^{[[en:bert|<- main page]]} ====== Textures ====== It is relative easy to edit or create new textures. All textures are located in the subdirectory //textures/// and do have a size of 64x64 pixel. __Note__: If you edit your textures with [[http://gimp.org|The Gimp]], you should activate the grid (//View -> [x] Show Grid//). Then, you configure its appearance with //Image -> Configure Grid//. Width and height should be set to 64 pixel and the color to yellow or some other flashy color. For the line style you should use //dashed//. Now it is very easy to get a clue about the texture size. ===== Terrain ===== {{ bert:editing:tex_grass_borders.png}}{{ bert:editing:tex_grass.png}} The name of terrain textures should start with //tex_//. The width is 64 pixel and the height a multiple of 64. Thus, one terrain type can have several litte varying textures, which get randomly chosen on mapload. To let the game know about your textures, you need the file //tex_list.txt// located under the directory //textures//. On each line, you write a single character, followed by a space, followed by a filename. Thus, each character gets associated with a texture (take a look at [[maps]] for further instructions on how to use these textures in your map). example: g tex_grass.png d tex_desert.png p tex_path.png F tex_forest.png - tex_fence_h.png | tex_fence_v.png ===== Improvements ===== {{ :bert:editing:imp_grass.gif|imp_grass.gif}} {{ :bert:editing:imp_grass.png|imp_grass.png}} These so called "improvements" are additional (animated), randomly placed textures to let the environment look more realistic. Their names should start with //imp_//. Because of the animation we need four 64 pixel sized frames, thus their width is 256 pixel (4*64). The height is similar to our terrain textures a multiple of 64, letting the game randomly select between them. You have to declare them in the file //imp_list.txt// similar to terrain textures: g imp_grass.png F imp_forest.png Terrain textures described by the character //g// do have their improvements in the file //imp_grass.png//. ===== Transparency ===== All textures may have transparent areas, but you shouldn't use them on terrain textures. For transparency you can use the file format [[wp>PNG|Portable_Network_Graphics]], which supports real transparency. Or you draw with the color pink ([[wp>RGB_color_model|RGB]]: 255, 0, 255; [[wp>Hex_triplet#Hex_triplet|hex triplet]]: FF00FF), which gets removed by the game. ^{[[en:bert|<- main page]]}
