[patch] Cargo Payment Fix (r27460)

[+] Spoiler

Time travel comparison at 24 km/h

Altered vehicle_base.h:
inline uint GetAdvanceDistance()
{
return (this->direction & 1) ? 128 : 256;
}


Original vehicle_base.h:
inline uint GetAdvanceDistance()
{
return (this->direction & 1) ? 192 : 256;
}



Time travel comparison at 3 km/h

Altered vehicle_base.h:
inline uint GetAdvanceDistance()
{
return (this->direction & 1) ? 128 : 256;
}


Original vehicle_base.h:
inline uint GetAdvanceDistance()
{
return (this->direction & 1) ? 192 : 256;
}

EDIT: I just noticed that OpenTTD isn't precise enough when doing calculations with very low speed values. Thus, these tests aren't all that good.

Best travel time approximation yet.


With attached patch:


Original 1.6.1:

Another alternative patch, vehicle income is modified, by basing it on penalized diagonal distances between source and destination tiles.

But road vehicles are adversedly affected by it, unfortunately.
