Try this:
sync on : sync rate 60 :
color backdrop rgb(0,0,128) : hide mouse
set text font "arial" : set text size 12 : set text transparent
autocam off
position camera 0,30,30,30
point camera 0,0,0,0
make object box 1,10,10,10
set object cull 1,0
a=8:b=9:c=10:d=11
for l=1 to 20
lock vertexdata for limb 1,0
set vertexdata position a,get vertexdata position x(a),get vertexdata position y(a)+1,get vertexdata position z(a)
set vertexdata position b,get vertexdata position x(b),get vertexdata position y(b)+1,get vertexdata position z(b)
set vertexdata position c,get vertexdata position x(c),get vertexdata position y(c)+1,get vertexdata position z(c)
set vertexdata position d,get vertexdata position x(d),get vertexdata position y(d)+1,get vertexdata position z(d)
unlock vertexdata
sleep 50
sync
next l
repeat
center text screen width()/2,screen height()/2-30,"I found the lid!"
sync
until mouseclick()<>0
end
Whatever...
