Class: BodyDebug

Phaser.Physics.P2. BodyDebug

Physics Body Debug Constructor

new BodyDebug(game, body, settings)

Draws a P2 Body to a Graphics instance for visual debugging. Needless to say, for every body you enable debug drawing on, you are adding processor and graphical overhead. So use sparingly and rarely (if ever) in production code.

Parameters:
Name Type Description
game Phaser.Game

Game reference to the currently running game.
body Phaser.Physics.P2.Body

The P2 Body to display debug data for.
settings object

operation number <optional>
 0

Controls how the value is assigned. A value of 0 replaces the value with the new one. A value of 1 adds it, 2 subtracts it, 3 multiplies it and 4 divides it.
force boolean <optional>
 false

If force is true then the property will be set on the child regardless if it already exists or not. If false and the property doesn't exist, nothing will be set.

setAllChildren(key, value, checkAlive, checkVisible, operation, force)

This function allows you to quickly set the same property across all children of this Group, and any child Groups, to a new value.

If this Group contains other Groups then the same property is set across their children as well, iterating down until it reaches the bottom. Unlike with Group.setAll the property is NOT set on child Groups itself.

The operation parameter controls how the new value is assigned to the property, from simple replacement to addition and multiplication.

Parameters:
Name Type Argument Default Description
key string

The property, as a string, to be set. For example: 'body.velocity.x'
value *

The value that will be set.
checkAlive boolean <optional>
 false

If set then only children with alive=true will be updated. This includes any Groups that are children.
checkVisible boolean <optional>
 false

If set then only children with visible=true will be updated. This includes any Groups that are children.
operation number <optional>
 0

Controls how the value is assigned. A value of 0 replaces the value with the new one. A value of 1 adds it, 2 subtracts it, 3 multiplies it and 4 divides it.
force boolean <optional>
 false

If force is true then the property will be set on the child regardless if it already exists or not. If false and the property doesn't exist, nothing will be set.

Source:

setProperty(child, key, value, operation, force) → {boolean}

Sets a property to the given value on the child. The operation parameter controls how the value is set. Operation 0 means set the existing value to the given value, or if force is false create a new property with the given value. 1 will add the given value to the value already present. 2 will subtract the given value from the value already present. 3 will multiply the value already present by the given value. 4 will divide the value already present by the given value.

Parameters:
Name Type Argument Default Description
child *

The child to set the property value on.
key array

An array of strings that make up the property that will be set.
value *

The value that will be set.
operation number <optional>
 0

Controls how the value is assigned. A value of 0 replaces the value with the new one. A value of 1 adds it, 2 subtracts it, 3 multiplies it and 4 divides it.
force boolean <optional>
 false

If force is true then the property will be set on the child regardless if it already exists or not. If false and the property doesn't exist, nothing will be set.

sort(index, order)

Call this function to sort the group according to a particular value and order. For example to depth sort Sprites for Zelda-style game you might call group.sort('y', Phaser.Group.SORT_ASCENDING) at the bottom of your State.update().

Parameters:
Name Type Argument Default Description
index string <optional>
 'z'

The string name of the property you want to sort on. Defaults to the objects z-depth value.
order number <optional>
 Phaser.Group.SORT_ASCENDING

The Group constant that defines the sort order. Possible values are Phaser.Group.SORT_ASCENDING and Phaser.Group.SORT_DESCENDING.

subAll(property, amount, checkAlive, checkVisible)

Subtracts the amount from the given property on all children in this Group. Group.subAll('x', 10) will minus 10 from the child.x value.

Parameters:
Name Type Description
property string

The property to decrement, for example 'body.velocity.x' or 'angle'.
amount number

The amount to subtract from the property. If child.x = 50 then subAll('x', 40) would make child.x = 10.
checkAlive boolean

If true the property will only be changed if the child is alive.
checkVisible boolean

If true the property will only be changed if the child is visible.
