#define STRAIGHT_TRACK_LENGTH 7071/10000 |
Approximation of the length of a straight track, relative to a diagonal track (ie the size of a tile side).
#defined instead of const so it can stay integer. (no runtime float operations) Is this needed? Watch out! There are no brackets around here, to prevent intermediate rounding! Be careful when using this! This value should be sqrt(2)/2 ~ 0.7071

typedef int32 TileIndexDiff |
An offset value between to tiles.
This value is used for the difference between to tiles. It can be added to a tileindex to get the resulting tileindex of the start tile applied with this saved difference.
