A curve laid anew, its radius changed or made compound, or a straight moved: the paths of the chain are cut again where their joints stood, set square onto the new line, each keeping its stretch of the ground, so their events, their track circuits and the cuts of the block sections stay where they were instead of being handed on along the line; the parts between the switches alike, the old even sharing kept where the joints don't follow one another along the new line.
The objects by a track taken for a change go with it by themselves: the signals and the warning discs it or its run reads, the SHP resonators by their events, and the controls of the block sections, the hectometre posts, the W17 markers and the other signs by the track nearest to them, within 12 m. They move square to the new axis keeping their offset and their turn, an object moved by hand meanwhile staying where it was put. Such a binding isn't kept in the scenery nor shown among the bound objects of the infra tool, which can still bind the object for good, and the undo and the redo take the objects back and forth with the tracks. The status of the Plan tells how many objects moved with the tracks. A path taking an object over the other way round keeps it on its side, turned as it was.
An error put in the status bar also shows for 4 s by the cursor, and the
refusals the tools kept in their panels (a curve which can't be laid,
a switch which doesn't fit, a signal which can't be moved, a drive
without the variant) go there as well.
Dragging an end of a straight refits the curve next to it with the cant
and the transition curves recommended for the speed, keeping the curve's
own only where it had some; a plain arc laid freely came out with
transitions. Break and S-curve took the recommended transitions too. The
recommendation of a design not checked against the norms is a plain arc
now, the tools take the norms in effect rather than the ones the design
was last computed with, and the Plan panel calls the automatic choice
"None" in the free design. Self-test: norms free|plk.
Esc in the middle of dragging a point of a track kept the moved point,
and the hint said so; dragging a straight was taken back but left an
empty step in the history; a vertex or the radius grip of a curve stayed
moved in the design. Now Esc puts back what was there before the drag in
all three, and the history doesn't keep a step for it.
Found with an address and undefined behaviour sanitizer build, random
monkey sessions on the test sceneries and broken inputs:
- A deleted model left its pointer in the pick list of the renderer, the
bound node of the panels, the bindings of the infrastructure and the
selection: the next pick or panel frame read freed memory. The renderer
forgets it, and one erase_model does the cleaning for all the places
which deleted a model by hand.
- The plan band of a route read the vertex before the first one in the
frame a drag was let go.
- A scenery which can't be opened goes back to the launcher with the
reason in the log, a track of an unknown type or a tributary loads as
a normal track or a river with a message, and a spline with no finite
length or step gets a sane number of segments.
- Typed numbers which aren't (NaN, inf, ends 0 m or 1000 km apart, a
vector of 1e30, a diverging track part of 5 km, a curve threshold of 0,
a zero history size, radius norms below zero) are refused or clamped,
where they made the geometry run away or divide by zero.
- Folders which can't be read and file names which aren't valid in the
locale no longer throw out of the scans of sceneries, textures, sweeps,
roads and signal plates; the scans skip them.
- The launcher: Ctrl+Del with no trainset selected, a dropped vehicle
whose skin is gone and a text with a percent sign.
- A terrain mesh made for another resolution of its chunk isn't put into
the chunk, and a slot is reused only for a mesh of the same size.
- Vehicles on a track changed by the editor are moved over a copy of the
list they leave.
- The table of the keyboard shortcuts gives its stretched column a
weight, else ImGui divides 0 by 0 in the first frame of the window.
Labels:
- every button, field, tooltip and message of the editor reread for a beginner: short nouns for the fields with the
sentence in the tooltip, the less used options under More settings, one glossary (field of work, template, track,
grade), sides told from directions, degrees and per mille as signs, messages built from one format string
- plural forms through STR_P; the last entry of a po file is read too, and the Polish plural rule is in the header
- lang/editor_pl.po: the code pass entries merged, 391 entries no code uses and 3 duplicates dropped
- roads: the notes and errors naming a road translated; the build options and the layout fold the texture length,
kerb sizes, traffic share, roundabout part, height over the ground and junction speed limit under More settings, the
lanes start folded
Grade lines fitted to the terrain model (NMT), a line or the whole scenery at once:
- fit_ground: a robust fit on nodes 5 m apart; the ground parting from the line (a bridge, a viaduct, a wall) is gone
past rather than followed, the bends keep off the switches as far as their curves reach, a run of bends the same way
is one point of intersection, a curve with no room is as sharp as the room lets it be
- the ends of the line and the other paths of its switches leading into lines fitted already bound the line by what
the tracks between can climb; ends meeting in the plan, laid apart in height by hand, are joined before the run
- apply_profile: the paths are split where split_path takes the parameter (a straight was cut in the wrong place, into
pieces of a few centimetres the game takes for zero length), no piece shorter than the margin; the paths off the
ends of the route are brought to its height
- Bytom: 1600 lines, grade breaks at the joints 89 -> 20; Tarnowskie Gory: 848 lines, 223 -> 3; no step over 2 cm
- editormoderoute.cpp: the route design, its kept records and digitizing
- editormodestraights.cpp: the plan tool: straights, the detour, the curve fit
- editormodelay.cpp: laying track, free ends and extending, the build tools
- editormodeswitchplace.cpp: placing switches, crossovers and links, double slips, curved switches
- editormodetrack.cpp keeps the selection, the snapshots, the tabs, the inspector and the path panel, the hints
- the sizes of the handles and reaches and the small helpers they all use in editormodetrackshared.h
The code is moved as it was.
