How to mod Halo 3 .map files on a retail xbox 360

Now that modding is possible with a jtag'd xbox I've been doing some modding. Ive mainly been using alteration(Xenon7.com/files/programs/alteratio...ration_0052.rar) I've been looking around and it seems there is very very little on actually modding halo3. So I've started this forum in hopes that people start messing around with alteration and discuss what they did and how they did it.

Please, read the next few lines!!!!

---->This is all done on a RETAIL xbox.<----

You only can mod on JTAG exploited xbox.
I am not going to explain this here. There are many tutorials, here is a good one. (Complete Guide To Installing Xbreboot For Noobs - Scenyx Entertainment Community)


You CANNOT move files from map to map.

Some maps do not have all the things I talk about. If you don't find something, its either your plugins(Try to find the most up to date plugins), or your map isn't compatible.


With that said, I've been using alteration and its pretty powerful.

In alteration there is a "Editors tab" next to a "Documents" tab. For most modding (at least so far in my experience) you do it in Editors --> Meta Editor. Then you select the tag on the left that you want, so possibly [weap] objectsweaponassault_rifleassault_rifle. And that opens up all information on assault rifles.

Most of the map names are here. I might add my own list if i get some time.

Alteration has a lot of unknown values that you can change, the creator of alteration never intended for it to go public so he didn't make it idiot proof. Your going to have to experiment with all the different values if you really want to. They will change stuff, it just doesn't say what. YOU CAN MESS YOUR MAPS UP, so back them up. As a matter of fact you ARE going to mess your maps up if you are messing with stuff, which is good, just make sure you back up. But now for more of the tut part.

Saving is a pain on alteration. If your under the assault rifle tab and want to compare something to the BR tag. You MUST click save at the bottom before you switch tabs or the properties will switch back. Although you can make multiple tabs to switch back and forth, in which you don't need to save each time. You will find this out the hard way.

There is an "Show Invisibles" This will show more values, some labeled some not.




VEHICLE MODS



How to make a Warthog really fast:
1.) Go to [vehi] objectvehicleswarthogwarthog
2.) In the Meta Editor scroll down to Motion Properties
3.) Mess around with these settings, but i found that on sandtrap these are good settings: Unknown (Turning Related) 1.4, Max Left Turn 0.9599311, Max Right turn -0.9599311, Turn Rate 6.283185, Horse Power? 5000, Vehicle Speed 60, Human Vehicle Weight 0.25, Covenant Vehicle Weight 1.
4.)Now I'm not sure how much this changes things but i put "Fraction of Total Mass" to 10 in "Friction Points". Again feel free to mess around with it.
5.)Now if you run it like that and hit something(Which you will. TRUST me.) the game will freeze up because of the current collision detection method. So go up to the top and where it says "Collision Damage" "cddf" "globalscollision_damagevehicle_medium" change it to "globalscollision_damageinvulnerable_harmless"
p.s. This doesn't make your warthog invulnerable in any way, it just reacts like it is an invulnerable.
Also, you can do this with elephants and stuff, but the values are way different.




How to Make Anything Drivable:

THIS ONE IS NOT MINE! I do not take credit for it. It's pretty hard to do, but really cool.

WEAPON MODS



How to Make an Assault Rifle Shoot Elephants:

Before I go on, I would like to say, this is how you change ALL!! projectiles. Follow this tut if you want to change BR shooting grenades, or Snipers shooting Spartan Lasers. Just change the values, with alteration its VERY easy.
1.) Go to [weap] objectsweaponassault_rifleassault_rifle
2.) Go down to "BARRELS"
3.) Find "Projectile"
4.) Change the first drop down menu to vehi and the second to objectslevelsmultishrinebehemoth
behemoth
p.s. Be careful with this, shoot to many and you will freeze your xbox lol.

2.)Go to "NEW TRIGGER"
3.)Find "Behavior"
4.)Change to spew.
5.)Go to "BARRELS"
6.)Find "Fire Recovery Time(Seconds)"
7.)Change that value to 0.
8.)To fire faster, change "Rounds Per Second"



How to Have Unlimited Ammo:

1.) Go to [weap]--> the weapon you want.
2.)Go to options at the very bottom.
3.)Click "Show Invisables"
4.)It will reload. After that find "MAGAZINE"
5.)Change "rounds total initial", "rounds total maximum", "rounds reloaded", "Max Rounds Held" all to whatever you want to be.
6.)NOTE!!: Since it is an in16 you cannot chose a number higher then 32768 or it will crash.(that goes for all int16 values)

4.)Go to [matg]
5.)Select globalsglobals

This is what this thread is about. This is a discussion forum. I would really like people to post there ideas on mods. No matter how basic or advanced. If you post how to do it. Ill move it up and give you credit for it.

Here are some things I would like to see:

1.)Flying, obviously haha. There is a flying check box in biped but it just makes you stand still. You can go into the monitor and move but when you come out you just stand there. So if some people were to mess around with that, that would be pretty cool.

2.)Change the acceleration of vehicles: I'm sure i'm just missing something and this is pretty easy to do. But make it so the elephant doesn't start out going 1 mph. I know there is an acceleration scale, but changing it doesn't seem to effect anything.

3.)Removing/Ignoring Invisible Walls: Find what makes invisible walls exist, or just how they behave and change it?




Now for the fun part, you all download alteration, start messing around with it and post your tuts here and ill move them up to my post, if I can keep up with this thread.

Feel Free to leave a Thank if you like the thread.
And if this gets helpful and big enough, wouldn't mind it getting stickied. :tongue:

Lets have some fun!

I didnt say you could. I said most of what he had wanted to know was very easy and was done before. And I helped him through aim rather then showing him a pic of a meta editor when he asked to know how to make a weapon full auto. :wink:

Yes, you can only mod offline, but they are working on removing the 30ms ping limit from system link. And making a network called kai link (i think). Then everything will be allowed, even halo mods. I'm not sure how match matching will work...i doubt it will, but custom games will. And thats when the real modders come out :smile:

I don't THINK with kai you can do matchmaking. Matchmaking probably has some connection to microsofts live connection. I don't know but i only think. But personally i hope you cant do matchmaking. It would be so stupid over kai link. You would never be able to get in a game becasue EVERYONE would be bridging to use there mods.
