As each `type` has a well defined length, you can read the records even without knowing anything about the chunk-tag yourself. Do remember, that if the `type` had the `0x10` flag active, the field in the record first has a `gamma` to indicate how many times that `type` is repeated. + +#### Guidelines for network-compatible patch-packs + +For network-compatible patch-packs (client-side patches that can play together with unpatched clients) we advise to prefix the field-name with `__<shortname>` when introducing new fields to an existing chunk. + +Example: you have an extra setting called `auto_destroy_rivers` you want to store in the savegame for your patched client called `mypp`. +We advise you to call this setting `__mypp_auto_destroy_rivers` in the settings chunk. + +Doing it this way ensures that a savegame created by these patch-packs can still safely be loaded by unpatched clients. +They will simply ignore the field and continue loading the savegame as usual. +The prefix is strongly advised to avoid conflicts with future-settings in an unpatched client or conflicts with other patch-packs. |
