GMB_TRAIN_WIDTH_32_PIXELS | Use 32 pixels per train vehicle in depot gui and vehicle details. Never set in the global variable;.

bool GetGlobalVariable | ( | uint8_t | param, |
uint32_t * | value, | ||
const GRFFile * | grffile | ||
) |
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.
param | variable number (as for VarAction2, for Action7/9/D you have to subtract 0x80 first). |
value | returns the value of the variable. |
grffile | NewGRF querying the variable |

void GrfMsgI | ( | int | severity, |

Debug() function dedicated to newGRF debugging messages Function is essentially 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.
severity | debugging severity level, see debug.h |
msg | the message |

void LoadNewGRF | ( | SpriteID | load_index, |

void ReloadNewGRFData | ( | ) |
Reload all NewGRF files during a running game.
This is a cut-down version of AfterLoadGame(). XXX - We need to reset the vehicle position hash because with a non-empty hash AfterLoadVehicles() will loop infinitely. We need AfterLoadVehicles() to recalculate vehicle data as some NewGRF vehicle sets could have been removed or added and changed statistics
