A vehicle's picture needs eight pictures : one for each direction of the vehicle (North, North-East, East, South-East, South, etc …). Symmetrical vehicles would have same pictures twice (same North and South for example). Vehicles can have different length : each length unit is four pixels in Noth, South, East and West pictures. For diagonal pictures it's a decimal number so the two extremities of the pattern chosen for a defined length will be on each other. This is the graphical pattern :
The default length is 8 (32 pixels) if you don't define it in the .dat file. On this pattern, each length is made of a different grey, to use this pattern, take the necessary line according to the way type, delete, thanks to replace color tool and playing on the tolerance, the greys until the right length of the vehicle. The pink unit is the default length (8). The light grey is the front of the vehicle. The background of this picture is the trensparency color for Simutrans. For suspended monorails, the pattern doesn't show the base of the vehicle but its roof.
This is the .dat pattern according to the graphical pattern for a vehicle or the empty graphic of a vehicle : (x = number of the line, name = name of the source picture witheout .png extension)
This is the parameters for a vehicle :
| Parameter | Description | Content | Example |
|
| obj | object type | vehicle | ||
| name | name | text | SNFOS_Aero_front | |
| waytype | way type | internal name | maglev_track | |
| cost | price (*100c) | number | 5000000 | |
| weight | weight (t) | number | 35 | |
| runningcost | running cost (0,01c/km) | number | 90 | |
| engine_type | energy used | internal name | fuel_cell | |
| speed | max speed (km/h) | number | 550 | |
| freight | freight content | internal name | Passagiere | |
| payload | quantity of content | number | 65 | |
| power | power (kw) | number | 4200 | |
| gear | gear (*0,01) | number | 100 | |
| intro_year | introduction year | number | 2019 | |
| intro_month | introduction month | number | 11 | |
| retire_year | retire year | number | 2039 | |
| retire_month | retire month | number | 11 | |
| smoke | smoke | internal name | steam | |
| sound | sound at starting | see below | 0 | |
| length | length of the vehicle | number | 8 | |
| copyright | name of the creator | text | Gauthier | |
| Constraint | see below | |||
The gear allows to keep the real power of a vehicle and then multiply it in the game so the vehicle can be used normaly.
ingame power = power
Example : if a 800 kw powered vehicle is reproduces but this power isn't sufficiant for the vehicle to be used, a gear > 100 (1) is added, for example 130 (1,30).
This parameter defines which vehicle can be placed before and which vehicle can be placed after a vehicle. If it's not defined, the vehicle can be placed before or after any vehicle witheout constraints.
There's one possible vehicle per line, a constraint line is written as this (example) :
Prev : vehicle can be placed before
Next : vehicle can be placed after
0,1,2,3,… : it's necessary to order constraints Prev and Next by giving them a number, example :
Constraint[Prev][1]=vehicle2
Constraint[Prev][2]=vehicle3
Constraint[Next][0]=vehicle4
The content can be the name of a vehicle (the name of the paramter “name” of the chosen vehicle) or “none” so nothing can be put before or after the vehicle. “none” must be placed at the last in Prev or Next constraints, makeobj stops reading them when it reads “none”, if vehicles are placed after, they won't be cared. If a vehicle has not a “none” it will be necessary to place a vehicle before or after.
For a vehicle to be put after another, the first vehicle must be in Constraint[Prev] of the second one which must be in the constraint[Next] of the first one.
Example of constraint (SNCF_z22500_ZRBx_front)
Some vehicles, almost freight ones, have a different picture when they are empty or loaded. This is the necessary parameters, for example with two different freight images for two different goods :
freightimage[0][S]=image.x.2
freightimage[0][E]=image.x.0
freightimage[0][SE]=image.x.1
freightimage[0][SW]=image.x.3
freightimage[0][N]=image.x.4
freightimage[0][W]=image.x.6
freightimage[0][NW]=image.x.5
freightimage[0][NE]=image.x.7
freightimage[1][S]=image.x².2
freightimage[1][E]=image.x².0
freightimage[1][SE]=image.x².1
freightimage[1][SW]=image.x².3
freightimage[1][N]=image.x².4
freightimage[1][W]=image.x².6
freightimage[1][NW]=image.x².5
freightimage[1][NE]=image.x².7
First goods are defined using their internal names. The used number is put in brackets. Then the graphical pattern of the base picture of a vehicle can be used here if you use freightimage[n°] instead of EmptyImage. In the example below, freightimage[0] are for the vehicle loaded with good1 and freightimage[1] is for the vehicle loaded with good2. x and x² are the number of the lines of these pictures.
Example with bullk wagons of Cirrus :
Comme exemple concret nous allons refaire l'avant de l'AGV donc voici les graphismes :
Nous allons utiliser la trame graphique donnée plus haut, l'AGV étant un train nous utiliserons la ligne “track/MLM”. Prenez-là avec prcision sur la trame et faites-en une nouvelle image “AGV.png”. Voici donc cette image :
Supprimez le cadre rouge et le texte “track/MLM”. Ensuite sachant que l'avant d'AGV a une longueur de 11, supprimons les longueurs en trop pour n'avoir que 11 longueurs. Etant donné que la trame est faite à partir de niveaux de gris, on peut utiliser l'outil de remplacement de couleur de photofiltre.
En jouant sur la tolérence on supprime facilement les carrés en trop.
Ensuite afin de changer le reste de la trame en une couleur unie et repérable (pour la supprimer facilement une fois le véhicule placé), on utilise l'outil baguette magique avec tolérance 0 sur le fond, on inverse la sélection pour n'avoir dedans que la trame, après avoir mis du rouge en couleur secondaire on supprime, en s'étant assuré d'avoir supprimé le lissage des sélections.
On obtient ainsi une trame exploitable pour un véhicule ferroviaire de longueur 11 :
Il ne reste plus qu'à placer nos images d'AGV comme ceci :
Ensuite on supprimer les morceaux de trame en trop avec l'outil remplacer les couleurs et voila l'image source :
Attaquons maintenant au .dat de cet avant d'AGV ! Pour commencer mettons la partie graphique du .dat à partir de la trame vue plus haut :
Faisons les remplacements adéquats sachant que notre image se nomme AGV.png et que la ligne de l'avant est la ligne n° 0 (la première ligne) :
Ensuite il suffit d'ajouter les données de l'AGV. Pour les constraints on sait que l'avant d'AGV doit pouvoir se placer derrière rien (pour un avant de convoi), derrière un arrière d'AGV (pour les unités multiples), on doit pouvoir placer derrière cet avant d'AGV une voiture à pantographe avant. Voila le résultat final :
