A Stick wrote:How did you get a server on Mac?

My first server was hosted in a VM on my mac, and given a bridged connection in the VirtualBox settings so that I could properly port forward. Trying to mess around with Wine was just too much work when I already had an ISO of windows XP for a VM.

My current one is a dedicated Windows 7 box that I had an extra of.

If you want any help setting up a server, feel free to PM me.

With the new version of SAPP available, gravity is a mutable value that can be changed on-the-fly by an admin.

As of now, there is no way to support syncing this change with HaloMD clients, as the HAC2 changes that allow server-client gravity syncing are not available to use on Mac in its current form, nor does the dev on HAC2 seem to have any interest in working on support for HaloMD.

I was hoping someone with experience writing plugins for HaloMD, or in making changes to MD in general, could comment on the feasibility of such a feature, if there is any work planned to incorporate it, and if not, could provide more information on plug-in development.


I am a software engineer myself, and would be interested on working on this problem, but as of now have no experience with HaloMD's source code, or it's plugins. Any guidance would be appreciated.

Best,
Drake

[09:31:39] <Zero2r> oh
[09:31:50] <Zero2r> well I did write a plugin that allows one to set an arbitrary gravity constant
[09:33:05] <Zero2r> by default it's 0.997 G (well it's 1/3.048/30/30 world units per tick squared)
[09:33:31] <Zero2r> 10/3.048/30/30*
[09:34:07] <Zero2r> basically if you're in the air, it subtracts that much from your Z velocity every single tick
[09:35:08] <Zero2r> if you're talking about the gravity constant thing
[09:35:38] <Zero2r> it's easy to find. bit slicer can easily do the job by monitoring your Z coordinate
[09:36:17] <Zero2r> I gave this information to sehe who incorporated it into SAPP. I don't know how it communicates with HAC2, so that's what needs to be found
[12:10:41] <Zero2r> oh it doesn't communicate with HAC2
[12:10:56] <Zero2r> as I suspected, btcc22 never actually added the feature to hac2
[12:10:59] <Zero2r> it's just an anticheat feature

I don't have a template plug-in project right now with me, but you can look at the build settings for the plug-in targets. If you Reveal Mods in Finder, and go up a folder or two, there should be a couple directories for installed plug-ins.

002 informed me that btcc22 didn't add a feature to HAC, but I don't know how the gravity thing works, or why the value needs to even be synced.

002 wrote:I poked around in Bit Slicer for you. You'll find the gravity constant at 0x37B600 in Bit Slicer. It's a 32-bit floating point number.

It's equal to about 0.003565 world units per tick squared. Basically, this number is subtracted from every objects' and particles' Z velocity every tick while in the air.

If you want to convert this to meters per second squared, 1 world unit equals 10 feet which equals 3.048 meters, therefore 1 world unit equals 3.048 meters. 1 ticks is 1/30 of a second, so 1 tick squared equals 1/900 seconds squared. Up to you on how you want to deal with this constant, really.

If anyone knows how SAPP announces changes to the gravity variable to clients, that information would make this plugin one step closer to complete

Guessing it could be through the chat system. Anyway seems like an appropriate question to ask the SAPP folk.
