ik heb mijne nog steeds niet fullscreen in win2k, maar het schijnt dat je dat met een of andere tool van de win2k cd wel kan doen, maar dat moet ik nog proberen.
Dit repliede Josef Drexler iig over de nieuwe pre-signals:
There's a very brief description on them on the TTDPatch source code page,
but I guess some more explanation would be useful.
Basically there are two options for pre-signal setups:
- automatic (presignals on or -w)
- manual (extpresignals on or -Xw)
Any combination of these two settings is valid, i.e. you can have only
automatic settings, or only manual (using the Ctrl-key to change the
signal), or both, or neither.
Automatic pre-signals converts regular signals into pre-signals if the
conditions stated in the manual are met. Basically: a one-way signal
leads to several two-ways, which in turn lead to a end-of-line or another
one-way. This conversion happens whenever a train enters the block. The
game will never change the configuration of a signal that has been set
manually, you can even force it to remain a regular signal.
Note that if you have ttdpatch.grf, signals with a yellow, horizontal bar
are pre-signals, signals with a grey, vertical bar are pre-signal exits,
and signals with a yellow, vertical bar are combined pre-signal and
pre-signal exits. Otherwise you can find out using the info tool.
Now, the principle how pre-signals work is actually quite simple:
"A pre-signal is green if at least one of its pre-signal exits is green."
You place a pre-signal, and behind it you mark a few signals as
pre-signals exits (or have this done automatically). Then the pre-signal
will only show a green light if one of the exits shows one too. This can
be used to make a train wait at a junction where it has a choice, until
one of the choices becomes available. Until then it'll wait at the
pre-signal. Note that regular two-ways that are not marked as exits will
not make a pre-signal go green, only actual exits count.
A slight complication are combined signals, which are both a pre-signal
and an exit to a prior pre-signal. These can only be placed manually, and
will not appear in automatic setups. You can use these for a setup like
this: (look at this in a fixed-width font)

Here, you have two station entrances, from the left and right. Each has a
separate pre-signal "P", and two normal exits "E". In addition, there is
a combined two-way signal "C", which functions as an exit for each
pre-signal, and is itself a pre-signal for both directions.
This setup allows trains from both direction to enter the station
simultaneously, and it also allows a train to enter the *other* section if
all of its own signals are red but some are green over there.
Basically, the pre-signals "P" are green if *any* of the four exits are
green, yet they form two separate blocks to allow two trains to enter the
station simultaneously, if both have some available platforms.
There are also some more exotic setups in which the combined signals might
be useful, but this seems to be the main application. I'd love to hear if
anyone can think of other useful ways, or perhaps even an idea how to
improve them further.
