Over time, several features have been added to TTDPatch and OpenTTD that require new sprites. As these sprites are not present in the original base graphics, they cannot be replaced using a normal replace block. Instead, a replacenew block has to be used. The semantics are like this:
replacenew(<type>, <image-file>[, <offset>]) {
list of realsprites
}
The <type> parameter indicates the type of sprites that will be replaced. It should be an identifier from the first column of the following table.
| Type | Number of sprites |
|---|---|
| PRE_SIGNAL | 48 |
| PRE_SIGNAL_SEMAPHORE | 112 |
| PRE_SIGNAL_SEMAPHORE_PBS | 240 |
| CATENARY | 48 |
| FOUNDATIONS_SLOPES | 74 |
| FOUNDATIONS_SLOPES_HALFTILES | 90 |
| TTDP_GUI_25 | 73 |
| TTDP_GUI | 93 |
| CANALS | 65 |
| ONE_WAY_ROAD | 6 |
| COLOURMAP_2CC | 256 |
| TRAMWAY | 113 |
| SNOWY_TEMPERATE_TREES | 133 |
| COAST_TILES | 16 |
| COAST_TILES_BASEGFX | 10 |
| COAST_TILES_DIAGONAL | 18 |
| NEW_SIGNALS | any (a) |
| SLOPED_RAILS | 12 |
| AIRPORTS | 15 |
| ROAD_STOPS | 8 |
| AQUEDUCTS | 8 |
| AUTORAIL | 55 |
| FLAGS | 36 (b) |
| OTTD_GUI | 160 (b) |
| AIRPORT_PREVIEW | 9 (b) |
(a) Any number of sprites is allowed here, however both OpenTTD and NML don't (yet) support the other features required to use these sprites.
(b) Any number of sprites can be specified up to the stated maximum. Furthermore the offset variable can be used, see below for more info.
The amount of sprites has to be equal to the number given in the table, except in the cases of (a) and (b). Having less sprites results in an error. Having more sprites is allowed to provide future compatibility, but a warning will be issued.
Parameter two <image-file> is a literal (quoted) string that specifies the file where the sprites are located.
Parameter <offset> is optional and has a default value of 0. Values greater than zero are only allowed in the case of the sprite types marked with (b). Setting this value sets an offset into the block of sprites, so only a subset of the sprites (starting at offset) will be replaced.
