bool Convert8bitBooleanCallback | ( | const GRFFile * | grffile, |
uint16_t | cbid, | ||
uint16_t | cb_res | ||
) |
Converts a callback result into a boolean.
For grf version < 8 the first 8 bit of the result are checked for zero or non-zero. For grf version >= 8 the callback result must be 0 or 1.
grffile | NewGRF returning the value. |
cbid | Callback returning the value. |
cb_res | Callback result. |
Definition at line 554 of file newgrf_commons.cpp.
bool ConvertBooleanCallback | ( | const GRFFile * | grffile, |
uint16_t | cbid, | ||
uint16_t | cb_res | ||
) |
Converts a callback result into a boolean.
For grf version < 8 the result is checked for zero or non-zero. For grf version >= 8 the callback result must be 0 or 1.
grffile | NewGRF returning the value. |
cbid | Callback returning the value. |
cb_res | Callback result. |

void ErrorUnknownCallbackResult | ( | uint32_t | grfid, |
uint16_t | cbid, | ||
uint16_t | cb_res | ||
) |
Record that a NewGRF returned an unknown/invalid callback result.
Also show an error to the user.
grfid | ID of the NewGRF causing the problem. |
cbid | Callback causing the problem. |
cb_res | Invalid result returned by the callback. |
Definition at line 505 of file newgrf_commons.cpp.
Returns company information like in vehicle var 43 or station var 43.
owner | Owner of the object. |
l | Livery of the object; nullptr to use default. |

CommandCost GetErrorMessageFromLocationCallbackResult | ( | uint16_t | cb_res, |
const GRFFile * | grffile, | ||
StringID | default_error | ||

Get the error message from a shape/location/slope check callback result.
cb_res | Callback result to translate. If bit 10 is set this is a standard error message, otherwise a NewGRF provided string. |
grffile | NewGRF to use to resolve a custom error message. |
default_error | Error message to use for the generic error. |
Definition at line 469 of file newgrf_commons.cpp.
Get the tile at the given offset.
parameter | The NewGRF "encoded" offset. |
tile | The tile to base the offset from. |
signed_offsets | Whether the offsets are to be interpreted as signed or not. |
axis | Axis of a railways station. |
