Class Drawing

java.lang.Object
  sema.Drawing

public class Drawing

extends java.lang.Object

Graphics and parameters. This class is in charge of all the drawing within the simulation. An element of the world must use this class to draw itself, because Drawing is the only class in Sema which knows the graphics context. The main advantage is that the elements don't have to convert dimensions between simulated units and pixels.

Field Detail

boxFactor

public final float boxFactor

Default boxfactor to use for the simulation. The box factor allows to have a more accurate simulation by increasing the number of boxes on the map, with the same dimensions of the map (so, xBoxes and yBoxes and boxLength parameters of the map are linked to this one).

pixelsByUnitZoom1x

public final float pixelsByUnitZoom1x

Pixels by simulated unit, when zoom=1.

pixelsByBoxZoom1x

public final float pixelsByBoxZoom1x

Pixels by square box side, when zoom=1.

centerX

public final float centerX

X-coordinate to center the map by default.

centerY

public final float centerY

Y-coordinate to center the map by default.

minZoom

public final float minZoom

Min value of the zoom slider in the interface.

maxZoom

public final float maxZoom

Max value of the zoom slider in the interface.

minTfactor

public final float minTfactor

Max value of the time factor slider in the interface.

maxTfactor

public final float maxTfactor

Max value of the time factor slider in the interface.

tFactor

public final float tFactor

Default temporal factor.

virtualDelay

public final float virtualDelay

Default virtual delay (in ms) between to displays of the world in the graphical interface.

realDelay

public final int realDelay

Default virtual delay (in ms) between to displays of the world in the graphical interface. As the system time returned by System.currentTimeMillis() is an integer (a long), it doesn't need to be a float.
