hi all, i am new here, have a project to accomplish.. i have written a camera and a player class where each generate camera and player.. i want my camera to follow the man where i cannot yet move the man in the direction he looks.. more precisely: i want to move the man where ever he is facing.. i can move him in x or other directions but cannot move him where he faces.. i can move the camera around but cannot make it follow the man.. what shall i do in order to make these work? tnx

well the man is facing [0.0,0.0,-1.0] i mean to -z direction..
how can i show this as a vector?
i am quite not familier with these vectors..
how can i learn how to use vectors? do you know some tutorial or very simple sample code for me to look and see?
thank you by the way.. it was a quick answer..

this is my favorite 3D math quick reference page:
http://www.geocities.com/SiliconValley/2151/math3d.html

for more in depth tutorials on 3D math (Linear Algebra) look in the Articles & Resources section of this site under the Math section. and just FYI, [0,0,-1,0] _is_ a vector. a vector is just a direction in 3-space. but read the tutorials and it will make more sense.
