Subject: NetAnim Not Showing Packet Animations Despite Enabling Route Tracking in TDMA Simulation

[Pratyush Sharma]

Hi everyone,

I'm working on a custom TDMA-based duplex communication simulation in ns-3 (version 3.42) using WiFi, and I’ve enabled NetAnim visualization successfully. I can see all nodes (UEs and base station) positioned correctly, and the simulation runs without errors.

However, the issue is that no packet animations appear in NetAnim — I only see the nodes.

Hi,

thanks for reporting this. We're aware that NetAnim is in dire need of some bugfixes, but currently we lack a maintainer expert on QT (any help is appreciated).

I got reports that older NetAnim versions might be working, so my best advice is to try an older version.

There was a recent bugfix commit to fix wireless animations, so I
recommend instead to try the latest development version of NetAnim, or
at least make the below change in your NetAnim code and rebuild it:
