Hello,
I'm wondering if there is a sort (or something) function that will compare a given value to all values in a matrix.
What I am trying to do:
I have a matrix of lines that make up the volume of a cube in 3d space. The lines are generated randomly, so I have a class StringLine that has X and Z values, and Y determines what portion of the string will be "lit up." So now I want to add a ball to this environment, in a sort of pong match, so it has float values to determine its location, but the strings are placed randomly, so I just want to find the closest one and light it up.
So if the cube is 1 x 1 x 1, and the ball is at .2 on X and .5 on Z (half way into the cube, .2 from the left) but the closest string is actually at .22 .48 or something, I want that string to get the center of the ball, and so forth. What is the best way of going about this? Does my explanation make sense?
Thanks.
