This page contains information on industry properties, variables and callbacks. Industry tiles are closely related.
Industry ID allocation
Industry IDs are local to the NewGRF, you are free to choose any ID in the 0..127-range. You should start your item definition with the 'substitute'-property, which allocates a new industry. The value of this property should be the ID of a default industry, which will be used instead of your item if it is not available for whatever reason (for example, missing NewGRF).
Furthermore, you can set the 'override'-property, which will cause the existing industry to be replaced with your item. You should use this if you are for example defining a coal mine which changes production more dynamically. If your type is not a direct replacement of an existing item, don't set this property.
Industry properties
Industry properties. Default industry type numbers can be found at default industries.
property | value range | comment |
---|---|---|
substitute | industry type | Number of the original industry type that replaces this one, should it not be available for some reason (e.g. missing NewGRF). This property must be set first, before any other properties or graphics. All properties of the old type are copied to your new industry. |
override | industry type | Number of the original industry type overridden. This will cause other grfs / industries to consider your industry type the same as the old type. Only set this property if your type is (more or less) the same as the old type. |

To follow the "<Town Name> <Industry Name>" convention, the string should include a "{STRING}" at the position the town name shall be inserted. For example: STR_HARBOR_NEARBY_NAME :{STRING} water side |
Cargo types array
The cargo_types property takes an array of accept_cargo and produce_cargo expressions. This array is used to define which cargo types the industry accepts, which it produces, and how much cargo is produced on production ticks and on delivery. All cargo types the industry handles must be mentioned in its cargo_types property even when they are handled by production callbacks.
The following is an example of a cargo_types property:
cargo_types: [ produce_cargo("GOOD", 4), accept_cargo("PASS"), produce_cargo("PASS", 0), accept_cargo("IORE", produce_cargo("STEL", 1), produce_cargo("SLAG", 0.25)) ]
The above example has four items in its cargo_types array, two produce_cargo expressions and two accept_cargo expressions.
produce_cargo("GOOD", 4)
specifies the industry produces GOOD at a rate of 4 every production tick (256 game ticks), this production rate is scaled by the industry's production level.accept_cargo("PASS")
specifies the industry accepts PASS as a "black hole", that is no cargo is produced when PASS is delivered. If you have a production callback that consumes a cargo you will also need to specify that cargo in this way.produce_cargo("PASS", 0)
specifies the industry produces PASS but not on the production ticks as usual. Specifying a production rate of zero is only useful for cargo types you produce via a production callback.accept_cargo("IORE", produce_cargo(...), ...)
specifies the industry produces the listed cargo types every time IORE is delivered. In the example above, delivering one IORE will result in one STEL produced and no SLAG produced (because 1*0.25 is zero after rounding down), and delivering 4 IORE will result in 4 STEL and 1 SLAG produced.
At most 16 different cargo labels may appear in accept_cargo and at most 16 different cargo labels in produce_cargo, for a single industry. The same cargo label can be used in as many accept_cargo or produce_cargo as necessary.
More complex production rules can be set up via the production callbacks, see callbacks below.
Industry special flags

Variables that require some parameters.
name | arguments | comment |
---|---|---|
industry_count | industry_type, grfid = -1 |
The value of this variable is the number of industries of a given type that are currently on the map. industry_type is either the ID of an industry. GRFid is the grf in which the industry was defined. The default value is -1, which means current newgrf. A grfid of 0 lets you check the number of default industries of a given type. Use the builtin function |
industry_distance | industry_type, grfid = -1 | The value of this variable is the manhattan distance the closest instance of the given industry or 0xFFFF if not applicable.

Industry callbacks
callback | return value | comment |
---|---|---|
default | varies | Any unhandled callbacks. Generally this doesn't need to be used, except for old-style callbacks. |
produce_cargo_arrival | Produce-block | Called to produce cargo when it arrives. |
produce_256_ticks | Produce-block | Called to produce cargo every 256 ticks. |
availability | CB_RESULT_IND_ALLOW or CB_RESULT_IND_DISALLOW |
NML 0.2 Only available in NML 0.2 or earlier. Called when the game needs to know if the industry type is available. It is limited to the type as a whole, so you can't access industry-specific variables. |
construction_probability | CB_RESULT_IND_NO_CONSTRUCTION, CB_RESULT_IND_PROBABILITY_FROM_PROPERTY or a relative probability 0..255 |
NML 0.3. Called when the game needs to know if the industry type is available. It is limited to the type as a whole, so you can't access industry-specific variables.
If you return CB_RESULT_IND_NO_CONSTRUCTION or 0 the industry won't be build. If you return CB_RESULT_IND_PROBABILITY_FROM_PROPERTY it'll be build according to the relative probability as defined in the |
location_check |
See the table below. |
Called to check if a location is suitable.
Since the industry isn't built yet, industry variables aren't available. If this callback is not implemented or fails, constructing the industry will be allowed. Construction might also be prevented via the |
monthly_prod_change |
See below |
Called each month to (possibly) change the industry production.
|
random_prod_change |
See below |
Works exactly the same as monthly_prod_change , except that it's only called when TTD selects this industry for a random production change.
|
build_prod_change | Value in range 4-128 | 1.3 Called when an industry is constructed. Return value is production level (default 16). Can also be used to initialise permanent storage when an industry is constructed. |
cargo_subtype_display | String, CB_RESULT_NO_TEXT or CB_RESULT_IND_NO_TEXT_NO_AMOUNT | This callback allows displaying some text after a cargo name. Returning
Note: To remove cargo waiting text, return If IND_FLAG_LONG_CARGO_TYPE_LISTS is not set:
If IND_FLAG_LONG_CARGO_TYPE_LISTS is set:
|
extra_text_industry | String | Show extra text in the industry window. |
extra_text_fund | String | Show extra text in the fund window. Since the industry isn't built, no industry variables are available. |
control_special | 0 or 1 | Called to control various effects from the spec_flags property. Currently only works for the first two (plant fields / cut trees). Return 1 to execute the action or 0 to not do so.
The default (if the flag is enabled, of course) is to plant fields with 1/8th chance every 256 ticks, and to cut trees every 512 ticks. |
stop_accept_cargo | 0 or 1 | With this callback, you can temporarily refuse accepting a certain cargo, for example because the stockpile is full. Return 1 to accept or 0 to refuse. Make sure to synchronize this callback with the cargo_amount_accept callback for industry tiles.
|
colour | COLOUR_XXX | Called after constructing the industry. The colour variable is set to a random value at this point, you can use this callback to change this.
|
cargo_input | Cargo type, or 0xFF | Decide the input cargo types, called when the industry is built. Called repeatedly until 0xFF is returned, although currently not more than three times. Do not rely on this limitation, though.
Return a cargo type (from the table) or 0xFF to stop. |
cargo_output | Cargo type, or 0xFF | Same as cargo_input above, except that it is applied to the output cargo types and currently not called more than twice.
|
