au3Irr2 Function Reference
_IrrAddNodeShadowAdds shadows to a node that are cast across other nodes in the scene.
#Include <au3Irrlicht2.au3>
_IrrAddNodeShadow($h_Node, $h_mesh = 0)
Parameters
| $h_Node | Handle of a node in the scene |
| $h_mesh | [optional] Handle of mesh casting the shadow (0 uses mesh of h_Node, see remarks) |
Return Value
Success: TrueFailure: False
Remarks
_IrrAddShadows will only work when shadowing has been activated with _IrrStart or _IrrStartAdvanced.You should analyse the performance of your scene carefully when using this function as it can have a significant effect on your frame rate.
You can supply a different mesh to the one used to display the node, this shadow mesh could be a much lower resoloution than that used for your model thereby improving performance.
_IrrAddNodeShadow does NOT work with buildin nodes types _IrrAddTestSceneNode, _IrrAddCubeSceneNode, and _IrrAddSphereSceneNode. If you need a cube or a sphere casting shadows, create a node from a loaded cube or sphere mesh as workaround.
