes a factor when you plot to the screen. I have one concern about the line slopeY = m *= ball.x + c;: Is there a reason for the *= in there? It seems to me that it should just be *. |

How does one escape the GPL? I don't know if a LOL deserves a +1 or not... |
