AutoMidHandle for Static and Animated Mesh.

This function will center a static mesh assuming it has a depth, height and width of > 0

``````Function MESHmidhandle( mesh )

Mw# = meshwidth( mesh )
Mh# = meshheight( mesh )
Md# = meshdepth( mesh )
fitmesh mesh, -.5*mw, -.5*mh, -.5*md, mw,mh,md

End Function``````

For animated meshes you cant use meshwidth on it but could try the code below.

It loads an animmesh and scales it using blitz units.

tharefore if you make it 4,4,4 you know the center is x+2,y+2,z+2

create a pivot at this point and parent the mesh to it and voila! a centrally referenced mesh

``````Function loadscaledanimmesh(filename\$, sx#,sy#,sz#) ;Size in blitz units not percent!!

;By Dan @ D-Grafix

;create scaler and mesure static mesh
mesh_SX#        =MeshWidth(scaler)
mesh_SY#    =MeshHeight(scaler)
mesh_SZ#        =MeshDepth(scaler)

;and bin it
FreeEntity scaler

;do some maths
Xscale#     = ((100/mesh_SX)   * sx) / 100.0
Yscale#     = ((100/mesh_SY)  * sy) / 100.0
Zscale#     = ((100/mesh_SZ)  * sz) / 100.0

;scale it
ScaleEntity mesh,Xscale#,Yscale#,Zscale#

;return it
Return mesh

End Function``````
