Dynamic lights flicker after moving them with TeleportGroup

Post by Kraja »

Just as the title says - i'm trying to move 6 Dynamic light sources with TeleportGroup(), but after doing so they start flickering like crazy.



I've had this happen to me on my previous map too, but lights there were flickering seemingly at random. This time however it happens every time.
Does anyone know how to solve this issue?

That's the thing - they're normal point lights.
Grant it - i just figured out a workaround with Thing_Activate and Thing_Deactivate, but still - that's a weird little bug right there.

Dynamic lights can not link themselves into the light lists properly when being teleported. Deactivating and reactivating them is really the only option you have. Glad you found it. ;)

That said, the entire implementation is due for a rewrite from the ground up. The current system with lights being actors is just too troublesome. (It's only being kept because it works and the rewite would be quite invasive.) If the lights were just attachments to some inert actors the problem would mostly go away immediately.
