A data structure to store information on individual shocks, stored in
Shocks.shocks. Should not be instantiated directly; use
Shocks.register() instead. The properties of this object correspond to arguments of that function.
Click a method name for more detailed documentation.
do( model )
Execute a shock upon the model. Should not be called directly; this function is called in the course of the model step function.
name — str
The short and unique name of the shock, used throughout the code to refer back to it.
desc — str
A long description to display as a tooltip. Note that tooltips require PMW when using the Tkinter frontend.
param — Param
Paramobject whose value to shock.
paramcan also be set to
None, in which case
valFuncbehaves somewhat differently. See below.
valFunc — func
A function that returns a new value for the parameter.
valFunctakes three arguments: the name of the variable being shocked, the parameter type (
Nonefor global parameters,
'good'for per-breed and per-good parameters, respectively), and (for per-breed or per-good parameters) the breed or the good in question. If
valFunctakes one argument, the model object. This can be useful for more complex shocks that do not correspond to a particular parameter.
timerFunc — func(int)|str
A function that takes the current model time and returns a bool, indicating whether to run
valFuncthat period or not.
timerFunccan also be set to the string
'button', in which case a button will be drawn in the control panel that runs
valFuncwhen the button is pressed.
item — str
Specifies the breed or the good whose parameter ought to be shocked if the parameter is a per-breed or per-good parameter.
active — bool
Whether the shock is currently active, i.e. the state of the checkbox in the control panel.
