		int	vertical_speed
	)

explicit

Member Function Documentation

◆ col()

int Fish::col ( ) const

Returns: column (x-coordinate) of the top left character

Definition at line 15 of file fish.cpp.

◆ draw()

void Fish::draw ( Screen * screen ) const

Render to the given Screen. Draws over whatever is already there with no concept of transparency.

Because Fish::col and Fish::row return unwrapped coordinates, Fish::draw wraps them to the dimensions of the Screen.

Definition at line 38 of file fish.cpp.

◆ height()

int Fish::height ( ) const

Returns: height of the grid of characters

Definition at line 21 of file fish.cpp.

◆ row()

int Fish::row ( ) const

Returns: row (y-coordinate) of the top left character

Definition at line 17 of file fish.cpp.

◆ tick()

void Fish::tick ( )

Update col using horizontal_speed. Update row using vertical_speed.

Definition at line 23 of file fish.cpp.

◆ width()

int Fish::width ( ) const

Returns: width of the grid of characters

Definition at line 19 of file fish.cpp.
