A alternative_sprites block allows you to specify alternative sprites (zoom levels and / or 32bpp) that are drop-in replacements for some real sprites in your grf. The syntax is as follows:
alternative_sprites(block_name, zoom_level, type[, filename]) {
list of realsprites
}
block_name is the name of the replace/replace_new/fontglyph/spriteset-block for which you want to provide alternative sprites. zoom_level can be
| name | tile size | description |
|---|---|---|
ZOOM_LEVEL_IN_4X |
256 x 127 | 4x zoom in |
ZOOM_LEVEL_IN_2X |
128 x 63 | 2x zoom in |
ZOOM_LEVEL_NORMAL |
64 x 31 | normal tile size |
ZOOM_LEVEL_OUT_2X |
32 x 15 | 2x zoom out |
ZOOM_LEVEL_OUT_4X |
16 x 7 | 4x zoom out |
ZOOM_LEVEL_OUT_8X |
8 x 3 | 8x zoom out |
The type argument specifies which kind of sprite follows. This may be either BIT_DEPTH_8BPP or BIT_DEPTH_32bpp.
Specifying a filename is optional, it's only useful if you have multiple sprites in the same file. If every sprite is in a separate file you'll have to specify the filename for each realsprite anyway, so you can leave it out of the alternative_sprites-block.
An example for an implementation
// Foster Express tram
spriteset(foster_express_set, "opengfx_generic_trams1.pcx") {
[ 48,56, 8,18, -3,-10]
[ 64,56, 20,19, -14, -5]
[ 96,56, 28,15, -14, -8]
[144,56, 20,19, -6, -7]
[176,56, 8,18, -3,-10]
[192,56, 20,19, -14, -9]
[224,56, 28,15, -14, -8]
[272,56, 20,19, -6, -7]
}
alternative_sprites(foster_express_set, ZOOM_LEVEL_IN_2X, BIT_DEPTH_8BPP, "opengfx_generic_trams1.pcx") {
[ 48,56, 8,18, -3,-10]
[ 64,56, 20,19, -14, -5]
