Crocodile - numberZero/CrocoLogic GitHub Wiki

Class name is self-describing =)

On each logical step, methods should be called for all crocodiles on the map in order:

1. update()
2. think()
3. go()

Each method must be called for all crocodiles before next method is called.

And each animation step only step() should be called. It may never be called if animation is not needed.

Properties

State-describing properties

• integer id
  Crocodile ID. Currently almost not meaningful.
• Cell field
  Field the crocodile is in.
• Cell target
  Field the crocodile moves to.
• integer sleep
  Count of logic steps the crocodile will sleep.
• integer dir
  Current direction.
• boolean omnicroc
  Describes can the crocodile change its direction.
• integer ate
  Count of Meats ate.

Visual-only properties:

• HTMLImageElement img
  Crocodile image.
• string[] images
  Crocodile images paths; depends on initial value of the omnicroc property.
• float sleepiness
  Same as sleep, but changes every animation step
• float x, y
  Image coordinates (changes every animation step)
• float vx, vy
  Image speed

Related properties:

• Crocodile field.content
  Refers to the crocodile.
• Crocodile img.object Refers to the crocodile.

Methods

constructor

new Crocodile(Cell cell, integer dir)

Creates new crocodile on given cell with given direction, if possible, and throws exception otherwise.

If dir is equal to dirAuto, omnicroc is created with initial direction set to 0.

die

void this.die(void)

Deletes the crocodile. Should not be used.

See _Die().

updateImageParams

void this.updateImageParams(void)

Updates image position and opaticy according to the crocodile properties.

updateImage

void this.updateImage(void)

Updates image according to the crocodile properties.

step

void this.step(void)

Does one animation step.

update

void this.update(void)

Updates crocodile properties according to its moving. Updates references to and from map.

think

void this.think(void)

Searches where the crocodile wants to go. Uses checkForMeat().

go

void this.go(void)

Starts walking to choosed by think() cell, if possible.

walk

void this.walk(void)

Starts walking animation in current direction.

checkForMeat

integer this.checkForMeat(integer dir)

Check is there reachable meat in given direction. Returns distance to it, or Number.POSITIVE_INFINITY otherwise.
