📋 About This Mod

WHAT IS THIS

Workshop constructible Access Hatch, allows you to literally climb through the roof.

Easily access previously hard to get to rooftops. No need for a stairwell, just go straight up.

Don't understand?

You put The Access Hatch (128 Units) inside Red Rocket:

And when you use the hatch to climb on the rooftop, it then looks like this:

The Access Hatch is one workshop buildable piece.

You activate it from below - You move up. You activate it from above, you move down.

Understand now?

SO WHAT'S IN IT THEN AND WHERE?

  • []There's a whole bunch of different hatch lengths: 16, 32, 48, 64, 96, 128, 256 Units.[/]

    []Select one depending on how thick a roof or upper floor you need to pass through, or how deep underground u wanna go.[/]

    []There is a snappable ladder extension piece for the hatches.[/]

    []Also door and tunnel pieces: 32, 48, 64, 128, 256, 1024 and 2048 Units length.[/]

    []Use those to pass through walls or to dig into hillside terrain.[/]

    []All the pieces are in the STRUCTURES/CONCRETE/MISC build menu.[/]

    ANYTHING TO KEEP IN MIND?

    • []Hatches do not have a load screen.[/]

      []Tunnels and Doors have a load screen, simply because of an engine level problem.[/]

      []This bug prevents your char from jumping, but only seems to trigger when there is cell water close by the tunnel/door.[/]

      []Tunnels and door pieces therefore operate in "SafeMode" by default.[/]

      []SafeMode works around the cell water bug, at the cost of introducing said load screen.[/]

      []To disable SafeMode for a particular piece that you trust or know is not going to be affected by said bug, select the Tunnel/Door in console and type:

      setpv SafeMode false[/]

      []This disables SafeMode for the selected piece and there won't be a loadscreen anymore.[/]

      []Using true instead of false will reenable SafeMode on it.[/]

      []If you get affected by the bug while experimenting, simply pass through a SafeMode enabled door or tunnel to fix it.[/]

      BUT WAIT, THERE'S MORE!

      []The hatches auto-place on workshop roofs and upper floors. Place them from below while buildiing.[/]

      [*]Place Everywhere highly
