2015-04-11Clear mouse events caused by mouse warp.Simon Howard
SDL_WarpMouse() can create mouse events that are later interpreted as user mouse input. Thanks Super6-4 for this fix.
2015-04-10Strip out SDL_VERSION_ATLEAST #ifdef conditionals.Simon Howard
These were added ages ago as hacks to make the code compile with SDL2, back when SDL2 was still in development. They aren't relevant any more and aren't useful - the actual SDL2 port is proceeding on sdl2-branch.
2015-02-20Refactor config file API.Simon Howard
The config file API previously relied on binding config variables using M_BindVariable() which took a void pointer. It occurred to me that if used on a boolean variable, this would be erroneous, but the void pointer would make it impossible to tell. Split this into separate M_Bind{Foo}Variable() functions based on type, which allows for proper type checking on the pointers that are passed. Vaguely related to #509.
2014-10-25Remove 1280x1000 scaling.Simon Howard
We already have 1280x960, which is the correct aspect ratio. This means that when running at 1080p the windowboxing borders will be slightly thicker, but if we're already showing borders anyway, it's better to at least use the correct aspect ratio. This fixes #460. Thanks to Doom_user for asking about this on Doomworld: http://www.doomworld.com/vb/post/1316735
2014-10-19i_video: fix an if condition in my previous commitMike Swanson
`else if (f == 'w')` doesn't really secure itself against uninitialized memory, it still needs to test that `s == 3`.
2014-10-19allow -geometry to specify fullscreen or windowed modes, like PrBoomMike Swanson
This allows strings like "640x480w" to cause the engine to run in a window, while strings like "1280x800f" cause the engine to run in fullscreen mode. This is inspired by the behavior of the PrBoom -geometry parameter.
2014-05-05Clean up file headers.Simon Howard
This change rewrites and simplifies the copyright headers at the top of all source files: * Remove "Emacs style mode select" line; this line was included in the headers for the originally released source files and appears to be to set the file type for old versions of Emacs. I'm not sure entirely why it was required but I don't think it is any more. * Remove "You should have received a copy of..." text from copyright header. This refers to the old 59 Temple Place address where the FSF headquarters used to be located and is no longer correct. Rather than change to the new address, just remove the paragraph as it is superfluous anyway. This fixes #311. * Remove ---- separator lines so that the file headers are barer and more simplified.
2014-04-12video: Change default for screen_bpp to 0.Simon Howard
Some machines don't work well with 8-bit screen depths any more. It's better to default to just using the machine's native color depth instead. Change the default to 0 (for SDL_SetVideoMode this means "use native color depth"), auto-adjust to native color depth on startup if screen_bpp=0 (so that debug messages at least make sense) and document for the config file value that a value of zero means "use native".
2014-04-01Replace all snprintf() calls with M_snprintf().Simon Howard
The Windows API has an _snprintf function that is not the same as Unix's snprintf(): if the string is truncated then no trailing NUL character is appended. This makes the function unsafe. Define a replacement/wrapper called M_snprintf that works the same but always appends a trailing NUL, for safety on Windows and other OSes that behave like this. Do the same thing for vsnprintf(), and update HACKING to list snprintf/vsnprintf as forbidden functions. This fixes #375; thanks to Quasar for pointing out the different behavior of these functions.
2014-03-30Eliminate some uses of sprintf() from common code.Simon Howard
As part of this, add DIR_SEPARATOR_S as a string version of the DIR_SEPARATOR macro. Change M_TempFile() to return a string allocated on the C heap rather than the zone heap. This is a first step towards fixing #371.
2014-03-28video: Fix calculation of -devparm ticker.Simon Howard
The released linuxdoom source had the devparm ticker dots at a spacing of two pixels rather than four pixels (as used in Vanilla Doom). In commit 4a31ec8fcee20e.. I changed this back to four pixel spacing, but forgot to multiply the number of tics to adjust as appropriate. Fix this so that the dots are calculated just like Vanilla Doom is. Thanks to _bruce_ for pointing this out on Doomworld, and to Alexandre-Xavier for questioning my reasoning when I wasn't convinced that the current behavior was wrong. This fixes #360.
2014-03-27video: Fix crash when running fullscreen with -2.Simon Howard
Remove special logic for setting a scale factor (2x, 3x, etc.) when running fullscreen instead of windowed. This fixes a crash due to the fact that I_GraphicsCheckCommandLine() is called before SDL's video subsystem is initialized. This makes -2 identical to -geometry 640x480, which is arguably a better (more easily comprehensible) behavior. Thanks to Fabian Greffrath for reporting the bug. This fixes #338.
2014-03-27Define a keyboard scan code for PrintScreen.Simon Howard
There is no real scan code for the PrintScreen key under DOS, but it is convenient to be able to bind it as a screenshot key. Define a "fake" scancode (126) to represent PrintScreen so that it can be represented as a key binding in configuration files. Also add some comments/notes to the scantokey[] lookup table. This fixes #369.
2014-03-17Allow for PNG screenshots.Fabian Greffrath
2014-03-16video: Center mouse when grabbing cursor.Simon Howard
When releasing mouse grab (activating menu etc.) we move the mouse cursor to a non-distracting location at the bottom-right of the screen. But this was causing abrupt jerks in mouse movement when re-grabbing the mouse again. Center the mouse when turning on grab so that this doesn't happen. This fixes #283.
