it looks like a good class , but i've got a few problems... : First of all i dunno what a vector is? then i dunno what the function normalize and setangle do? HELP!!! |

a vector can be thought of in this case as an objects x and y speeds and thus its direction seting the angle change the speed so that the object would go in the direction of the angle normalizing reduce the vector down to a size of 1 (still move in the same direction. except slower |

aaaaaaah... i c i've done that in a different method i used boards friction to reduce the speed of ball but i still think yer method is better =/ |

ok now i understand but which one of the procedures in the class actually moves the vector? |

you dont move the vector, its used to move another object |

i think there's a tutorial around here on how to use classes... its that thing where you go ClassName -> procedure |
