Enumeration Type Documentation

◆ Axis

enum Axis : uint8_t

Allow incrementing of DiagDirDiff variables.

Enumeration for the two axis X and Y

This enumeration represents the two axis X and Y in the game. The X axis is the one which goes align the north-west edge (and south-east edge). The Y axis must be so the one which goes align the north-east edge (and south-west) edge.

Enumerator
AXIS_X	The X axis.
AXIS_Y	The y axis.
AXIS_END	Used for iterations.
INVALID_AXIS	Flag for an invalid Axis.

◆ DiagDirDiff

enum DiagDirDiff

Enumeration for the difference between to DiagDirection.

As the DiagDirection only contains 4 possible directions the difference between two of these directions can only be in 4 ways. As the DirDiff enumeration the values can be added together and you will get the resulting difference (use modulo DIAGDIR_END).

See also: DirDiff

Enumerator
DIAGDIRDIFF_BEGIN	Used for iterations.
DIAGDIRDIFF_SAME	Same directions.
DIAGDIRDIFF_90RIGHT	90 degrees right
DIAGDIRDIFF_REVERSE	Reverse directions.
DIAGDIRDIFF_90LEFT	90 degrees left
DIAGDIRDIFF_END	Used for iterations.

Definition at line 95 of file direction_type.h.

◆ DiagDirection

enum DiagDirection : uint8_t

Enumeration for diagonal directions.

This enumeration is used for the 4 direction of the tile-edges.

Enumerator
DIAGDIR_BEGIN	Used for iterations.
DIAGDIR_NE	Northeast, upper right on your monitor.
DIAGDIR_SE	Southeast.
DIAGDIR_SW	Southwest.
DIAGDIR_NW	Northwest.
DIAGDIR_END	Used for iterations.
INVALID_DIAGDIR	Flag for an invalid DiagDirection.

Definition at line 73 of file direction_type.h.

◆ DirDiff

enum DirDiff

Allow incrementing of Direction variables.

Enumeration for the difference between two directions.

This enumeration is used to mark differences between two directions. If you get one direction you can align a second direction in 8 different ways. This enumeration only contains 6 of these 8 differences, but the remaining two can be calculated by adding to differences together. This also means you can add two differences together and get the difference you really want to get. The difference of 45 degrees left + the difference of 45 degrees right results in the difference of 0 degrees.

Note: To get this mentioned addition of direction you must use modulo DIR_END or use the ChangeDirDiff(DirDiff, DirDiff) function.

See also: ChangeDirDiff(DirDiff, DirDiff)

Enumerator
DIRDIFF_SAME	Both directions faces to the same direction.
DIRDIFF_45RIGHT	Angle of 45 degrees right.
DIRDIFF_90RIGHT	Angle of 90 degrees right.
DIRDIFF_REVERSE	One direction is the opposite of the other one.
DIRDIFF_90LEFT	Angle of 90 degrees left.
DIRDIFF_45LEFT	Angle of 45 degrees left.

Definition at line 58 of file direction_type.h.

◆ Direction

enum Direction : uint8_t

Defines the 8 directions on the map.

This enum defines 8 possible directions which are used for the vehicles in the game. The directions are aligned straight to the viewport, not to the map. So north points to the top of your viewport and not rotated by 45 degrees left or right to get a "north" used in you games.

Enumerator
DIR_BEGIN	Used to iterate.
DIR_N	North.
DIR_NE	Northeast.
DIR_E	East.
DIR_SE	Southeast.
DIR_S	South.
DIR_SW	Southwest.
DIR_W	West.
DIR_NW	Northwest.
DIR_END	Used to iterate.
INVALID_DIR	Flag for an invalid direction.
