Spring RTS Engine

Hi,

I have problem with a map:

When i compiled my map with a PNG texture with alpha canal, I obtain map with correctly texture, but the minimap in spring is bugged (black with big pixel of random color).

When i compiled with a 24bip BMP image, i have logically a non-transparency texture, but i have minimap.

And when i try to compile map with a 32 bit BMP image, mapconv (i test with different version of mapconv) don't compile it with an error with a format of texture map.

How i have a transparence in texture with fonctionnal minimap?

Not canal... A canal is a waterway.

You mean a Channel (which an alternate meaning is a waterway, but whatever...).

Um without addressing your issues directly, do this...

Resize your diffuse texture to 1024x1024, save as minimap.bmp, include in map archive. Problem solved (sort of).

Sorry, yes alpha channel!

For the minimap.bmp on 1024*1024 , i have put it in archive (in the subdirectory maps/) but it doesn't solve problem

Are you using smd or mapinfo.lua?

If you're using mapinfo.lua, you have to tell the filename of the minimap to mapinfo.lua (it's one of the parameters iirc).

Nevermind, no it isn't a param, arugh, I can't remember how to do custom minimaps. Iirc you simply had to include minimap.bmp in the archive. Perhaps I was wrong.

it *should* be one of the paremeters though,, the smf format is stupid, maybe someone will get around to turning all smf sections into mapinfo.lua ones.. someday..

Hi,

I use mapinfo.lua, and i haven't found param to solve problem. in the mapinfo.lua, we can precise the smf file but no minimap.

I see somethings, we can with "voidground" param in mapinfo that there is possible to have invisible portion of texture, if the map was compiled with a diffuse map with an alpha channel. Although, it'ss the same problem, mapconv don't compile with a 32bit BMP image for texture.

The minimap is a 1024x1024 DXT1 compressed image inside the smf file

In compilation, i have an error about minimap:
"error reading mini.bmp", it's strange because, it create itself this file and after it don't read it?

I use mapconvGUI 2.4 without special option

Rename your minimap that you created to mini.bmp and place it in the same folder as mapconv and recompile.

To exclude problem sources: you don't happen to use mapconv under linux with wine?
Just asking since I always get this error when trying to do it this way. Under windows it worked fine (also with transparent textures); no matter if minimap is automatically produced or a png is supplied. But I never tried mapconvGUI, just the command line version of 2.4.

Alpha in minimap is not supported. I've been trawling through the map code this afternoon.

I dont know anything much about opengl so dont know how to enable it.. probably not worth it though.

I meant of course transparency in the diffuse texture, not minimap. Sorry for not being more precise before.
Transparent minimap doesn't make much sense, IMO.

oh I misunderstood..

if you want you can try my compiler.
smf_tools. you will have to build for windows using msys2+mingw

ive submitted a patch to allow specifying the minimap from the mapinfo.lua file too, so if that goes through then its a moot point.
