/**** 
* GAME DESCRIPTION:
* Game Principle:
	* NAME: COCO MONKEY V1.0 by Dalhem 2024
	* -There is beach where people are enjoying the sun by the shadow of palm trees.
	* -Above them, three palm trees are growing coconuts.
	* -In the trees, a monkey is throwing coconuts from the top of the trees, thus three points of departure.
	* -The player controls a guy who holding a parasol to protect everyone from the coconuts.
	* -The coconuts are falling at a regular speed, falling in straight lines.
	* -If a coconut touches the parasol, the player earns points.
	* -If a coconut touches the ground, the player loses a life.
	* -The game is over when the player has no more lives.
* Game Areas:
	* The screen is divided into 3 main zones in the following descending order:
		1. Score area: displays the player's score.
		2. The main game area: where the game takes place, it is divided into 3 zones corresponding to the 3 points of departure of the coconuts :
			* The left zone: the coconuts fall from the left tree.
			* The center zone: the coconuts fall from the center tree.
			* The right zone: the coconuts fall from the right tree.
		3. Options area (or advertisement).
* Game Progression:
	* At the beginning of the game, the player has 0 points.
	* The player has 3 lives.
	* The player can move the parasol by dragging it.
	* The monkey throws coconuts at a regular interval randomly from the top of the trees.
	* When a coconut touches the parasol, it bounces up following a parabolic trajectory.
	* The parabolic trajectory depends on the angle of the parasol:
		* The more the parasol is inclined, the more the coconut will bounce back :
			* If the parasol is in the left zone, the coconut may bounce following a parabolic trajectory :
				* to the left, thus outside the screen.
				* to the right, thus towards the center zone.
				* to the extrem right, thus towards the right zone.
			* If the parasol is in the center zone, the coconut may bounce following a parabolic trajectory :
				* to the left, thus towards the left zone.
				* to the extrem left, thus outside the screen.
				* to the right, thus towards the right zone.
				* to the extrem right, thus outside the screen.
			* If the parasol is in the right zone, the coconut may bounce following a parabolic trajectory :
				* to the left, thus towards the center zone.
				* to the extrem left, thus towards the left zone.
				* to the right, thus outside the screen.
	* the parasol has three zones of influence:
		* The left zone: the coconut will bounce to the extrem left.
		* The center zone: the coconut will randomly bounce to the left or to the right.
		* The right zone: the coconut will bounce to the extrem right.
