au3Irr2 Function Reference
_IrrSetMeshVerticesThis sets the value of the list of vertices in a mesh copying them from the supplied vertex array struct.
#Include <au3Irrlicht2.au3>
_IrrSetMeshVertices($h_Mesh, $i_FrameNumber, ByRef $tVertex, $i_MeshBuffer = 0)
Parameters
| $h_Mesh | Handle to a mesh object |
| $i_FrameNumber | Frame number of the mesh to write vertices to (should be 0 for static meshes). |
| $i_MeshBuffer | [optional] Mesh buffer to access. |
Return Value
Success: None.Failure: False and @error = 1
Remarks
Each vertex represents a point in the mesh that is the corner of one of the group of triangles that is used to construct the mesh.If the mesh is animated frame number indicates the number of the frame to recover mesh data for if it is not animated this value should be set to 0.
If the mesh contains a number of mesh buffers you can specific which mesh buffer you want to access, if you omit this parameter mesh buffer 0 will be used.
