TweakMB (With Fire & Sword support!) [v5.09; updated 12.29.13]

Users who are viewing this thread


TweakMB: A Mount & Blade Tweaking Utility

Mount & Blade tweaking made easy!  TweakMB provides an easy-to-use interface for activating and modifying gameplay tweaks in Mount & Blade, Mount & Blade: Warband, and Mount & Blade: With Fire and Sword.  This includes things such as modifying tournament bet amounts, village improvement build times, party sizes, and much more (see below for a complete list).  You can make as many modifications as you want within the program, then save all of them at the same time.

Using TweakMB is very similar to modifying the module text files manually, but TweakMB automates the entire process (meaning it's much easier and faster to use), and also reduces the chances of user error.  The pre-release versions contain only a limited selection of tweaks, but the number of tweaks supported will continue to increase with future releases.

What mods does TweakMB support?

Awesome! This has saved me alot of time from going through files and editing them myself! Suggestion is it possible to add something to change the amount of money, or renown that you get from finishing a quest?

I'm glad you like it  :grin:  It's certainly possible to add those tweaks, but it probably won't be added for quite a while simply due to the huge amount of time it would take.  Every part of every quest has completely separate values for money, experience, reputation, etc.  Adding reputation, for example, is relatively easy since the reputation value for each quest is always preceded by the same thing in the text file.  On the other hand, money and experience are a bit more difficult, simply because they're not always concrete values (ie, the amount can differ depending on how many cattle you delivered, how many troops you trained, etc).

Nonetheless, I'll probably get it added at some point, but don't hold your breath for the time being  :mrgreen:
Add an option to enter and remember custom tweaks in the form of
<tweak begin>
replace <string1> in <file1> with <string11>
replace <string2> in <file2> with <string22>
<tweak end>

for future use and easy adding of new ones.

EDIT: btw, you can easily add custom variables into such custom tweaks, so that people not go inside actual strings for the second time (trying to recall what was that particular place inside the string) if they want to change one particular number

And make those tweaks exportable so that people can share and aggregate those is an obvious further development :smile:
A new release was uploaded today.  A couple of new tweaks are now supported, including two of my favorites (adding the "Meet with village elder/guild master" options to the menus).

The next release will focus on adding Warband support!

0.2 (03.28.10)
- Added icons to the Load and Save buttons
- Changed "Mayor Quests" to "Guild Master Quests"

The following tweaks are now supported:
  • Max prisoners gained per point of leadership
  • How much prisoners are sold for
  • Allow Tavern Keepers to buy prisoners from you
  • Add "Meet with Village Elder" to village menu
  • Add "Meet with Guild Master" to city menu
How does this work with Muffins?

I've noted that some of the old script.txt changes still work but others don't.

Edit re-reading the topic and my own thread I realise that this tool does indeed support.."muffins".

That is quite honestly the least amusing april fools joke i've come across to date.
Any chance of adding an option to remove companion interaction? (So we can have any combination we want to without the constant threat of them leaving..)

Good app by the way. Thanks for the effort.

think you can add reputation tweaks for lords and stuff to it for warband?

I think that can definitely be done.  However, it may be a while, simply due to the number of ways you can earn reputation with lords (mainly the sheer number of quests).  It's actually something I'm working on right now!
