Happy New Year....big deal, it looks and feels just like the old year to me! You call this the future??!! hahaha I know there has to be a way to represent velocity vectors on the computer. I can figure out how to construct a vector from an (x,y) position, but getting them "tip to tail" so I can collide two objects I can't figure out. I want to get two objects (one of them can be standing still, but usually both are in motion) to respond properly when they collide. How can I represent their motions with vectors and get them to bounce off eachother so it looks correct? The objects have mass, BTW, and I think that is somewhere in the math...it wouldn't be a problem to include the masses of the objects. But how do I represent vectors on the computer and add/subtract them to get a results of the collision of two vectors? Both objects are going to bounce off eachother, how can this be done properly? I'm not after 100% precision, but I at least want it to look right 98% of the time. Perhaps directions to code already written, or a tutorial, or something like that? Thanks.
