formatting lists in jit.gl.lua
Dear all,
I am using these Lua scripts to update the motion of objects in a gl world, but I can't seem to format the output lists so that I don't need to use a zl.join when I get back to Max. Any help is appreciated!

--begin LUA script example-orbit.lua
this.outlets=2
local S = 1.
local Sc = 1.
function speed(v)
S = v
end
function size(v)
Sc = v
end
function list(...)
local values = {...}
local message={}
values[5] = Sc*values[10]*(math.sin(2*math.pi*values[9]))
values[6] = Sc*values[11]*(math.cos(2*math.pi*values[9]))
values[7] = 0.
values[9] = values[9]+S*((values[8]-.5)/100.)
message={"setcell", INT, "val"}
outlet(0,message)
outlet(1,values)
end
function int(v)
INT=v
end
--end LUA example-orbit.lua
--begin LUA example3.lua
this.outlets=2
function list(...)
local values = {...}
local message={}
values[5] = values[5]*2.-1
values[6] = values[6]*2.-1
values[7] = values[7]*2.-1
values[11] = values[10]
message={"setcell", INT, "val"}
outlet(1,values)
outlet(0,message)
end
function int(v)
INT=v
end
--end LUA example3.lua
Here is the patch in which I'm using these scripts:
Aha -- solved it. Here's how to join tables (lists) in Lua where RIGHT and LEFT are two tables to be joined:
for k,v in ipairs(RIGHT) do LEFT[#LEFT+1]=v end
J
You got it. You can also do:
for i=1, #RIGHT do
LEFT[#LEFT+1] = RIGHT[i]
end
Thank you Wesley!
