HTTP client code now tracks the reason for failure better (so we can distinguish between dns, no response, disconnects, and tls cert issues). Downloads menu shows reasons for failure for its various sources. make hexen2's +infoplaque button work even when tab isn't held! Yes! usability! who'd a thought it? Try to clean up some client-only build issues. Added 'librequake' as a recognised game name (mostly so that we can reuse the quake-specific engine compat settings. .map support now supports patches enough to query+create(+network)+select them. Collisions are basically defective though. qcc: Remove char as default keyword. qcc: Fix some recent regressions. sv: Add 'sv_protocol csqc' setting to force csqc protocols on clients that disabled handshakes, for mods that NEED csqc support. other options include 'fte1' and 'fte2', if you want to force extra stuff. Engines that don't support the selected protocols will crash out so only set these if your mod/map always requires it. sv: default to qw physics whenever a mod defines the SV_RunClientCommand, even if its an nq mod. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5775 fc73d0e0-1445-4013-8a0c-d673dee63da5

A quick note on tenebrae and sprites: In tenebrae, sprites are always lit, unless the light_lev field is set (which makes it fullbright).
|
|
While its generally preferable and more consistent to assume lit sprites, this is incompatible with vanilla quake and thus unacceptable to us, but you can set the mod_assumelitsprites cvar if you want it.
|
|
So for better compatibility, we have a whitelist of 'well-known' sprites that tenebrae uses in this way, which we do lighting on.
|
|
You should still be able to use EF_FULLBRIGHT on these, but light_lev is an imprecise setting and will result in issues. Just be specific about fullbright or additive.
|
|
DP on the other hand, supports lit sprites only when the sprite contains a ! in its name. We support that too.
