Module mopp

Get path to the mopper.

>>> path = getMopperPath()
>>> path.endswith("mopper.exe")
True

Returns: str

Path to mopper.exe.

Raises:

• OSError - If mopper.exe is not found.

Get info about mopper, and credit havok.

>>> print(getMopperCredits())

Returns: str

Credits string.

Raises:

• OSError - If mopper.exe is not found or cannot run.

Generate mopp code and welding info for given geometry. Raises RuntimeError if something goes wrong (e.g. if mopp generator fails, or if mopper.exe cannot be run on the current platform).

Call L{getMopperCredits} before calling this function if you need to credit havok in a console application that uses this function.

For example, creating a mopp for the standard cube:

>>> expected_moppcode = [
...     40, 0, 255, 39, 0, 255, 38, 0, 255, 19, 129, 125, 41, 22, 130,
...     125, 12, 24, 130, 125, 4, 38, 0, 5, 51, 39, 0, 5, 50, 24, 130,

...     249, 255, 48]
>>> orig, scale, moppcode, welding_info = getMopperOriginScaleCodeWelding(

Parameters:

• vertices (list of tuples of floats) - List of vertices.
• triangles (list of tuples of ints) - List of triangles (indices referring back to vertex list).
• material_indices (list of ints) - List of material indices (optional).

Returns: tuple of floats, float, list of ints, and list of ints

The origin as a tuple of floats, the mopp scale as a float, the mopp code as a list of ints, and the welding info as a list of ints.

Raises:

• RuntimeError - If the mopper has bad output.
• OSError - If the mopper is not found or cannot run.
