Very nice - No sound;=<
in your project description you should have a link to the next part to make navigation easier
I'm confused. How is it a direction? a direction is a trigonometrical number, isn't it?
Angle is a trigonometric number, it represents a difference in rotation. If you have a reference rotation position then it can denote direction. The vector denotes both direction and distance.
(view all replies)I hate math too, but I'm gettin' good at it. "Zis project ees very good!
my head hurts. i don't like math
Not really. A slope normally only denotes direction and is normally calculated as dy/dx. A vector is the set [dx,dy] for 2D or [dx,dy,dz] for 3D.
isn't this a slope?
does it show a direction?
What does the vector do?
I don't think so,
So there sprite at x:-20 and y:-20, and another at x:20 and y:20. To find the exact place between them,you do for x: -20 - -20=0 and y: 20 - 20=0. So the distance between them is vector, and vector is the place of two points. Right?
thanks for your time making this to help everyone

Ohhh... nevermind.
Isn't a vector also called a ray?
