Example

_IrrStart()
local $mesh = _IrrGetMesh( "./media/cube.x" )
local $tVertex; variable for the vertex array struct
; copy the vertex information into the array
local $vertex_count = _IrrGetMeshVertices( $mesh, 0, $tVertex)
local $i
for $i = 0 to $vertex_count - 1 ; itterate through all of the vertices
; shrink vertex X location by half its size, then change vertex colour value
__SetVertStruct($tVertex, $i, $VERT_X, __GetVertStruct($tVertex, $i, $VERT_X) * 0.5 )
__SetVertStruct($tVertex, $i, $VERT_VCOLOR, _IrrMakeARGB(0, Random(0,255), Random(0,255), Random(0,255) ) )
next ; $i
; copy the altered vertex infomation back to the mesh
_IrrSetMeshVertices( $mesh, 0, $tVertex )
; add mesh and camera to the scene:
local $nodeCube = _IrrAddMeshToScene( $mesh )
