Undo (Middle click?)

Sionide · Post by **Sionide** » 15 Feb 2005 19:28

Doesn't it really annoy you that if you're building a track and you make 1 mistake, you have to then go all the way up to demolish/remove that one little piece of track??

Wouldn't it be a good move to have the middle mouse button as an "Undo" type button, if you're building, accidentally make a piece of track going the wrong way, just middle-click and it undoes what you just did??

Perhaps a keyboard shortcut too?

When you're using the autorail tool, ctrl-click removes the highlighted track...

Once I got used to autorail, I don't use the other rail build tools any more.

ah cool - didn't know that, but still - the middle click doesn't do anything as of yet, i think it'd be good for an overall Undo-last-action thing?

R activates the bulldozer

How about middle clicking acting permenantly as the bulldozer? Would be super handy imo cuz I can't always be bothered to mess around looking for keyboard shortcuts and switching between bulldozer and autorail all the time with the mouse is too much hassle

I'm thinking something similar to rollercoaster tycoon's right clicking to remove stuff, but also with support for dragging like the normal bulldozer.

And yes you are looking at the most lazy computer user ever

Actually numerous different keys activate the bulldozer depending on which build menu you have up. Hopefully they'll fix it and make it consistant one day.

Well, I think having the middle mouse as undo (or the bulldozer) is a cool idea.. It would help alow.. Well, not A LOT, cos it doesn't take much to move your hand a bit but still, it'd be cool.

There's an important difference between "bulldoze" and "undo". With "undo" you should also get your money back - everything should be like it was a couple of seconds ago, with "bulldoze" you might get money back for clearing landtiles, but you've lost the building costs.

I'd like to see an undo button (either with a convenient shortkut-key or not). It happened twice to me yesterday that I accidently built a road-bridge instead of a rail-bridge; had to demolish the wrong bridge and in the end pay for two bridges instead of one. (Instead of a complete undo, a button that changes a bridge-type from rail to road or back would be nice as well).

A bit off-topic: is there somewhere an overview of all keyboard-shortcuts of openTTD? I searched a bit, but couldn't find one

i would like an undo function.

oops, just wated my money demolising the ocean

I WANT MY MONEY BACK! UNDO! UNDO!!!

atleast the remove track function is good.

an undo wouldn't work in multiplayer though.

true. I guess it's hardly no extra coding work to make the undo button optional; and set the undo for multiplayer off as default

There is an undo function. It's called a savegame. The only safe way to revert to a previous state is to revert everything, and making a savegame everytime you change something is abusurd.

Besides, how much game-time do you spend where the cost of undoing your mistake and fixing it is actually significant?

I didn't know that implementing an undo option by the coders could only be done by saving after each build-operation. Nevermind then..

no it doesn't, it just has to remember the last thing you did.

It wouldn't break anything in game if undo would simply bulldoze\remove last structure made (bulldoze track\remove signal) - of course it will cost some money...

Post by **WWTBAM** » 19 Oct 2005 08:50

but thats what the buldozer is for they want an undo option if they make a lousy click that doesnt cost anything

MeusH · Post by **MeusH** » 19 Oct 2005 08:57

Imagine one placing airport to block competitor from building track... After a month of idling he undoes what he did, and he also gets money back... Bad idea.
Only way to make undo acceptable would be just paid bulldozer.

maybe we could hve it detect what was next to it and check if any new road (mainly rail) faceing it appears and if it does and has nothing using it of the company who built it then they cant remove it.

But what if presence of the signal has caused two trains to enter what will become a single block?
And for track, what if a train is on that track?
For depots, what if a vehicle is (partway) in?
Even if you just use the checks that are already in place, this just makes the undo function a glorified bulldozer.

To do undo properly, you'd have to maintain an undo stack, and check the whole thing every time a vehicle does something that could invalidate an entry. (Enters a new tile, changes target, &c.)

Like I said. There's an undo function: a savegame. The bulldozer tool works pretty well too, but obviously isn't entirely an undo.

the idea is great, but my mouse doesn't have a third button. It does have a wheel though, and it is clickable. does that count as the third button?

Hmmm... I believe it does in lots of games. But when you press it you might accidentally scroll too, which usually has another effect in games.
