Dead body seems to block line on fire. RC6, winXP, see screenshoots (from mine01n):

Does it on 2.1, latest build also.

Thanks for discovering this.

The client-side tracing code is slightly incorrect - it doesn't do collision with "entities" (like soldiers/aliens) correctly. You will find that even though the interface is indicating the line of fire is blocked, you can still shoot past the dead alien, because the server-side code which controls the actual executed action of shooting does have correct code :-)

There is a simple hack that will fix this, but to do it properly requires fixing the client-side tracing code to bring it in-line with the server's tracing code (indeed the only difference is the way it handles entity collision). I looked at this not so long ago and I do think it is possible, but involves a little work and testing since the client-side and server-side entity model data structures are a bit different (or maybe I missed something obvious). I'll look into implementing a proper fix...

Well I had a look at the client-side tracing code again, but I still can't work out how to trace against the client-side actor models.

So for now I've implemented the simple hack I alluded to earlier (see trunk revision 4920). Testing incidcates this hack performs very well (at least as well as other client-side approximates already in place).

I think the simple approach will suffice for now, however I have added a TODO to the code with some pointers on how the client-side code should ultimately be fixed.

The problem still persists. Bodies do not block the line of fire, but fire always ends at dead body.
