it’s actually a 32 bit integer, if you read it as char then the color order are reversed (because of little endian) and RGBA is an invalid format in most graphics libraries but ARGB is supporteprobably the most supported at the moment. So 0×8000FF00 would be a 50% transparent green but you would find as x00 xFF x00 x80 in the file, if I’m not wrong

I want to thank you for all this information you provided here, it’s helping me a lot on my project and probably will help me more later. Maybe I can help you later to upgrade your editor, as I have some experience on graphics programming (and since two days ago, experience on RO files too).

Regards.

VictorSan, Ximosoft:

The value is most likely ARGB. Alpha comes first in almost every programming language.

Hello,

36 ?? 4 bytes Integer ??

-> I think that this field is really a 4 unsigned char field.

If it´s taken as an integer, it´s usually a big number… i splited it into 4 unsigned chars. The result is 255 255 255 255, it repeats in every tile. I think it´s a RGBA value for that tile.

The same strange value appears in the cubes, in the “tile” fields… i don´t know it it´s the same.

Ximosoft give me credit or i kill you :D .

Yes, texture coordinates are following standard texturing techniques, so 1.0 it’s end (max size) and 0 the start, you can also make mirroring by flipping this values.

Hi,
I think Texture Start and End in a Tile section corresponds to the 2D coordinates of the texture to be applied.

for example, if the texture is 256×256,
0.5 0.75 0.5 0.75 1.0 1.0 0.75 0.75 would be a square in the texture defined by :
(128,255)-> (192,255)->(192,192)->(128,192)

Am I right ?
