setAll(key, value, checkAlive, checkVisible, operation, force)
-
This function allows you to quickly set the same property across all children of this Group to a new value. This call doesn't descend down children, so if you have a Group inside of this Group, the property will be set on the Group but not its children. If you need that ability please see
Group.setAllChildren
.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.- Inherited From:

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.- Inherited From:

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.

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 yourState.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.- Inherited From:

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.

Parameters:
Name Type Description child1
* The first child to swap.
child2
* The second child to swap.
