Instead of using the preprocessor to filter out debugging code, we might
want to make more use of the optimizer's DCE. That way, renaming and
moving a function or variable won't immediately break a rarely tested
configuration.
When OC fails while in startup code, resetting the gamma ramp was trying
to use an uninitialized C4Draw, which would result in writes to invalid
memory.
- Increase light fade-in/fade-out quite a bit (4 times stronger)
- Fixed normal jump when multiple lights intersect (will make things a
little less nice with only one light, but this takes priority)
- Don't draw objects without light in light-debug mode
Printing pointers from the crash handler has been broken starting
with an update to MinGW at some point in the past, when they stopped
using printf from MSVCRT, instead replacing it with a private
implementation. Fix this by checking for inttypes.h availability, and
using it (and its format macro) when possible.
The "b" value returned by the new find_cross function had basically
nothing to do with what the old version did (it was for the other
pair of coordinates *and* sign-switched). This is not cosmetical - the
algorithm depends quite a bit on this being consistent.
Additionally, most of the list modifications in CalculateTriangles were
wrong (didn't reprocess last triangle for ascend shadowing, and the descend
case was removing the wrong triangle). I admit the old code was probably a
bit too tricky with how it handled "i", so I attempted to refactor it to
make it less easy to screw up in future.
Useful e.g. for ingame scripting when you want to grant extra construction plans. Additionally, this kind of behavior is known from some other functions with per-player parameters like e.g. Sound().
CreateObject() now does not reposition an object after it has been created, but rather grows it around the center of said object.
To that end a new parameter has been added to DoCon() and SetCon() and the documentation has been updated.
When taking damage, clonks will now search and attack enemies even if outside their dedicated guard range. This should help for clonks that fell down from their guarding post.
Renamed CreateObject() to CreateObjectAbove() and replaced all occurrences in script files.
Added CreateObject(), the function may need a rewrite though, see comment in code.
Updated documentation
Auto-detecting UPnP might fail when CMake was invoked multiple times.
This would result in a broken build because the compiler would not find
<natupnp.h>.
With this change, an additional rectangle is stored in C4FoWRegion that
represents the area covered by the viewport in fractional floating point
coordinates. This allows the light texture to be created for an arbitrary
portion of the landscape, and the coordinate transformations for the
shaders will still work.
Also, since the additional rectangle uses floating point precision, the
computed coordinate transformations do now give the exact same result as for
the landscape pixel-by-pixel, and there should not be any offsets left.
I also hope that this change improves or fixes the single-pixel-lines of sky
that are sometimes seen at the edges of the viewport.
