SceneNodeList

Kind: class

Represents the children of a scenenode. Typically accessed via the SceneNode.children property.

This is not an Array, so you must use .at(i) instead of [i] to access children by index. It has a number of Array-like methods such as forEach for convenience, however. For best performance, iterate the list using these methods rather than repeatedly calling at().

Items in this list are ordered from lowest z order to highest.

Example

let node = ...;
console.log("Node has " + node.children.length + " children");
console.log("First child: " + node.children.at(0));  // do not use `[0]` - it will not work!
node.children.forEach(function (childNode, i) {
    ...
});

See: SceneNode.children

length

▸ length: number

Number of children in the list.

Kind: instance property of SceneNodeList Read only: true

forEach()

▸ forEach(callback, thisArg)

Iterate all children in the list.

Kind: instance method of SceneNodeList

forEachRight()

▸ forEachRight(callback, thisArg)

Iterate all children in the list, in reverse order (highest z order to lowest).

Kind: instance method of SceneNodeList

filter()

▸ filter(callback, thisArg): Array.<SceneNode>

Iterates all children and returns an array of just the children that passed the filter function's test.

Kind: instance method of SceneNodeList

map()

▸ map(callback, thisArg): Array.<*>

Iterates all children and returns an array of the map function's result value for each child node.

Kind: instance method of SceneNodeList

some()

▸ some(callback, thisArg): boolean

Iterates children until the test returns true for at least one child. Returns true if the test function returned true for at least one child.

Kind: instance method of SceneNodeList

at()

▸ at(index): SceneNode

Returns the child node at the specified index in the list, or null if index is out of bounds.

Note: calling at() repeatedly (e.g. in a for loop) is not as fast as using SceneNodeList's iteration methods such as forEach(), some(), or map().
