Class: R3d.ConvexMeshShape
Description
Creates a new collision convex mesh shape (fixture). <syntaxhighlight lang="lua"> r3d.ConvexMeshShape.new(vertices,indices,faces) </source>
Parameters
vertices: (table) the vertex array table
indices: (table) the index array table
faces: (table) the face array table
Example
A cylinder shape <syntaxhighlight lang="lua"> --For collision, ensure closed/CCW shape local steps=8 local ca,fa={},{} local nc,nf=1,1 for i=3,steps*4-1,4 do ca[nc]=i+1 nc+=1 end fa[nf]=steps nf+=1 for i=3,steps*4-1,4 do ca[nc]=i+1 nc+=1 ca[nc]=i+2 nc+=1 ca[nc]=i+6 nc+=1 ca[nc]=i+5 nc+=1 fa[nf]=4 nf+=1 end ca[nc-2]=5 ca[nc-1]=4 for i=steps*4-1,3,-4 do ca[nc]=i+2 nc+=1 end fa[nf]=steps nf+=1
