When opening a world file with the command stage worlds/fasr.world I ran into the following error
Stage 3.1.0
[Loading worlds/fasr.world][Include pioneer.inc][Include map.inc][Include sick.inc]Segmentation fault

A more elaborate error description:
Stage 3.1.0

Continuing.

My OpenGL may be the cause of this, because if I open a world file through the GUI it works fine but does not go to the background if I select another window. Also, I have to pause and unpause before display starts. The model is running before I do that, but it just does not show anything on the screen unless I touch a button.

Discussion

  • I've changed the laser code in a way that *should* fix this, if I understand the problem correctly. I can't reproduce the effect myself, so I'll leave the bug open until I hear what happens.

    If we havent heard back by now I dont think we will. Closing as it should be fixed
