Changed the enemy file so that it has functions to make it update its position or make it disappear from the screen. The floors h file includes the enemy, and depending on its position it updates it or not.

el17m2h 29:15e9640646b7 52 @details The function checks the current velocity of the doodler and depending on its direction
el17m2h 29:15e9640646b7 53 (positive or negative) it will decide if the doodler's updated velocity will remain the same or
el17m2h 29:15e9640646b7 54 change direction (jump). If the velocity is positive, it means it is currently jumping, so it
el17m2h 29:15e9640646b7 55 should continue doing so but in a decreasing velocity (decelerating), which is why it is
el17m2h 29:15e9640646b7 56 multiplied times the _up constant (value less than 1). If the velocity is negative it means
el17m2h 29:15e9640646b7 57 it is falling downwards and increasing in velocity (accelerating). This is done by multiplying the
el17m2h 29:15e9640646b7 58 current velocity by the gravity constant value (greater than 1). Finally, if the velocity is 0, it
el17m2h 26:d16a5b1e0ace 59 means it has completely decelerated upwards and so it should begin to fall. To do so, the velocity
el17m2h 25:f122e1862cd1 60 is given the value of gravity (which is a positive value).
