I have tried reversing the players movement which is this.
PHP Code:
player.x -= sin(this.angle) * this.speed;
player.y -= cos(this.angle) * this.speed;
But that doesn't work.
I think I'm in way over my head. |
That won't reverse the direction in which the player moves, instead do what chris said and just add pi to the existing angle.

I meant variable wise, you're going to keep on adding onto your angle which will eventually become quite a large number if used for a while. Also while you do have a valid point I'm sure one extra mod and multiplication operator doesn't effect performance to the point where you'd notice on any machine. What if I wanted to see what was going on in the script and I had some huge messy number as the angle, it'd be pretty ugly to work with. Also by including mod and multiplication the angle can work with other formulas if you choose.
Also for those who don't know % is the mod operator. It works by spitting out the remainder of 2 given numbers. Eg:6%4=2, 6%5=1, 11%10=1
