◆ onAfterDeserialized()

void ne::SpotlightNode::onAfterDeserialized ( )
overrideprotectedvirtual

Called after the object was successfully deserialized. Used to execute post-deserialization logic.

Warning
If overriding you must call the parent's version of this function first (before executing your login) to execute parent's logic.

Reimplemented from ne::SpatialNode.

◆ onDespawning()

void ne::SpotlightNode::onDespawning ( )
overrideprotectedvirtual

Called before this node is despawned from the world to execute custom despawn logic.

Remarks
This node will be marked as despawned after this function is called.
This function is called after all child nodes were despawned.
Warning
If overriding you must call the parent's version of this function first (before executing your login) to execute parent's logic.

Reimplemented from ne::Node.

◆ onFinishedUpdatingShaderData()

Parameters
iNewIndexIntoArrayNew index to use.

◆ onSpawning()

void ne::SpotlightNode::onSpawning ( )

Remarks
This node will be marked as spawned before this function is called.
This function is called before any of the child nodes are spawned. If you need to do some logic after child nodes are spawned use onChildNodesSpawned.
Warning
If overriding you must call the parent's version of this function first (before executing your login) to execute parent's logic.

Reimplemented from ne::SpatialNode.

◆ onStartedUpdatingShaderData()

void * ne::SpotlightNode::onStartedUpdatingShaderData ( )
private

Callback that will be called by the renderer when it's ready to copy new (updated) mtxShaderData to the GPU resource.

Returns
Pointer to the shader data at mtxShaderData.

◆ onStartedUpdatingShadowPassData()

void * ne::SpotlightNode::onStartedUpdatingShadowPassData ( )

Returns
Pointer to the viewProjectionMatrix at mtxShaderData.

◆ onWorldLocationRotationScaleChanged()

void ne::SpotlightNode::onWorldLocationRotationScaleChanged ( )
overrideprotectedvirtual
