CLI tool for converting Tiled TMX files to Panda3D BAM files.

Usage:

$ pip install panda3d-tmx2bam
$ tmx2bam path/to/tmx/file.tmx path/to/bam/file.bam -prefabs=path/to/prefabs.bam

or

from tmx2bam import Tmx2Bam
from direct.showbase.ShowBase import ShowBase

base = ShowBase()
tmx_map = Tmx2Bam("path/to/tmx/file.tmx", prefabs="path/to/prefabs.bam")
tmx_map.node.reparent_to(render)
base.run()

Prefabs are optional. Without them all tiles will be cards. Find important tiles and their properties like so:

tiles_with_my_property = tmx_map.node.find_all_matches('**/=my_property_name')
for tile in tiles_with_my_property:
  my_property_value = tile.get_tag("my_property_name")

Currently supports:

• TMX file with CSV data (default)
• Custom properties as PandaNode tags
• Multiple tilesheets
• Multiple layers and Groups
• Animated tiles
• Object layer/Objects (point, poly, rectangle, text, image)
• Background images
• Merge animated sprites
• Allow more shapes than just cards

Left to do:

• Infinite maps (chunks)
• Hexagonal and Isometric tiles
• Tile render order
• Tilesheet image collection
• Embedded tilesheet in tmx
• Embedding texture in bam
• Tiled features I'm not aware of
• Error handling
• A better readme

Exporter specific custom layer properties:

• "flatten" will flatten_strong() the layer
• "store_data" will store the data in the layer with set_python_tag()
• "z" set's the layer's z height.

Prefabs: To use prefabs, simply make a bam (with blender and blend2bam for example), where each root object is a nodepath named after a type in the spritesheet's tsx. Tmx2bam will then replace the tiles or objects that have this type assigned with this nodepath.

Mind:

• The Y axis is inverted in panda3d.
• Animated sprites can only have one steady frame-rate that you can set on the first frame in Tiled.
• Currently the image resolutions have to be power of two.
• Rendering tons of individual tiles is slow. Use the "flatten" property as much as possible.
• The ellipse and point objects are not drawn at this time, they're empty nodepaths.
• I'm not a programmer but I play one on TV. Your mileage may vary.

Fun snippets:

• Adding a "repeat" property to a "cube" prefabed tile to make towers and large walls and things.

for layer in tmx2bam.node.find_all_matches("**/=repeat"):
    repetitions = layer.get_tag("repeat")
    repeats_node = NodePath(layer.name+"-repeat")
    for repetition in range(int(repetitions)):
        repeat = NodePath("repeat")
        layer.copy_to(repeat)
        repeat.set_z(layer.get_z()+repetition-1)
        repeat.reparent_to(repeats_node)
    repeats_node.flatten_strong()
    repeats_node.reparent_to(layer)
