Method Detail

draw

public void draw(java.awt.Graphics2D g2d)

Vykreslenie objektu. Kazdy objekt dostane svoju kopiu g2d, takze 1) g2d obsahuje defaultne stavove informacie 2) stavove informacie v g2d nie je potrebne vratit do povodneho stavu. Metoda posunie stred suradnicovej sustavy g2d podla pozicie objektu. Metoda natoci suradnicovu sustavu g2d podla natocenia objektu.

Overrides:

draw in class AbstractDrawableMovableObject

getRotation

public double getRotation()

Vrati natocenie v radianoch

Returns:

natocenie v radianoch

setRotation

public void setRotation(double angle)

Nastavy natocenie v radianoch

Parameters:

angle -

addRotation

public void addRotation(double deltaAngle)

Zmeni natocenie o deltaAngle (v radianoch)

Parameters:

deltaAngle -

move

public void move(double length)

Zmeni poziciu o length v smere danom podla uhla natocenia

Parameters:

length - vzdialenost o ktoru sa objekt posunie v smere natocenia

externalToInternalCoordinates

public Position externalToInternalCoordinates(Position externalPosition)

Prepocita poziciu danu vo vonkajsej suradnicovej sustave objektu na poziciu v suradnicovej sustave objektu (v jeho vnutornej suradnicovej sustave). Do vypoctu su zahrnute len transformacie objektu (posuv, rotacia, zmensenie) nad ktorym sa metoda vola. Nie su zahrnute transformacie skupiny do ktorej objekt patri. Transformacie skupiny do ktorej objekt patri su zahrnute v metode AbstractDrawableObject.globalToInternalCoordinates(Position).

Overrides:

externalToInternalCoordinates in class AbstractDrawableMovableObject

Parameters:

externalPosition - pozicia vo vonkajsej suradnicovej sustave

Returns:

pozicia vo vnutornej suradnicovej sustave objektu

internalToExternalCoordinates

public Position internalToExternalCoordinates(Position internalPosition)

Prepocita poziciu danu vo vnutornej suradnicovej sustave objektu na poziciu vo vonkajsej suradnicovej sustave objektu. Do vypoctu su zahrnute len transformacie objektu (posuv, rotacia, zmensenie) nad ktorym sa metoda vola. Nie su zahrnute transformacie skupiny do ktorej objekt patri. Transformacie skupiny do ktorej objekt patri su zahrnute v metode AbstractDrawableObject.internalToGlobalCoordinates(Position).

Overrides:

internalToExternalCoordinates in class AbstractDrawableMovableObject

Parameters:

internalPosition - pozicia vo vnutornej suradnicovej sustave objektu

Returns:

pozicia vo vonkajsej suradnicovej sustave

toString

public java.lang.String toString()

Overrides:

toString in class AbstractDrawableMovableObject
