Implementation of Action 04 "universal holder" structure and functions.
This file implements a linked-lists of strings, holding everything that the newgrf action 04 will send over to OpenTTD. One of the biggest problems is that Dynamic lang Array uses ISO codes as way to identifying current user lang, while newgrf uses bit shift codes not related to ISO. So equivalence functionnality had to be set.

void StartTextRefStackUsage | ( | const GRFFile * | grffile, |
byte | numEntries, | ||
const uint32 * | values | ||
) |
Start using the TTDP compatible string code parsing.
On start a number of values is copied on the TextRefStack. You can then use GetString() and the normal string drawing functions, and they will use the TextRefStack for NewGRF string codes.
However, when you want to draw a string multiple times using the same stack, you have to call RewindTextRefStack() between draws.
After you are done with drawing, you must disable usage of the TextRefStack by calling StopTextRefStackUsage(), so NewGRF string codes operate on the normal string parameters again.
grffile | the NewGRF providing the stack data |
numEntries | number of entries to copy from the registers |
values | values to copy onto the stack; if NULL the temporary NewGRF registers will be used instead |
