OK, a small help from me... the templating system explanation.
Sprite #1 - engine going up - aligned always to the top
Sprite #2 - engine going up+right - aligned always to the bottom right + 1px upwards for every 1px shorter sprite (i.e. lenght 8/8 is aligned to the bottom, 7/8 is 1px up, 6/8 is 2px up etc.)
Sprite #3 - engine going right - aligned always to the bottom right
Sprite #4 - engine going down+right - aligned always to the bottom right
Sprite #5 - engine going down - aligned always to the bottom
Sprite #6 - engine going down+left - aligned always to the bottom left
Sprite #7 - engine going left - aligned always to the bottom left
Sprite #8 - engine going up+left - aligned always to the bottom left + 1px upwards for every 1px shorter sprite (i.e. lenght 8/8 is aligned to the bottom, 7/8 is 1px up, 6/8 is 2px up etc.)
Also, there are 4 separate templates for locomotives
- as explained in pic #1 below:
Pic1.PNG [ 13.58 KiB | Viewed 21561 times ]
Purchase menu sprites are ALWAYS included at the bottom of these templates.
As for passenger/mail coaches
, there is only one template looking like this:
Pic2.PNG [ 11.29 KiB | Viewed 21561 times ]
99,99% of pax/mail coaches has only the first row as they look always identical, loaded or not. Indian coaches have people hanging out from windows and doors and sitting on the roof and these sprites have different loading stages and therefore occupy all 3 rows of the template.
As for 4 variants - the idea is that the first variant receives 60-70% chance of appearing when buying the coach, others appear in the remaining 30-40% (10-15% each). Their stats do not differ, this is for eyecandy purpose only. This is a random effect that cannot be influenced in any way other than buying and buying coaches until you get what you want. (i.e. You want 10 variant-3 coaches? Buy coaches until you get 10 of them and then sell the others...)
Also - passenger/mail coaches have their P-menu sprite in a SEPARATE FILE, usually named as <coach name>-P.png.
have only two templates - one is the same as pax/mail coaches (with 3 rows), the other template has 4 rows.
1st row - empty wagon - driving/loading sprites
2nd row - half-full wagon - driving/loading sprites
3rd row - full wagon - driving/loading sprites
4th row (if applicable) - driving sprites - if wagon i.e. opens doors when loading then these are sprites with closed doors meant for travelling
4 variants - same as for pax/mail coaches
P-menu sprite - same as for pax/mail coaches
EDIT: I forgot - freight wagons have a separate file for EACH CARGO!
