Badge properties

property	value range	comment
label	string with / as delimiter	For sake of compatibility and user experience, consider using labels already introduced by other NewGRFs. Badges with label without / are considered to be classes. Labels for other badges should match following syntax: "label_of_class_they_belong_to/label_for_the_badge"
name	string	Name of this badge or badge class.
flags	bitmask(BADGE_FLAG_XXX, ...);	COPY_TO_RELATED_ENTITY Badge can be copied to related entity (e.g. badge on a railtype can be copied to rail vehicles of that railtype.) NAME_LIST_STOP Stops adding more names to the visible name list. NAME_LIST_FIRST_ONLY Add this name to the visible name list only if this is the first name. USE_COMPANY_COLOUR Recolour badge depending on company that player currently controls. NAME_SKIP Allow the badge to be excluded from the badge name list.

Badge variables

name	value range	comment
intro_date	date(yyyy, mm, dd)	Introduction date of entity (or current date if entity type does not have an introduction date). See introduction_date in vehicle properties.

Badge callbacks

Note: By design badges are meant to only be up to 12 pixels tall.

callback	return value	comment
default	spriteset	Graphics for the badge or badge class.
aircraft airports airporttiles houses industries industrytiles objects railtypes roadstops roadtypes roadvehs ships stations trains tramtypes	spriteset	Override default graphics when used by other specific feature.

Prerequisites

Badges require a badgetable to be defined for most common usage scenarios (eg to refer to a badge from an item block). This is not a hard requirement and can be omitted if you are, for example, creating badges that other newGRFs can later refer to

Eg for power/diesel to be used in the badges property for a vehicle, the badge table must contain entries for both power and power/diesel

Example code

 badgetable {
     "power",
     "power/diesel",
     "power/steam"
 }

item (FEAT_BADGES, power) {
    property {
        label: "power";
        name: string(STR_POWER);
    }
}

# This badge will not show a sprite in the purchase menu
item (FEAT_BADGES, diesel) {
    property {
        label: "power/diesel";
        name: string(STR_POWER_DIESEL);
    }
}

# This badge will show a sprite in the purchase menu
item (FEAT_BADGES, steam) {
    property {
        label: "power/steam";
        name: string(STR_POWER_STEAM);
    }
    graphics {
        default: sprite_steam;
    }
}
