Callbacks (12)

For ships, the following callbacks have to be enabled by setting the corresponding bit in property 12 (certain other, not as frequently used callbacks are available without setting a bit here):

||Bit|Value|Variable 0C value|Callback

2|4|12|Load amount

3|8|15|Set refitted capacity

5|20|19|show a suffix after the cargo type name

6|40|2D|Select color mapping for vehicle

7|80|33|Sound effect callbacks||

Bit is the bit you have to set, you do this by adding all the values for all the bits. Variable 0C value is what variable 0C will be set to, for checking it in the variational action 2 for callbacks.

Miscellaneous flags (17)

This is a bit mask, with the following bits:

||Bit|Value|Meaning

0|1|reserved, do not use

1|2|Uses two company colors||

Long format introduction date (1A)

Set the vehicle introduction date, in days since the year 0. This takes account of leap years; dividable by 4, but not 100 unless 400. A start date of 1920-01-01 is obtained with a value of 701265 (51 B3 0A 00). This property must be set after property 00 to take effect. In TTDPatch, dates after 2044 will be limited to 2044.

Sort vehicle list (1B)
