|
|
// o First build it using temporarily the same control group of the previous (non-tower) piece
|
|
// o Set the previous piece's secondary control group to the tower's entity ID
|
|
// o Restore the primary control group of the constructed tower back its original (unique) value.
|
|
// The temporary control group is necessary to allow the newer tower with its unique control group ID to be able
|
|
// to be placed while overlapping the previous piece.
|
|
//
|
|
// SECOND PASS:
|
|
// - Go end to start from the last successfully placed wall piece (which might be a tower we backtracked to), this
|
|
// time registering the right neighbouring tower in each non-tower piece.
