Automated Bitmask Converter!

[Yummy]

Hello Everyone, I decided to make another useful script. This script takes a long (4 bytes) as an input, then puts it into binary. Then, you can type in a byte number (1-32) and it will change that byte automatically for you. And, the best part is, there's no need to worry about little endian. Just type the long in from hexedit, then click convert, then change whatever byte the HMT plugins tell you to change.

There are some bugs I think, so please tell me of them.

This is great! This is going to help me so much. Thanks alot, Yummy

what does this thing...change?

[Yummy]

HAHAHA Mr. Blocked my Posts.

It changes bitmasks.

Btw, you're welcome GZ

[spida]

You are one useful person yummy. Thanks for all the help.

As a humble n00b, may I ask what bitmasks are and what they do. Please dont say search it.

[spida]

here srry it is making you search but this is what taught me what they were.

Alright, bitmasks.

I have disabler's tutorial....let me post that.

Code: Select all

About bitmask32's and how to edit them (plus a tutorial on how to walk on walls) by Disabler

A bitmask32 is 4 bytes long. 32 bits equal 4 bytes (32 bits / 8 bits (see below) = 4 bytes). Most things in Halo are in little endian format so you need to reverse the bytes, but if you hex edit then you probably already knew that.
Example: 41 F8 05 CB becomes CB 05 F8 41

There are 8 bits in each byte. The 8 bits together is 1 binary number which shows up as hex in a hex editor.
Example: CB is 11001011 in binary.

Each bit is like an answer to a yes or no question. For example: "Do you want the Master Chief to be able to climb walls as if they are ladders?", 0 would mean no, 1 would mean yes. Each bit is a boolean.

Now, if you're not going to be changing random bits and seeing what happens, you'll want to know how the bits are numbered (or at least in the plugins).

The first byte (when reversed!) contains bits 1 thru 8.
Example: CB, the first byte in "CB 05 F8 41", becomes 11001011,
1 1 0 0 1 0 1 1 (bits/binary number)
1 2 3 4 5 6 7 8 (numbered bits)

The second byte contains bits 9 thru 16 in the same way. The third 17 thru 24. Fourth 25 thru 32.

So when you see a <bit> tag in a plugin, go to the bit after the tag (<bit>26</bit>) and change the bit (don't change the bit tag! Change it in the map you're modding) to 1 for yes or 0 for no.

Now when you're done changing the bits; convert the binary number(s) back to hex, replace the byte you were editing, reverse the bytes so it's in little endian format again, paste it into a hex editor, and save.

Here's how you get the Master Chief to walk on walls. (Lots of steps, but most of them are very short and simple.)
1. Open the map you're going to mod in HMT (Mac, of course).
2. Click on the arrow beside "bipd".
3. Click on "characters\cyborg_mp\cyborg_mp".
4. Look to the right side of HMT. Copy the number to the right of "Meta: ".
5. Paste the number into a calculator already set to use Hexadecimal.
6. Open a bipd.xml plugin and look for <type>bitmask32</type><offset>0x2F4</offset><name>Flags (it might have another name in other plugins)</name>
- Copy the offset (2F4).
7. Switch to the calculator and click on the add (+) button.
- Paste.
- Click on the equals (=) button.
8. Copy the new number.
9. Open a hex editor.
- Use the Go to tool and paste.
10. Now copy the next 4 bytes. This is the bitmask32.
- Paste them somewhere else (TextEdit or whatever).
11. Reverse them as shown in an example somewhere further up the page.
12. Copy the fourth (last) byte. It should be 02.
- Convert it to binary.
13. You should now see 00000010. Switch to the plugins and look for <name>Can Climb any Surface</name> (or something similar).
- Right above that line of text it says <bit>26</bit>. Bit 26 is the second bit, going left to right, in your binary number, 00000010.
14. Change the number to 01000010 in some program (even TextEdit). You just enabled walking on walls.
15. Paste it into whatever you use to convert bases, and convert it to hex. The hex number should now be 42.
16. Replace the fourth byte (Step 12) with the number you got earlier (42).
17. Copy the four bytes and paste them into your hex editor, replacing the four you copied earlier (Step 10).
18. Save and quit.
- Open Halo and play the map you modded. Enjoy ;)

I love writing tuts :D
You need a way to add hex and convert hex to binary. I use PCalc 2, but it's shareware.

Should I make a less detailed tutorial? PM me.

[Chaos Barnaby]

Thank you guys, this community is alot easyer to deal with since last time i was here thanks to you two, Yummy and spida, as well as a few others.

Great tut by the way, thanks to whoever made it, it helped quite alot.

[Yummy]

haha thanks, that would be disabler. Apparently he used to be active here, then he disappeared?

EDIT: My program does steps 11 through 16...which are the hardest steps. So, all you need is to copy the bytes, click convert, then type 25 in the change a bit box....then click change. Then, it puts the changed value in that text box...so select the new bitmask value and copy it into Hex.

[spida]

Yea mods will start to become the same and boring soon. That's why people need to share information with others so then we can create better mods by becoming smarter in modding. Like the spawn points map and tutorial is friekin awesome!!!!

There is a MUCH simpler way to do this. WAY wasier.

Go into hexedit, Go to 91DFA8 and change the byte to C2.
Save, Done.
This is probably exactly what you would get doing all the steps you posted. XD

[spida]

Yes, but that is for wall walking and immune to falling. 42 is just for wall walking. I was up all last night editing bitmasks and such. It was fun and this is a very useful program.

[>Shadow<]

Definetly agreed.

Making floating people is funny too. XD

[spida]

I love bitmasks. They are so fun. Floating people? Is that bitmask?
