Method Detail

setScreenSize

public void setScreenSize(int width,
                          int height)

setMapScreenCenter

public void setMapScreenCenter(float pivotY)

Set pivot height relative to screen center. E.g. 0.5 is usually preferred for navigation, moving the center to 25% of the screen height. Range is [-1, 1].

moveMap

public void moveMap(float mx,
                    float my)

Moves this Viewport by the given amount of pixels.

Parameters:

mx - the amount of pixels to move the map horizontally.

my - the amount of pixels to move the map vertically.

scaleMap

public boolean scaleMap(float scale,
                        float pivotX,
                        float pivotY)

Scale map by scale width center at pivot in pixel relative to screen center. Map scale is clamp to MIN_SCALE and MAX_SCALE.

Returns:

true if scale was changed

rotateMap

public void rotateMap(double radians,
                      float pivotX,
                      float pivotY)

Rotate map by radians around pivot. Pivot is in pixel relative to screen center.

setRotation

public void setRotation(double degree)

tiltMap

public boolean tiltMap(float move)

setTilt

public boolean setTilt(float tilt)

setMapPosition

public void setMapPosition(MapPosition mapPosition)

getSyncViewport

public final Viewport getSyncViewport()

synchronize on this object when doing multiple calls on it

getSyncViewport

public boolean getSyncViewport(Viewport v)

getSyncMapPosition

public boolean getSyncMapPosition(MapPosition mapPosition)
