Support Gamecheats halo 3 ai playground, change bsp/map?

[MrEmu 0]

Greetings! I recently got into halo 3 modding and Assembly (I used to do biped switches when I was a kiddo on halo CE, so I always knew the basics lol) 

I have experimented with many maps, but none were ideal to me besides GameCheat13's ai playground. I really enjoy the map but I heavily dislike the lack of atmosphere (just being in a giant box, made of sand) I want actual terrain rather than a giant box. 

Upon checking my scnr file I did find the BSP for sandbox in gamecheats playground (the original halo 3 map) and I really wanted to switch over, despite matching up the default sandbox.map' s scnr and the ai playground scnr for sandbox I couldn't get the map to actually load this way. I tried replacing files form the original sandbox file but even doing that had no avail. Is there any possible way to switch over this map? I really love the scripts and everything else besides the BSP of the map. I would love more terrain and atmosphere. 

Before anyone copy pastes me the BSP injection guide and the .map modding basic guides. Yes I have looked at these, and no they didn't help with what I am trying to do. (Should go without saying since this is why I am posting though.) I am open to anything otherwise. Thank you in advance!

Dont bother injecting anything such as BSPs as you'll very quickly hit a file size limit.

You be better off starting from scratch and either porting or writing the scripts yourself in a new map. 

If you want to make AI spawners just use an effects, see gamecheats setup for examples.

Thanks man! In my case I noticed gamecheats map file still had bits of sandbox, (in which swapping some things didn't end up well) in my attemps to actually port over the maps (I tried both char and the effe tags) I however ended up with 10gb in tags, in which I can already see is going to be very unfortunate. Seems like it's not even worth the work at this point

You need to isolate the tags you want, injecting a BSP is not just a right click extract/inject process. Go check zedd's tutorial on the matter.

null out tags the char and effe tags refer to that you dont need, right?

The BSP tutorial can still help, just follow it in reverse up to where the new bsp gets injected. Open a clean sandbox to get the original block offsets for stuff as you go, assuming they were swapped out in ai playground and not edited in-place.

Back with an update, switched out the 020_bsp_010 (I believe it's called) and tried importing the sandbox file that was still there. Had zero luck, followed the tutorial from  Part 6: Fixing Stuff  to  If your BSP was the first in the map, continue reading here:  and I still am at a black screen. I might be outta luck it seems.  I have also tried adding the original SBSP from sandbox.map and pointing stuff towards that. No luck. 

 

Edit: just compared scnr files/ added anything missing. Still no luck.

Anyone?

I had this Idea a few days ago but am out of memory for how it works, in fact, I've never done a BSP injection myself. It would actually be neat though to see a different level other than the desert box, such as an oasis or maybe The Covenant like gamecheat does his AI battles on...

iirc this map was pretty low on extra memory, I had to cut a few AI enemies because of this. So im not sure how well it would deal with another BSP.

[Akarias 250]

Speaking of memory, has anyone looked into this recently? The only way I have gotten around it is to load a MP map in the SP engine mode or taking a MP BSP into a SP map. Is it due to data streaming?

Yeahh, I was hearing about the whole issue with the memory etc. My big thing is wanting a terrain, starting to realize it's more troublesome than it's worth. Rather new but I have had luck with just about everything else I have attempted besides BSP swapping. If you're okay with me asking what're you using for ai battles? The terrain from the covenant would be something awesome to use.
