Constructor Detail

ComputerBoat

public ComputerBoat(BoatType boat,
                    Lane lane,
                    java.lang.String name,
                    int pickSpeedValue)

Creates a computer boat with values from boat, in Lane lane, an identifying name and with a random speed.

Parameters:

boat - The BoatType to get values from.

lane - The lane the boat is racing in.

name - The name of the boat.

pickSpeedValue - The speed of the boat is chosen based on this value.

Method Detail

update

public void update(float deltaTime)

Update the position of the boat in respect to the time passed since the last frame.

Overrides:

update in class Boat

Parameters:

deltaTime - The time passed since the last frame.

render

public void render(com.badlogic.gdx.graphics.g2d.SpriteBatch batch)

Renders the boat if it is onscreen, else will render the off-screen markers at their current x value.

Also performs Boat's render after rendering the markers.

Overrides:

render in class Boat

Parameters:

batch - The SpriteBatch that the renders will be added to.

updateYPosition

public void updateYPosition(float playerY,
                            float playerDistance)

Update the vertical position of the boat according to its distance travelled versus the distance travelled by the player.

Parameters:

playerY - The y position of the player on the screen.

playerDistance - The distance travelled by the player.

waitForRandomStamina

private float waitForRandomStamina()

Wait for a random stamina value before using stamina again.

Returns:

A float of the value to wait for before using stamina.

checkCollidables

private Collidable checkCollidables()

Check for obstacles in the area, specified by moveArea, to move away from.

Returns:

The closest Obstacle in the area or null if no obstacles are in the area.

moveFromObject

private int moveFromObject(Collidable closest)

Move in the direction away from an object.

Parameters:

closest - The Obstacle to move away from.

Returns:

The direction to move in:

• -1 if the boat should move to the left.
• 1 if the boat should move to the right.
• 0 if the boat should move neither way.

pickSpeed

private float pickSpeed(int pos)
