7a1faee460 Bail out when the trace advances past the nearest collision. 2011-11-28 20:54:34 +09:00

a943cdf2c4 Handle dual collisions.
When the trace collides with something on both sides of a plane, the nearer
collision is required. The code now correctly checks both sides and keeps
the nearer collision.

0cf5dec5bb Fix the covered step tests.
However,  there is still a problem with moves where the box is always cut
by the plane: both sides need to be tested (done), but when the first side
checked allows longer motion than the second, but still collides, only the
first side is checked. The shorter motion is required.

8cc320b7ef Move the start point to the near side of the crossed plane.
I'm not sure the end point needs to be moved at all, but I'll leave it
alone for now. I have a couple of failing test cases that seem to be caused
by not handling moves where the box is always cut by the plane.

fa6390a46a Correct the sign for the shift in frac.
However, this is not entirely correct as the new start point when testing
the other side of the plane also needs to be calculated.

b82d9f5894 Another test, another bug.
Fix an incorrect test using offset (forgot to negate).

9984a2e87a Fix some missing usages of offset.
This fixes my one failing box clip test. Now I need to find more broken
cases. At least now, they should be real tests.

03abb3b27d Add support for ellipsoids.
Not that boxes work yet, but the fix is the same.

b4da9241f6 Make a fresh start on box clipping.
I even have a failing test to fix :)

a356ce6572 Assume the trace will be allsolid.
Rather than setting allsolid when the trace fails to leave solid space,
clear it when the trace enters non-solid space. This is necessary because
the trace might visit only one node and thus the failure to leave solid
space will not be detected. This fixes the problem with hipnotic's bobbing
water.

9daa0b7bde Rename the empty and solid flags, and use them correctly.
seen_empty and seen_solid much better reflect their meanings, and also use
them correctly (eg, visiting an empty node does not clear seen_solid).
Hipnotic's bobbing water is still broken, though.

981622f969 Make MOD_TraceLine behave "correctly".
MOD_TraceLine now behaves the same as id's SV_RecursiveHullCheck (from
WinQuake). This means that even if the trace would escape from solid space
into non-solid space, the trace is treated as allsolid if it crosses from
one solid space to another before hitting the empty space.

trace-id.c is used only for establishing the behaviour of id's code.

c2af7896bd Revert "make droptofloor continue the trace if it starts solid"
This reverts commit 10232acdfe.

The problem was really in the trace code, but it got fixed by "accident"
when I had similar problems in hipnotic a couple of years later. Now to
figure out just what the trace could really should be doing.

31640dd1b9 Clean out the last traces of my boxclip code.
I've been experiencing funny trace issues while playing Soul of Evil. While
I think the boxclip dregs shouldn't be causing problems, it's probably best
to clean them out properly before trying to fix anything.

8831a109a4 Create and use mclipnode_t.
I didn't realize this was a critical part of fitzquake's large map
support. This should fix the non-solid brush entities in Conflagrant
Rodent.

8c4fe2f844 Rename Sys_DPrintf to Sys_MaskPrintf.
We now have finer runtime control over what gets printed. Need to do a
SYS_DEV audit, creating new masks as apropriate.

2185a3dcd0 Remove almost all of my boxclip developement.
This is to prevent others accidently getting headaches from my code.

51932ee433 --enable-boxclip configure option and some more tweaks, I guess (been too long) 2009-12-19 04:45:01 +00:00

a26cd68ea9 more tests, more progress. just need to fix a regression that popped up while fixing the new test (18) 2009-03-22 00:31:44 +00:00

384ad30df8 correct the last 4 edges. all existing testcases now pass. 2009-03-20 11:38:04 +00:00

fea4189150 complete rewrite of validate_solid. also, put the trace points on the other side of the split plane. Just one more set of related tests to fix. 2009-03-20 11:20:59 +00:00

0ff4165149 why didn't I do this earlier? 2009-03-20 03:40:30 +00:00

f59f2dc7b9 some more progress with box clipping and much a saner test harness 2009-03-20 03:33:03 +00:00

e992edaf31 that fixed the test case (why isn't sgn a standard function? :P) 2009-03-19 04:56:44 +00:00

3be88c3e1d still disabled since it's still broken, but progress has been made. Fortunately, some of the breakage shows up as a regression in the testcases. 2009-03-19 03:16:24 +00:00

d66934942d nuke Con_Printf and Con_DPrintf and use Sys_* instead 2007-11-06 10:17:14 +00:00

e15fae264a well, it finally seems to work, but q1 maps (especially start's ramp to e3) are not such that they're particulary playable due to being designed for point clipping. so still disabled until something can be sorted out. 2007-09-29 23:28:41 +00:00

0ee9e1cf3e more accurate expects and don't recurse for non-crossings 2007-09-23 08:33:26 +00:00

36f5edb9d3 still disabled, but it's mostly working now. serves me right for blindly following the q2 code :P (it be buggy) 2007-09-21 13:58:07 +00:00

b963665ad7 don't stop a trace on transition from solid to non-solid. this fixes the grapple problem in prozaccoop, but really the bug is in the progs but this is a faster fix for now until I decide whether I want to stop a trace on transition or not, or whether to make it optional. 2007-04-28 02:16:47 +00:00

447a3e8254 fix some nasty catches I was experiencing. I don't know why my logic didn't work, but it definitely didn't. 2007-04-07 06:51:36 +00:00

99c0954b47 the big dso visibility patch :). Sure, we have to have unique names for static builds, but with controlled visibitly we should get faster program loads (although this isn't C++, so it's not as bad) and complex plugins are cleaner. 2007-03-10 12:00:59 +00:00

3fb03fc2be hah, should have been using __attribute__((used)) all that time (rather
than __attribute__((unused))). fixes the missing console in -x11

2cb81b37f9 move the *_RecursiveHullCheck functions from pmovetst.c and world.c to MOD_TraceLine in libs/models/trace.c, at the same time rewriting the code to work itteratively rather than recursively.
This is an imperfect revision of history.
