Spring RTS Engine

For some reason, projectiles are globally visible. I'd like to propose to make them only visible when player has LOS, because, that's how we define line of sight. How come you can see the debris from a shell outside of LOS, but not a hawk fighter?

At least make it possible for game developers to choose how the visibility behaves.

Also, as a condequence, accessing projectiles withing LOS should be possible from a widget, just like it is currently possible with units.

There's a very high likelyhood this change would slow the engine to a crawl - even if limited to long-range weapons. LOS checking is expensive.

Then is there a way to make LOS checking less expensive? Many other games have it. It's a fundament to a rts game.

check the wiki ...

Care to be a bit more specific?

he is probably talking about
AlwaysVisible =0

which at the very least does not apply to missiles, I just checked in game.
