lol, thats old school

the vecx and vecy are used in mostly movement scripts

NPC Code:



vecx          vecy         dir

0               -1             0

-1              0              1

0               1              2

1               0              3

when you move, then it basically does this
playerx+=vecx(playerdir);
playery+=vecy(playerdir);

so if you move up (dir 0), you will get 0 added to your x value, and -1 added to your y value

We learned something stupid like that in school.. There is the axis thing, its like the big DOT in the middle. the left side is the X and the right is the Y, I think. And you would write the answers to the problems like (0,3) and stuff.. Its freaky.

0 = axis
3 = y

If it were -3, I think it would be X.. im not sure *cries* I hate math

its called a grid

NPC Code:



         Y   (+)

         |

         |

(-)      |       (+)

X--------|------ X

         |

         |

         |

         Y  (-)

with the (0,3)

you would move 0 spaces on the x axis and 3 on the Y axis, which is equal to up :)

lol :p

it's called a cartesian plane, or coordinate plane....they're a lot more fun to play with in Calculus, trust me ;-)

NPC Code:

 Input  vecx  vecy

  0      0    -1

  1      -1    0

  2      0     1

  3      1     0
