NewGRFs only use a small subset of the available language IDs. Using an unordered_map allows only the reference languages to have space allocated.
This avoids manual new/delete of array.
Always treat empty groups as non-equal. Given that the case of both being empty is handled earlier, they cannot both be equal and empty.
Additionally if a loaded or loading set are all the same, only add one reference.
Standardises how the class index is stored in the spec, instead of relying ot the Spec structs having the same members.
This allows retrieving class_index and index without searching or using pointer arithmetic.
'cls_id' is renamed to 'class_index' to make it clearer that it is an index rather than the multichar label of the class.
Simplify AirportSpec data by storing layout information together in a vector, instead of separate arrays.
This removes manual memory management and separate count members.
The default layouts will be copied instead of always referring to the originals.
Use a vector to store the list of random sounds played for an industry.
The removes manual memory allocation, flags to control memory management, a separate count member, and a try/catch block.
Default cargo label was not cleared (set to CT_INVALID) when using older 3-slot acceptance properties for house and industry tiles.
Missed in #12053 and #12062.
Using Action A above the baseset is error prone as the sprites are not fixed and can be moved around.
Any NewGRF doing so is likely to break in the future, so force it to break instead.
Sprite IDs are not useful information given they change don't refer to anything outside the loaded game.
Instead, include the filename and nfo line at minimum, and include action A or action 5 sprite replacement information if applicable.
* Fix 2fd90960: Missing default vehicles and industry acceptance/production.
Some default definitions are used across multiple climate types and relied on climate-independent cargo slot even though they specified a climate-dependent cargo type.
Add MixedCargoType that indirectly allows multiple labels to be specified for these.
Town production effect is modelled on town acceptance (growth) effect, and so takes an original cargo slot for behaviour instead of a direct value.
NewGRF feature 0x0B, property 0x1E, takes 1 byte.
Valid values are:
- 0x00 to behave like passengers
- 0x02 to behave like mail
- 0xFF to behave like other cargo (i.e. not produced.)
If not set, town production effect is set based on the cargo label ('PASS' or 'MAIL').
Town production multiplier allows adjusting the amount of cargo produces when Town Production Effect is set, without needing to use callbacks.
NewGRF feature 0x0B (cargo), property 0x1F, accepts a 2 byte (word) value, similar to the cargo capacity multiplier property. The default value is 256 which means 100%, i.e. normal rate.
