public class JDisplDaemon

extends JDaemon

Displacement daemon element in the world

A displacement daemon is a special daemon that affects only atoms when they collide with it.

It is displayed as an arrow. It changes the velocity of the atom (regardless of its previous velocity) to make it travel over the arrow and then stop at the end of the arrow. The speed of the atom while it is traveling over the displacement daemon depends on the speed mode of the daemon. By default, the atom will always travel through the daemon in 1 second, but the daemon can be set as make the atoms travel with a constant speed.

createDisplDaemon

public static JDisplDaemon createDisplDaemon(float x,
                                             float y,
                                             float w,

                                             float displY)

Creates a new displacement daemon.

It is created in the given position (x,y) and with a displacement of (displX,displY). The w and h parameters are only used to give a width and height on the center of the daemon when the displacement is 0 and it needs to be dragged.

Parameters:

x - daemon's x coordinate

y - daemon's y coordinate

w - daemon's graphical width (minimum 1)

h - daemon's graphical height (minimum 1)

displX - daemon's displacement in x

displY - daemon's displacement in y

setSpeedMode

public void setSpeedMode(int v)

Sets the speed mode of the daemon that will determine the actual speed of the atoms that collide with it.

Parameters:

v - represents the speed the atom will have after colliding with the daemon:

• SPEED_MODE_TIMECONSTANT atom will always travel the daemon in 1 sec
• SPEED_MODE_CONSTANT atom will travel the daemon at a constant speed regardless of the lenght of the arrow (see setSpeedModeConstant)
• SPEED_MODE_PROPORTIONAL the atom's speed is calculated taking x and y separately, so the time an atom will take to travel from one point to another will be always the same regardless of the path

Parameters:

v - constant speed the atom will have after colliding with the daemon

See Also:

setSpeedMode(int)

getSpeedModeConstant
