 Posted: Mon Aug 23, 2004 9:19 pm Post subject: a little derelict.sdl.mouse (fix?) |
 |
|
hello. I've been using derelict sdl and I've been using
if(SDL_GetMouseState(null, null)&SDL_BUTTON_RIGHT)
// right mouse button is down, do right mouse button stuff
well, the problem is the right mouse button doesn't seem to be clicking, that is until I changed
const Uint8 SDL_BUTTON_RIGHT = 3;
to
const Uint8 SDL_BUTTON_RIGHT = 4;
in derelict.sdl.mouse.d
and then the right mouse button works.
Anyone else have this type of problem? I'm no SDL expert but i've tested this 'fix' in both linux and windows and it works. So it's good for me, it just doesn't make much sense numerically (doesn't follow the +1 scheme).
Anyhow, good luck to Derelict I hope to see derelictAL in the future!

ps. I havn't figured how the WHEELUP WHEELDOWN works so I don't know if it messes that up or not. |

The problem is not the constant, but the way you are using SDL_GetMouseState. Revert SDL_BUTTON_RIGHT to its original value and try this:
| Code: |
if(SDL_GetMouseState() & SDL_BUTTON_RMASK)
...
|
I haven't documented anything in Derelict because documentation for everything is available elsewhere. SDL_GetMouseState does not appear to be in the SDL docs, but there is commented in the c header that the SDL_BUTTON macro should be used. SDL_BUTTON_RMASK is defined as SDL_BUTTON(SDL_BUTTON_RIGHT), which is the same thing. I took the liberty of leaving the SDL_BUTTON macro out of mouse.d (I don't like converting macros to functions unless absolutely necessary). One day I suppose I need to get around to documenting the differences, because there are a few.

Heh, is that a hint?  |

ok. yea i don't like those macros that much anyway.
