Detect a key pressed

At first I wanted to use that (KeyEvent, KeyDispatcher, etc.)

But StdDraw Keyboard interactions section seems much simpler

Spoiler alert : it was way easier.

How to know if the enemy is in the FoV of the player?

• You have to compute the angle between the FacingForward vector of the player and the vector between the player and the enemy. --> If that angle is less than FOV/2, then the enemy is in the FoV.

TO DO NEXT

• game over screen

• Camera ** Detect whether the asteroid is in the PLAYER FOV or not ** rotate player ** keys to move the player ** draw the enemies, while respecting the perspective ie the more it is far away the smaller it is ** highlight weak enemies

• Asteroids "handling" ** bounce on the borders ** merge/split ** be able to eat them
