In other words, if I have landfill and necessary materials on hand us personal bots, when I place a blueprint it just gets built (all the hoops handled behind the scenes).

Since it has already been made, yes it is feasible. It adds a button that is visible while placing a blueprint that adds landfill under all entities in the blueprint (or temporary cut-copy-paste blueprint) and also the ability to flip blueprints etc.
There's another mod that just adds that button but it adds the button permanently even when not holding a blueprint and it lacks the other features so I wouldn't recommend it over BlueprintExtensions, which is a must have. But BP-E was broken a while back so then I used the worse mod as a temporary replacement.

You have to press the button first though and you might have to double-click (a vanilla bug maybe?) to get entities placed on top of landfill ghosts to actually stick. But it's pretty much perfect and that's just a really minor inconvenience.

zOldBulldog wrote: Thu May 16, 2019 6:01 pm From the discussion it is now clear to me that the ability of being able to undo comes at a heavy price... having to use a landfill tile that is non-standard and therefore if you uninstall the mod you end up with a broken map or have to go through a number of difficult hoops to prevent it.

This sounds like a great idea, actually I can't think of any reason not to make this change.

Let me see what I can do

So get Platforms because soon they will be undoable landfill with no drawback.

how do you intend to detect "holding shift", i'm not aware the engine supports anything other than "pressed down once"?

You're right, can't be done. A shame

Do you need to? on_put_item gives you a blueprint placement event (might not happen when not forced but then it doesn't matter really in this case). So instead of adding it when you press shift, do it when you place the item. And you don't even have to modify the actual blueprint. You can modify a copy that you swap in and then back out on placement instead. Check out how BlueprintAlignment mod does it. You can't undo (not added to the undo stack) when a blueprint is aligned. But I think BlueprintAlignment could avoid that issue by not calling build_blueprint and instead swap in a modified blueprint in hand (it swaps in a dummy object to avoid regular placement completely and builds it by itself instead, which is bad with the way build_blueprint currently works). So you could make it work too

I thought i observed the other day that this doen't fire at all if none of the blueprint content can be placed (i.e. all is over water). Maybe i'm remembering that wrong?
