SetVertexPosition not registering

[Joe]

I am working on an imported fbx model and i want to adjust the physical appearance in real time, but the functions for setting vertex positions do not have any visible effect on the model. Is this code wrong or is it not implemented in lua or what? thanks for your interest

 

 

local v = vertex

self.hits = self.hits + 1

local sfc = self.entity:GetSurface(0)

local vp = sfc:GetVertexPosition(v)

local vn = vp:Normalize() * 0.5

local offset = vp + (Vec3(0) - vn)

sfc:SetVertexPosition(v,offset)

self.entity:UpdateAABB(self.entity.LocalAABB)

self.entity:UpdateAABB(self.entity.GlobalAABB)

self.entity:UpdateAABB(self.entity.RecursiveAABB)

System:Print(vp)

System:Print(offset)

The example code located here works just fine and as a test I tried it on a model and it worked as well. You are not updating the surface AABB, normals, binormals, and tangents.

sfc:Update()

 

Other than that I would just suggest you 'System:Print' each value to make sure the values are what you expect.

 

also on a side note, the forum allows you to put code into code tags which makes reading code easier on old guys like myself. Look for the '<>' icon on the toolbar.

 

--Edit you need to update several things - which is covered by Surface:Update() instead of just surface:UpdateAABB()

thanks macklebee i thought it was something like that
