a395a90759 Fixed mapping the PG-9021 which, on Linux, emits a button partway through the trigger press along with axis motion all along the pull 2017-01-20 16:40:11 -08:00

4938c5054e Added SDL_JoystickGetAxisInitialState() to get a joystick axis' initial value.
This is useful for controller mapping programs to determine an axis' zero state

082132a70c Fixed binding the D-pad on some Super NES style controllers
Fixed a case where partial trigger pull could be bound to another button

There is a fundamental problem not resolved by this commit:

Some controllers have axes (triggers, pedals, etc.) that don't start at zero, but we're guaranteed that if we get a value that it's correct. For these controllers, the current code works, where we take the first value we get and use that as the zero point and generate axis motion starting from that point on.

Other controllers have digital axes (D-pad) that assume a zero starting point, and the first value we get is the min or max axis value when the D-pad is moved. For these controllers, the current code thinks that the zero point is the axis value after the D-pad motion and this doesn't work.

My hypothesis is that the first class of devices is more common and that we should solve for that, and add an exception to SDL_JoystickAxesCenteredAtZero() as needed for the second class of devices.

21cb42d79b Make sure we go all the way back (within the XBox controller dead zone) to prevent accidentally binding axes inverted 2016-12-27 09:51:58 -08:00

6d7da0887d Split controller axes into positive and negative sides so each can be bound independently.
Using this a D-Pad can be mapped to a thumbstick and vice versa.
Also added support for inverted axes, improving trigger binding support

0c5e7a1067 Fixed handling joysticks that send multiple events for a single control, e.g. both a button and axis event for a trigger.

0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
