A very powerful tool to customise your simulation. Write your own functions to modify the inputs
into the simulation.
Example 1: simple kJ-limited boost
kj = kj or 25
if speedMs < airSpeedMs
and kj > 0 then
boost = power * 0.2
power = power + boost
boostKj = boost * stepS / 1000
kj = kj - boostKj
end
Example 2: overwrite simulation inputs
cda = 0.4
massKg = 95

Tips
-
Use globals for memory, e.g.
kj = kj or 25.
-
Avoid infinite loops (like
while true do ... end) – they are blocked.
-
Keep logic light – your script runs thousands of times per ride.
