Subject: SDL for Macintosh Programmer's Workshop: removed dynamic loading
I'm working on a game called D2X which uses SDL, and I recently ported
it to Mac OS 9. I used MPW to build it. It uses OpenGL. To get it to
work, I had to build SDL so it doesn't dynamically load OpenGL. This is
because I don't think MPW supports dynamic loading. The following patch
makes sure when SDL is built under MPW, dynamic loading of shared
libraries is disabled.

The value returned by \fBSDL_JoystickGetAxis\fP is a signed integer (-32768 to 32768) representing the current position of the \fBaxis\fR, it maybe necessary to impose certain tolerances on these values to account for jitter\&. It is worth noting that some joysticks use axes 2 and 3 for extra buttons\&. .SH "RETURN VALUE" .PP Returns a 16-bit signed integer representing the current position of the \fBaxis\fR\&. .SH "EXAMPLES" .PP .PP .nf \f(CWSint16 x_move, y_move; SDL_Joystick *joy1; \&. \&. x_move=SDL_JoystickGetAxis(joy1, 0); y_move=SDL_JoystickGetAxis(joy1, 1);\fR .fi .PP .SH "SEE ALSO" .PP \fI\fBSDL_JoystickNumAxes\fP\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 23:00
