hi folks,

One of my students is developing a Torque game on the Mac. We soon found out that joystick support for the Mac seems non-existent.

While looking at the problem in greater detail, I came across this in macCarbInput (line 93):

ConsoleFunction( isJoystickDetected, bool, 1, 1, "Always false on the MAC." )
{
/*
argc; argv;
return( DInputDevice::joystickDetected() );
*/
return(false);
}

Have GarageGame actually written joystick support for the Mac literally out!
This is relatively straight forward to fix, so I'm curious as to why it hasn't been done yet?

Also, what is the roadmap for moving the Mac version of TGE away from Carbon and onto Cocoa??

And what exactly is this blog about? Try the forums if you want to ask questions.

David,

Implementing joystick support on the mac should be relatively simple. I seem to recall seeing quite a few articles on ADC mentioning implementing joystick / gamepad support into games, so you should probably start there.

Sadly, i've not seen many mac games support joysticks/gamepad's :(

@David, I would ask on the mac forums here and see if Paul S. can shed some light on that.

lol I've just been officially "hushed" by GG. I didn't think what I said was bad at all. It was the truth and I was polite enough about it. Looking back I can see how it could have possibly started some stuff in here though. Good call I guess.

While my original intention was to query the support for joystick on the Mac, it seems to me that the Mac-side could do with a blog to discuss ways of further enhancing TGE (and other GG apps) on the Mac platform. So I would welcome any input, whether it be on the specifics of the joystick or more general Mac development.

BTW, the real underlying problem with the Mac 'port' is that it is inherently Carbon based. GG should consider, or inviting others, to assist with a Cocoa version.

Any thoughts??

I think the main reason they chose carbon over cocoa is because Carbon is C based while Cocoa is Objective-C based. While you can use Cocoa from C++ from what Ive read you need a Objective-C++ layer in there.

hi Tim,

this shouldn't be a problem - many developers integrate C/C++ in Object-C and/or Objective-C++. However, before I proceed with this thread I am checking out the latest version in CVS so that I know what changes are being made.

A lot of mac changes have been made in TGE 1.5 which is not available yet. So you may want to wait for its release.

Hi Tim,

I have downloaded 1.5 and am currently testing it. Apart from a number of comments being cleaned up and some changes, there has been no progress with the Joystick input.

Is there a diff file somehwere showing the differences between 1.4.2 and 1.5?
