Use Inkscape.

WolfHaley: Gimp is a tool to make maps like Red vs Blue or Winter Shoppa. To make those map, choose any pictures you find on your pc or internet.
Make a transparent layer, then drag some/a picture to Gimp then delete the part you don't want to use. Then repeat the previous step as much as you want. Lastly, save the file as PNG tpye.

Forty-Two: :O , can you teach me how to use it?

I used Inkscape for Cowrace and the Wooden Fort, its really best for making HW-Maps, youll see!

TEACH ME!

Mystery+anyone else interested: There are several tutorials on the Inkscape site that are useful http://inkscape.org/. But I've found the best way (for me at least :l) to learn is to mess around in Inkscape and see what you get.

I searched for some tutorial but it seems useless to me. Star, can you tell me which part of tutorial did you understand and can be use (if you remembered) to makes Shoppa Maps?

well i guess you already saw my video for inkscape
what you don't know to do a shoppa map ? just draw something....

( in case you never see my video http://www.youtube.com/watch?v=ZwYrG-qqv2M , if you don't understand something, say what )

I watched your video and i have one question ; how to put the texture?

good question :

for example : if you want the hell texture, or a hedgewars texture...
find it in Hedgewars 0.9.17\share\hedgewars\Data\Themes\Hell the file is : landtex (choose the one you want )
then copy it to your inkscape file (the same as the map)
select the new object you want for texture ; use alt+i
in french its : objet--motif--objet en motif / that mean something like : use it as pattern

then select your map, a rectangle, 2 circle or what you want to be textured :
shift+ctrl+F (objet--remplissage et contour) ( objet is the 5th column)
then i don't know the word to explain....

in french i would say : tu as l'onglet : fond, tu peux choisir comment tu le remplis, choisis : motif, ensuite selectionne le motif que tu veux, celui que tu viens de copier)

if i can modify my video i'll do it

here is the video for mystery https://www.youtube.com/watch?v=GXSMekhZ-vs

go to 2.51

it should be more easy to understand now

Thanks :'P

lolkiller has recommended me Gimp, i tried Inkscape but i just can`t add the texture, when i do, i save the file but then when i try it on game the texture is gone how can i do? also i would like to know how to make a map adding any picture you find, could you explain clem? im a bit lost :s

hum, could you screencast how you do when you apply your texture, and when you save it
or screenshot it (to see where you click etc...)

(add a picture, don't see the problem
en francais : clique et glisse l'image vers ton fichier inkscape ouvert...)

for gimp question, ask lollkiller

Its very simple to make your own map. (use Gimp, Inkscape, Photoshop, paint or whatever program you like)

Guide on the easiest way to make a map.
1. download any mappack from the dlc (you can also skip this part and go to 2b)
2a. go to the folder:
-------
My Documents/Hedgewars/Data/Maps (Windows)
~/.hedgewars/Data/Maps (Linux)
~/Library/Application Support/Hedgewars/Data/Maps (OSX/Mac)
-------
If it does not exist then read 2b.
2b. go to the place where all your game content was installed and navigate to ./Data/Maps
3. Copy any any of the folders and rename it to the name of your map.
4. Open map.png (inside the folder you copied) and figure out how it was made, then erase it (using the erasing tool) and start draw your own.
5. Start hedgewars and try it out!

It's totally really very too impossible to use paint for drawing maps
