LParabolaf
from panda3d.core import LParabolaf
- class LParabolaf
Bases:
An abstract mathematical description of a parabola, particularly useful for describing arcs of projectiles.
The parabolic equation, given parametrically here, is P = At^2 + Bt + C.
Inheritance diagram
- __init__()
Constructs a meaningless degenerate parabola.
- __init__(copy: LParabolaf)
- __init__(a: LVecBase3f, b: LVecBase3f, c: LVecBase3f)
Constructs a parabola given the three points of the parametric equation: the acceleration, initial velocity, and start point.
- assign(copy: LParabolaf) LParabolaf
- get_a() LVecBase3f
Returns the first point of the parabola’s parametric equation: the acceleration.
- get_b() LVecBase3f
Returns the second point of the parabola’s parametric equation: the initial velocity.
- get_c() LVecBase3f
Returns the third point of the parabola’s parametric equation: the start point.
- read_datagram(source: DatagramIterator)
Reads the parabola from the Datagram using get_stdfloat().
- read_datagram_fixed(source: DatagramIterator)
Reads the parabola from the Datagram using get_float32() or get_float64(). See
write_datagram_fixed().
- write_datagram(destination: Datagram)
Writes the parabola to the Datagram using add_stdfloat(). This is appropriate when you want to write the vector using the standard width setting, especially when you are writing a bam file.
- write_datagram_fixed(destination: Datagram)
Writes the parabola to the Datagram using add_float32() or add_float64(), depending on the type of floats in the parabola, regardless of the setting of
Datagram.set_stdfloat_double(). This is appropriate when you want to write a fixed-width value to the datagram, especially when you are not writing a bam file.
