Hello,
My model is a car. I will control it to run through a maze (not always straight). I defined an initial variable — distance=0. And I want to know how to record the distance it move from the initial position to the end. Thank you for spending your time on answering my question.

You can accumulate traveled distance (distance d between current position and previous position) in a child script like so:

Code: Select all

function sysCall_init()
    self=sim.getObjectHandle('.')
    distance=0
    lastPosition=sim.getObjectPosition(self,-1)
end

function sysCall_sensing()
    local p=sim.getObjectPosition(self,-1)
    local d=0; for i=1,3 do d=d+math.pow(p[i]-lastPosition[i],2) end; d=math.sqrt(d)
    lastPosition=p
    distance=distance+d
end

Thank you so much, fferi!
