[SOLVED] Automatic X/Y/Z positioning in attachElements

[myonlake]

Hello,

I am trying to find a script that automaticly positions my createObjects to attachElements so that I don't need to configure them myself. It's annoying when you need to position every object, takes a lot of time.

EDIT:

I solved the problem

Alright, so the fix is that when you do attachElements, you MINUS the position from the original position of the source object. Like this.

  
local originalX = 100 
local originalY = 100 
local originalZ = 1 
  
local example1 = createObject... 
local example2 = createObject... 
  
attachElements(example1, example2, 1000 - originalX, 1000 - originalY, 5 - originalZ)

know its solved, but i believe this is more of a solution(as rotation changes the axis direction)

function calculateOffsets(slaveElement, masterElement) 
    local px, py, pz = getElementPosition(slaveElement) 
    local vx, vy, vz = getElementPosition(masterElement) 
    local sx = px - vx 
    local sy = py - vy 
    local sz = pz - vz 
    local rotpX, rotpY, rotpZ = getElementRotation(slaveElement) 
    local rotvX,rotvY,rotvZ = getElementRotation(masterElement) 
    local t = math.rad(rotvX) 
    local p = math.rad(rotvY) 
    local f = math.rad(rotvZ) 
    local ct = math.cos(t) 
    local st = math.sin(t) 
    local cp = math.cos(p) 
    local sp = math.sin(p) 
    local cf = math.cos(f) 
    local sf = math.sin(f) 
    local z = ct*cp*sz + (sf*st*cp + cf*sp)*sx + (-cf*st*cp + sf*sp)*sy 
    local x = -ct*sp*sz + (-sf*st*sp + cf*cp)*sx + (cf*st*sp + sf*cp)*sy 
    local y = st*sz - sf*ct*sx + cf*ct*sy 
    local rotX = rotpX - rotvX 
    local rotY = rotpY - rotvY 
    local rotZ = rotpZ - rotvZ 
    return x, y, z, rotx, roty, rotz 
end
