Detailed Description

This struct contains all the info that is needed to draw and construct tracks.

Definition at line 127 of file rail.h.

Member Function Documentation

◆ GetRailtypeSpriteOffset()

uint RailTypeInfo::GetRailtypeSpriteOffset ( ) const
inline

Offset between the current railtype and normal rail.

This means that:

1) All the sprites in a railset MUST be in the same order. This order is determined by normal rail. Check sprites 1005 and following for this order

2) The position where the railtype is loaded must always be the same, otherwise the offset will fail.

Definition at line 295 of file rail.h.

Field Documentation

◆ 

struct { ... } RailTypeInfo::base_sprites

Struct containing the main sprites.

Note
not all sprites are listed, but only the ones used directly in the code

Referenced by DrawTile_TunnelBridge().

◆ grffile

const GRFFile* RailTypeInfo::grffile[RTSG_END]

NewGRF providing the Action3 for the railtype.

nullptr if not available.

struct { ... } RailTypeInfo::gui_sprites

struct containing the sprites for the rail GUI.

Note
only sprites referred to directly in the code are listed

Referenced by BuildRailToolbarWindow::OnInit().

◆ introduction_date

TimerGameCalendar::Date RailTypeInfo::introduction_date

Introduction date.

When #INVALID_DATE or a vehicle using this railtype gets introduced earlier, the vehicle's introduction date will be used instead for this railtype. The introduction at this date is furthermore limited by the introduction_required_railtypes.
