Class PlayField

java.lang.Object
  |
  +--PlayField

public class PlayField
extends Object

Field Summary
`Food[][]`	`playfield` two-dimensional array of food; allows the microbes to have a fast access to the playfield
`int`	`playfield_height` width and height of the playfield in units
`int`	`playfield_width` width and height of the playfield in units
`static int`	`TYPE_DEATH` additional drawmode: death
`static int`	`TYPE_NEWLIFE` additional drawmode: new life
`static int`	`TYPE_RANDOMFOOD` additional drawmode: random

Constructor Summary
`PlayField(int width, int height, int pixelsize)` creates the playfield with the parameters

Method Summary
`void`	`clear_all()` fills the whole playfield with the food Food.TYPE_NOTHING
`void`	`draw_all()` draws the whole playfield (without microbes!)
`void`	`fill_all(int color)` fills the whole playfield with the food "color" and creates the playfield borders the playfield borders are hardcoded into the microbes brain to be unpassable
`void`	`fill_random()` lets "rain" food in random order onto the playfield
`Microbe`	`get_selectedmic()` returns the selected microbe
`int`	`getfoodtype(int x, int y)` returns the food type at the position (x,y) in the playfield
`void`	`manualdraw(int x, int y, int type, int size)` draws the food "type" with the brush size "size" onto the position (x,y)
`Microbe`	`new_microbe(int x, int y, int start_energy, int start_energyloss)` creates a new microbe
`void`	`refresh()` calculates one step of every microbe and draws the changes
`void`	`remove_microbe(int x, int y)` removes the microbe at the position (x,y) on the playfield
`void`	`set_graphics(Graphics g)` sets graphics context for all further graphic operations
`void`	`setenergyloss(int new_energyloss)` sets the energyloss per stepp for every microbe

Constructor Detail

PlayField

public PlayField(int width,
                 int height,
                 int pixelsize)

creates the playfield with the parameters

Parameters:: width - width of playfield in playfield-grid-points; height - height of playfield in playfield-grid-points; pixelsize - size of a pixel in the playfield (quadratic, unit: pixels)

Method Detail

set_graphics

public void set_graphics(Graphics g)

sets graphics context for all further graphic operations

Parameters:: g - graphics context

fill_all

public void fill_all(int color)

fills the whole playfield with the food "color" and creates the playfield borders
the playfield borders are hardcoded into the microbes brain to be unpassable

Parameters:: color - color (food-type) to fill the playfield with

clear_all

public void clear_all()

fills the whole playfield with the food Food.TYPE_NOTHING

fill_random

public void fill_random()

lets "rain" food in random order onto the playfield

manualdraw

public void manualdraw(int x,
                       int y,
                       int type,
                       int size)

draws the food "type" with the brush size "size" onto the position (x,y)

Parameters:: x - x position; y - y position; type - food type; size - size of the drawing brush

setenergyloss

public void setenergyloss(int new_energyloss)

sets the energyloss per stepp for every microbe

Parameters:: new_ernergyloss - new energyloss per step value

getfoodtype

public int getfoodtype(int x,
                       int y)

returns the food type at the position (x,y) in the playfield

Parameters:: x - x position; y - y position
Returns:: food type

draw_all

public void draw_all()

draws the whole playfield (without microbes!)

refresh

public void refresh()

calculates one step of every microbe and draws the changes

new_microbe

public Microbe new_microbe(int x,
                           int y,
                           int start_energy,
                           int start_energyloss)

creates a new microbe

Parameters:: x - x position; y - y position; start_energy - start energy for thge new microbe; start_energyloss - energy loss per step
