Field Detail

size

private java.awt.Dimension size
size of the window in pixels

ship_images

private java.awt.image.BufferedImage[] ship_images
image series for the boat

sail_images

private java.awt.image.BufferedImage[] sail_images
image series for the sail

wind_images

private java.awt.image.BufferedImage[] wind_images
image series for the wind sock

direction_images

private java.awt.image.BufferedImage[] direction_images
image series for the guiding arrow

seatile_image

private java.awt.image.BufferedImage seatile_image
image of sea waves

red_image

private java.awt.image.BufferedImage red_image
image of red buoy

green_image

private java.awt.image.BufferedImage green_image
image of green buoy

pix_per_m

private float pix_per_m
Tells how many pixels on the screen represent one metre.

If e.g. the boat is 5m long and it's length in the image is 64 pixels, we get a multiplier of about 64 px / 5 m = 12.8 px/m.

look_at

private Vector2 look_at
The point in the world where we direct our view to.

This is the point in the world that we see in the center of the screen. The idea is to stay centered on one's own boat.
