## Enumeration Type Documentation

enum ChangeInfoResult

  CIR_SUCCESS | Variable was parsed and read.
  CIR_UNHANDLED | Variable was parsed but unread.
  CIR_UNKNOWN | Variable is unknown.
  CIR_INVALID_ID | Attempt to modify an invalid ID.

## Function Documentation

static void ActivateOldShore | ( |  | ) | `[static]`

Relocates the old shore sprites at new positions.

1. If shore sprites are neither loaded by Action5 nor ActionA, the extra sprites from openttd(w/d).grf are used. (SHORE_REPLACE_ONLY_NEW) 2. If a newgrf replaces some shore sprites by ActionA. The (maybe also replaced) grass tiles are used for corner shores. (SHORE_REPLACE_ACTION_A) 3. If a newgrf replaces shore sprites by Action5 any shore replacement by ActionA has no effect. (SHORE_REPLACE_ACTION_5)

Definition at line 6477 of file newgrf.cpp.

References GRFLoadedFeatures::shore, SHORE_REPLACE_ACTION_5, SHORE_REPLACE_ACTION_A, and SHORE_REPLACE_NONE.

static void ConvertTTDBasePrice | ( | uint32 | base_pointer,
|  | const char * | error_location,
|  | Price * | index |
| ) |  |  | `[static]`

Converts TTD(P) Base Price pointers into the enum used by OTTD See http://wiki.ttdpatch.net/tiki-index.php?page=BaseCosts.

Parameters:

  | base_pointer | TTD(P) Base Price Pointer
  | error_location | Function name for grf error messages
  | index | If base_pointer is valid, index is assigned to the matching price; else it is left unchanged

< Position of first base price

< Size of each base price record

static void DisableStaticNewGRFInfluencingNonStaticNewGRFs | ( | GRFConfig * | c | ) | `[static]`

Disable a static NewGRF when it is influencing another (non-static) NewGRF as this could cause desyncs.

We could just tell the NewGRF querying that the file doesn't exist, but that might give unwanted results. Disabling the NewGRF gives the best result as no NewGRF author can complain about that.

Parameters:

  | c | the NewGRF to disable.

static void FinaliseHouseArray | ( |  | ) | `[static]`

Add all new houses to the house array.

House properties can be set at any time in the GRF file, so we can only add a house spec to the house array after the file has finished loading. We also need to check the dates, due to the TTDPatch behaviour described below that we need to emulate.

static void FinaliseIndustriesArray | ( |  | ) | `[static]`

Add all new industries to the industry array.

Industry properties can be set at any time in the GRF file, so we can only add a industry spec to the industry array after the file has finished loading.

bool GetGlobalVariable | ( | byte | param,
|  | uint32 * | value |
| ) |  |  |

Reads a variable common to VarAction2 and Action7/9/D.

Returns VarAction2 variable 'param' resp. Action7/9/D variable '0x80 + param'. If a variable is not accessible from all four actions, it is handled in the action specific functions.

Parameters:

  | param | variable number (as for VarAction2, for Action7/9/D you have to subtract 0x80 first).
  | value | returns the value of the variable.

Returns:
  true iff the variable is known and the value is returned in 'value'.

Returns the engine associated to a certain internal_id, resp.

allocates it.

Parameters:

  | file | NewGRF that wants to change the engine
  | type | Vehicle type
  | internal_id | Engine ID inside the NewGRF
  | static_access | If the engine is not present, return NULL instead of allocating a new engine. (Used for static Action 0x04)

Returns:

DEBUG() function dedicated to newGRF debugging messages Function is essentialy the same as DEBUG(grf, severity, .

..) with the addition of file:line information when parsing grf files. NOTE: for the above reason(s) grfmsg() should ONLY be used for loading/parsing grf files, not for runtime debug messages as there is no file information available during that time.
