Detailed Description

An animation channel that issues a matrix each frame, read from a table such as might have been read from an egg file.

The table actually consists of nine sub-tables, each representing one component of the transform: scale, rotate, translate.

Member Function Documentation

◆ __init__()

__init__ ( AnimGroup  parent,
str  name 
)

◆ clearAllTables()

clearAllTables ( )

Removes all the tables from the channel, and resets it to its initial state.

◆ clearTable()

clearTable ( char  table_id)

Removes the indicated table from the definition.

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getTable()

CPTAStdfloat getTable ( char  table_id)

Returns a pointer to the indicated subtable's data, if it exists, or NULL if it does not.

◆ hasTable()

bool hasTable ( char  table_id)

Returns true if the indicated subtable has been assigned.

◆ isValidId()

static bool isValidId ( char  table_id)
static

Returns true if the given letter is one of the nine valid table id's.

◆ setTable()

setTable ( char  table_id,
const CPTAStdfloat  table 
)

Assigns the indicated table.

table_id is one of 'i', 'j', 'k', for scale, 'a', 'b', 'c' for shear, 'h', 'p', 'r', for rotation, and 'x', 'y', 'z', for translation. The new table must have either zero, one, or get_num_frames() frames.
