Hello,
I have a question about restarting the simulation from a component’s script.
In my application, I use a component’s behavior to detect when a specified simulation duration is reached. When this happens, I want to restart the simulation from the component’s script.
I tried doing this with the code below.
The simulation restarts, but it seems that the component behavior I used to restart the simulation is not running in the new simulation.
By tracing the execution, it appears that the script gets stuck at the instruction directly after app.startSimulation() (in my case, it gets stuck at the beginning of the while loop).
Do you have any idea what might be causing this issue?
Thank you.
