This module contains the core part of the sprinbots, which is their
nodes and springs. Here are implemented all the physics behaviour and
interations among those parts.
|
|
ANGLE_STEP = 0.025
The rate which the angle changes, this parameter affects the
frequency of motion of springs
|
|
|
GRAVITY = (0, 0.3)
Acceleration vector aplied every step of simulation on nodes
|
|
|
AIR_RESISTANCE = 0.01
% of node's velocity lost every step of simulation
|
|
|
ELASTICITY = 0.6
Parameter which determines the force of springs
|
|
|
VISCOSITY = 0.05
Causes buoyancy force on springs motion
|
|
|
NODE_WEIGHT = 1.26
This parameter is not used on physics
|
|
|
RADIUS = 8
Node's radius
|
|
|
MAX_NORMAL = 400.0
Maximum spring's normal
|
|
|
UP = 1
Direction constant: UP
|
|
|
DOWN = 2
Direction constant: DOWN
|
|
|
LEFT = 3
Direction constant: LEFT
|
|
|
RIGHT = 4
Direction constant: RIGHT
