| Node Class |
A basic scene node with transformations.
You can attach renderable entities to it, or child nodes that will inherit its transformations.

public class Node
The Node type exposes the following members.
ConstructorsProperties| Name | Description | |
|---|---|---|
 | CanHoldEntities |
Get if this node can hold renderable entities (if not, it means this node is just for child nodes, and not for entities.
|
| Empty |
Return true if this node is empty.
|
| HaveEntities |
Get if this node have any entities in it.
|
| LastDrawFrame |
Last frame this node was drawn.
|
| LocalTransformations |
Return local transformations matrix (note: will recalculate if needed).
|
| Parent |
Parent node.
|
| Position |
Get / Set node local position.
|
| PositionX |
Alias to access position X directly.
|
| PositionY |
Alias to access position Y directly.
|
| PositionZ |
Alias to access position Z directly.
|
| Rotation |
Get / Set node local rotation.
|
| RotationOrder |
Get / Set the order in which we apply local rotation in this node.
|
| RotationType |
Get / Set the rotation type (euler / quaternion).
|
| RotationX |
Alias to access rotation X directly.
|
| RotationY |
Alias to access rotation Y directly.
|
| RotationZ |
Alias to access rotation Z directly.
|
| Scale |
Get / Set node local scale.
|
| ScaleX |
Alias to access scale X directly.
|
| ScaleY |
Alias to access scale Y directly.
|
| ScaleZ |
Alias to access scale Z directly.
|
| TransformationsOrder |
Get / Set the order in which we apply local transformations in this node.
|
| TransformVersion |
Transformation version is a special identifier that changes whenever the world transformations
of this node changes. Its not necessarily a sequence, but if you check this number for changes every
frame its a good indication of transformation change.
|
| UseExternalTransformations |
If true, it means transformations are coming from external source (like a physical body).
If you set it true, this node will no longer calculate transformations on its own, and you'll need to use
'SetWorldTransformsMatrix()' to update the world matrix.
|
| Visible |
Is this node currently visible?
|
| WasDrawnThisFrame |
Get if this node was drawn in current frame.
|
| WorldPosition |
Get position in world space.
|
| WorldRotation |
Get Rotastion in world space.
|
| WorldScale |
Get Scale in world space.
|
| WorldTransformations |
Return world transformations matrix (note: will recalculate if needed).
|
Methods| Name | Description | |
|---|---|---|
 | AddChildNode |
Add a child node to this node.
|
| AddEntity |
Add an entity to this node.
|
| BuildTransformationsMatrix |
Build matrix from node transformations.
|
| Clone |
Clone this scene node.
|
| Draw |
Draw the node and its children.
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| FindChildNode |
Find and return first child node by identifier.
|
| ForceFullUpdate |
Force this node to update transformation and recalculate bounding box and sphere.
|
| GetBoundingBox |
Get up-to-date bounding box of this node and all its child nodes, and recalculate it if needed.
|
| GetBoundingSphere |
Get up-to-date bounding sphere of this node and all its child nodes, and recalculate it if needed.
|
| GetDebugString |
Get a debug string representation of this scene node and its children.
|
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| OnChildWorldMatrixChange |
Called every time one of the child nodes recalculate world transformations.
|
| RemoveChildNode |
Remove a child node from this node.
|
| RemoveEntity |
Remove an entity from this node.
|
| RemoveFromParent |
Remove this node from its parent.
|
| ResetTransformations |
Reset all local transformations.
|
| SetWorldTransforms |
Set world transformations from external source.
To prevent the node from overriding these changes, set 'UseExternalTransformations' to true.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Transform |
Transform a given transformations and return the result matrix.
|
| Translate |
Move position by vector.
|
| UpdateBoundingBox |
Recalculate bounding box of this node and all its child nodes.
|
| UpdateBoundingSphere |
Calculate bounding sphere and return results.
This also set internal caching.
|
| UpdateTransformations |
Update transformations for this node and its children, if needed.
|
Fields| Name | Description | |
|---|---|---|
  | BoundingShapesTtl |
For how many rendering frames bounding box / bounding sphere hold in cache.
|
| DisableCulling |
Is culling enabled for this scene node.
Note: while this is not used for based node types, its a generic property for inheriting nodes.
|
| Identifier |
Optional identifier we can give to nodes.
|
| UserData |
Optional user data we can attach to nodes.
