Player.X > VerticalFan.X - (VerticalFan.Width / 2)
This checks if the player's X position is greater than the left edge of the fan.
VerticalFan.X: The X position of the center of the fan.
VerticalFan.Width / 2: Half of the fan's width, which gives you the distance from the center to the left edge.
So, the expression VerticalFan.X - (VerticalFan.Width / 2) calculates the left edge of the fan. If the player's X position is greater than this value, it means the player is to the right of the left edge.
Player.X < VerticalFan.X + (VerticalFan.Width / 2)
This checks if the player's X position is less than the right edge of the fan.
VerticalFan.X + (VerticalFan.Width / 2) calculates the right edge of the fan (center of the fan plus half of its width).
If the player's X position is less than this value, it means the player is to the left of the right edge.
Let’s say the fan's center X position is 500 and its width is 100.
The left edge would be at 500 - (100 / 2) = 450.
The right edge would be at 500 + (100 / 2) = 550.
If the player's X position is between 450 and 550, the conditions will be true, meaning the player is within the fan's area.
