Saitek p2500 (Cyborg Rumble Force Pad) has a D-pad, two analog sticks, and numerous buttons. SDL 2.x on OSX detected everything except the right-side analog stick. The right-side stick is considered a 'simulation device' with the axes mapped to throttle and rudder.
The patch adds support for throttle and rudder on the HID simulation page.
We needed a bit, so we're hoping no one needs this effect, especially when
it's fairly close to SDL_HAPTIC_SINE, we hope.
SDL_HAPTIC_LEFTRIGHT maps to XInput's functionality, so this removes the SINE
code for the XInput driver to keep things clean.
This also makes the simplified Rumble API use SDL_HAPTIC_LEFTRIGHT if
SDL_HAPTIC_SINE isn't available, to keep XInput working.
When we break the ABI, and can extend the supported capabilities field from
a Uint16, we'll add SDL_HAPTIC_SQUARE back in.
This patch is based on work by Ethan Lee.
To fix this we need to ignore the alpha channel in the colorkey comparison, which is the way colorkey comparisons are defined in SDL.
We also need to reset the alpha and color modulation when converting a surface.
If the user is using their context from a non-main thread, we could be
calling -[NSOpenGLContext update] on our thread, while they were
accessing it on their thread.
With this change, we schedule updates when the event comes in on the
main thread, and act on them when the user calls SDL_GL_MakeCurrent or
SDL_GL_SwapWindow.
This uses a better mouse grab if you define SDL_MAC_NO_SANDBOX. This
mouse grab uses CGEventTapCreate, which you cannot access if you have
sandboxing enabled.
From Sythical:
Hello, I've created a simple SDL2 application which draws a texture on the screen. The problem I'm having is that if I launch another program which loads the UAC popup or if I lock my PC and then login again, the application stops drawing the texture. I tried adding SDL_Delay(10000) after SDL_RenderPresent(renderer). This made the texture stay on the screen for a little bit but the texture wasn't drawn again after the delay. Here's my code:
#include "SDL.h"
int main(int argc, char *argv[])
{
SDL_Renderer *renderer;
SDL_Window *window;
SDL_Surface *surface;
SDL_Texture *rect_texture;
SDL_Event main_event;
SDL_Rect rect_data;
int enable_vsync = 1;
if(SDL_Init(SDL_INIT_VIDEO) < 0) return 1;
window = SDL_CreateWindow("SDL2 Application", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 600, 600, SDL_WINDOW_RESIZABLE);
renderer = SDL_CreateRenderer(window, -1, enable_vsync ? SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC : SDL_RENDERER_ACCELERATED);
SDL_SetRenderDrawColor(renderer, 20, 20, 30, 255);
surface = SDL_LoadBMP("icon.bmp");
rect_texture = SDL_CreateTextureFromSurface(renderer, surface);
rect_data.w = 32; rect_data.h = 32;
rect_data.x = 300; rect_data.y = 300;
while(main_event.type != SDL_QUIT)
{
SDL_PollEvent(&main_event);
SDL_RenderClear(renderer);
SDL_RenderCopy(renderer, rect_texture, NULL, &rect_data);
SDL_RenderPresent(renderer);
}
SDL_DestroyTexture(rect_texture);
SDL_DestroyRenderer(renderer);
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}
This prevents a rogue call to SetWindowPos() from changing the state unexpectedly.
Also moved the size correction code above the window position query, because the initial window size can affect the positioning.
Anisotropic filtering is meant to be used for textures at a stark
angle, not perpendicular to the camera.
