Using the chunked data format may provide advantages in drawing speed. The chunked data format is designed to compress tiles and diagonal views of vehicles things with lots of transparency around the edges, and a contiguous block of non-transparent pixels in the middle. Sprite is in chunked data format (aka "tile compression") Currently, the following bits are supported:Ĭolour index 0 is transparent (should be always set ignored if bit 3 is set) Unlike the other numbers, this is a hexadecimal byte.

The best way to circumvent this bug is to upgrade to the newest version. There is a bug in grfcodec 0.9.7 and earlier that prevents them from properly encoding a sprite with a smaller ypos value than any earlier sprite. These are pretty easy to set, as long as you remember that the order is X, Y, Y, X, and not X, Y, X, Y.Īlso, no sprite may contain zero pixels ysize and xsize must both be at least 1. m4 files, or been set by function setpath(). The path should be a relative path, resp omitted at all, and instead be given byĪn external variable in one of your local. Inclusion of the file name in every sprite() function allows to have them This specifies the name of the graphics file containing the sprites.
