ScriptController [SCONE]

Controller defined through a Lua script.

Runs the script defined in the file defined by script_file, which is relative to the folder of the scone scenario:

ScriptController {
    script_file = "data/script_file.lua"
    external_files = [ "data/my_included_file.lua" ]
}

Example of a Lua controller script:

function init( model, par, side )
    -- This function is called at the start of the simulation
    -- 'model' can be used to initialize the desired actuators (see LuaModel)
    -- 'par' can be used to define parameters for optimization (see LuaPar)
    -- 'side' denotes if the controller is for a specific side (-1 = left, 0 = unspecified, 1 = right)
end

function update( model, time, controller )
    -- This function is called at each simulation timestep
    -- Use it to update the actuator inputs
    -- 'model' can be used to update the desired actuators (see LuaModel)
    -- 'time' is the time elapsed since this controller was activated
    -- 'controller' can be used to enable/disable child controllers of this ScriptController (see LuaController)
    return false -- change to 'return true' to terminate the simulation early
end

function store_data( current_frame )
    -- This function is called at each simulation timestep
    -- 'current_frame' can be used to store values for analysis (see LuaFrame)
end

Parameter	Type	Description
script_file	path	filename of the Lua script, path is relative to the .scone file
external_files	ArrayOfFiles	Array of files used by the Lua script; files included by 'require' should be added here as `external_files = [ file1, file2 ]`.
name	String	Name of the controller, uses as a prefix for the control parameters; empty by default.
start_time	TimeInSeconds	Time [s] at which Controller becomes active; default = 0.
stop_time	TimeInSeconds	Time [s] at which Controller becomes inactive; default = until simulation ends.
signature_prefix	String	Prefix signature with custom string. Special tags: DATE_TIME, DATE_TIME_EXACT, SCONE_VERSION.
signature_postfix	String	Append custom string to signature. Special tags: DATE_TIME, DATE_TIME_EXACT, SCONE_VERSION.
signature	String	Set custom signature and omit the auto-generated signature.
