Steps to building huge macroed things
basics
(* Moving during a recording WILL mess up your macro, even looking around will mess it up)
1- Set a ghost block down and remember it's initial position/rotation (in reference to your view, i.e. a slope facing towards you as a starting brick is a good option as it is easily remembered. If you plan on saving the macro, you can also include the starting brick and it's facing direction in the maccro title). This will the first brick you lay down at the beginning of the macro recording so make sure it's where you want it and facing in which direction you want it to face.
2- Hit record and start building the object (do not look around, keep the camera at the exact same angle at all times, do no strafe/move around. Like step 1 says, make sure you do not move/rotate the starting brick after you hit Record Maccro, as this will mess everything up. Where you placed the starting ghost brick before you started recording is where you will lay the starting brick once you begin recording )
3- Once you finished the object, stop the recording (After recording is complete, it's safe to move around).
4- Place the starting ghost brick on the ground, in the exact same angle/rotation as in step 1's brick (in our previous example, starting with the sloped brick facing towards you, the brick you set down when you want to begin the macro sequence should be the very same slope brick facing towards you), replay the macro to see if it works
Notes - Macro building depends on your View direction, not on it's original position on the grid. Say you made a minifig statue that's facing towards you (you built it, without changing camera view, the end result was the statue facing you), when you rebuild it using the macro, the statue will be rebuilt facing you yet again from you camera view perspective.
- Also, I highly recommend you avoid the use 2x2s or any other perfectly symetrical blocks to start the macro sequence with. This simply because when you're using the finished macro, you need to use the exact same starting brick with it's exact same orientation.
(This only really matters for macros that have slope bricks in them)
Say you start with a 2x4x1 (regular brick)
Original Macro N Bad Orientation S
Starting position ____ To begin the macro ____
|O O| sequence |O O|
|O O| |O O|
|O O| |O O|
|O O| |O O|
S N
Camera facing North
The difference between the block rotated so it's north face faces northwards and the one where it's rotated in the opposite direction is pretty easy to see in this illustration, however in blockland you can't tell which way it's facing (north side north or South side north? Who knows). This usually calls for Trial and error where you set the ghost brick, rotate it one way and try out the macro. If it succeeds, hurray, if it doesn't, set another ghost starting brick in front of you and try again this time rotating in the opposite direction. If it still doesn't work, then the problem lies elsewhere.
- Stuff your brick inventory with all the bricks you will need. Macros record the bricks you have in your inventory (Not sure if this is at the end or in the beginning, assume it's at the beginning) and then the macroing process will select the bricks from the inventory when you use the macro. (Macros using more than 10 bricks will need to be 2 seperated macros)
Hope this helps
