enables you to work out how far along the line to go.
Your calculation of t is correct.
Yes, it is correct to deal with the x coordinates and the y coordinates separately like that.
So, ..... not so much of a failure after all.
(x1,y1) + t(x2-x1,y2-y1)
That was extremely helpful for my game project I am doing, so glad I found this explanation thank you!! :D
Let's say that point A is (a,b) and point C is (c,d).
I have tried to solve this problem for a while now, and I always seem to get the wrong answer. I really need help.
