Greetings, all. This is my first post. Hello all. I take this as a chance to introduce myself to the community. Very concisely, Phillip, 26, a degree in the game development, computer engineer, started Unity 5 months back. I'm looking forward to meeting lots and lots of cool guys and girls to exchange ideas and become friends. On-topic: I'm making a game in Unity, 2D. I'm having trouble with understanding Vectors. I have three points in the world. A: Player, B: Player Gun, C: Point of the mouse location I get these are all represented by vectors. The expected: I click somewhere on the screen (C) to spawn a projectile at location of a gun (B) with direction from player to mouse location (A). The Problem: I did some debuggin' and projectile's vector of direction says (-9, 5.5). Assumably, the projectile would move in UP and LEFT direction. But, it goes down left.. what looks like ~(-9i, -1j) What am I doing wrong, and how can I help you help me? All answers welcome.
