Animation Format

VCMI allows overriding HoMM3 .def files with .json replacement. Compared to .def this format allows:

• Overriding individual frames from json file (e.g. icons)
• Modern graphics formats (targa, png - all formats supported by VCMI image loader)
• Does not requires any special tools - all you need is text editor and images.

Note that right now this replacement is not supported fully: there are still some areas that can't use it. Most notable areas are:

• Adventure map
• Battles

Format description

{
    // Base path of all images in animation. Optional.
    // Can be used to avoid using long path to images 
    "basepath" : "path/to/images/directory/",

    // List of sequiences / groups in animation
    // This will replace original group with specified list of files
    // even if original animation is longer
    "sequences" :
    [
        {
            // Index of group, zero-based
            "group" : 1,

            // List of files in this group
            "frames" :
            [
                "frame1.png",
                "frame2.png"
                    ...
            ]
        },
        ...
    ],

    // Allow overriding individual frames in file
    "images" :
    [
        {
            // Group of this image. Optional, default = 0
            "group" : 0,

            // Imdex of the image in group
            "frame" : 0,

            // Filename for this frame
            "file" : "filename.png"
        }.
        ...
