render

public void render(Graphics2D g)

Description copied from interface: IRenderable

Renders the visual contents of this instance onto the provided graphics context.

If an Entity implements this interface, this method will be called right after the entity was rendered from the environment. Allowing for a custom rendering mechanism.

This interface can be implemented in general by anything that should be rendered to the game's screen.

Specified by:

render in interface IRenderable

Parameters:

g - The current graphics object onto which this instance will render its visual contents.

setAllowDiagonalMovement

public void setAllowDiagonalMovement(boolean allowDiagonalMovement)

setAllowCuttingCorners

public void setAllowCuttingCorners(boolean allowCuttingCorners)

updateWalkable

public void updateWalkable(Rectangle2D rectangle)

Updates the walkable attribute of nodes intersected by the specified rectangle.

Parameters:

rectangle - The rectangle within which the nodes should be updated.

assignPenalty

protected void assignPenalty(AStarNode node)
