# Star Trek Doors - Normal and Split

Start out making five sectors, like the image here. The top and bottom sectors are the two rooms being joined. Set the Sector Lotag of the very middle sector to 9 for Normal Star Trek Door, or 26 for Split Star Trek Door. From here on out, I will refer to this as our "tagged" sector. This will become the door. The two sectors surrounding the tagged sector are entryways, so that the door has equal floor/ceiling heights on both sides to use as markers. |

Take grid-locking off and insert six vertices; three per white line of our tagged sector. The four points, marked by the little green arrows, must be kept in line with the door's red lines. We'll do this in the next step. |

We need to move the white line vertices we just inserted so they represent the shape of a door, one door on each side. Two catches when making Star Trek Doors: 1) the white lines of the door must be right on top of the red lines of its parent sector, and 2) you must have both halves of the door touching in the middle. What will happen in the game is this: the door will split open from the middle, the ceiling will raise to a neighbor, the floor will lower to that neighbor, and any void-player space (our door) will move to the sides. Hit 'G' in 2d mode to increment the grid spacing by one. We need to be perfectly inline with the red lines, and our two doors must meet in the middle. Move the vertices so they come close to the image.

Take it one step further and move the two points of the door halves so they share the same spot. They won't join into one... they will simply occupy the same place in Build. Insert a MusicAndSFX sprite in now before we get any further. This sprite must be located in the player space area. Set the MusicAndSFX lotag to 166, or any music number you prefer. The lotag represents both opening and closing sounds. |

Now is a good time to set the door's tiles. Switch over to 3d mode and set your tiles. Please note the tiles of our door will squish when the door opens. Our door is pretty small and will open very fast, so the player shouldn't notice anything unusual about the tile squishing. |

If you only wanted to make a Normal Star Trek Door, you could stop here. If you want to make a Split Star Trek Door, we still have another door left to handle... the door that splits from the middle and opens vertically. Luckily, there are no more sectors to add. The sector already exists... it is our tagged sector. Switch to 3d mode and point at the sector floor of our tagged sector. Raise the tagged sector's floor so it reaches the middle-height of the surrounding rooms. Change the floor tile to an appropriate door tile, and do the same for the tagged sector's ceiling. Now point at the tagged sector's ceiling and lower it as far as it can go; right down to the "floor", which is now in the middle of the room. Set the door's tiles, and you're pretty much finished. You'll probably want to have separately editable tiles for both the top half and bottom half of your door. Remember that to make them separately editable, you hit the number [2] when pointing at the wall.
