Gamedev Challenge - Shooter with no weapons The requirement is to create a horizontally scrolling shooter game with no weapons. I thought that I could have the enemies shooting at you and you could use their own bullets against them. If you had a shield, you could reflect the bullets back. I created a quick demo and generated some bullets. The first problem was how to work out which direction to bounce the bullets back. After a bit of tinkering I found the best way was this - 1) Get the direction between the playerx,y and the bulletx,y 2) Invert this (add 180 degrees) I tested out and it works OK, I think. Note that in the video, the bullets don't just get bounced in the opposite direction they are travelling, with a bit of skill you can actually 'aim' the bullets towards different parts of the screen, depending on where they hit your shield. A nice demo, but can I turn it into a game???!! https://ift.tt/eA8V8J
