📋 About This Mod
What is Chassis Editor?
Chassis Editor is a simple tool that allows users to modify chassisdef json files without the hassle of json formatting! Most fields of the chassisdef file can be modified, though not all. Users can select a single file and modify it, or they can select a directory to have a batch of files all modified in the same way.

Inventory Slots - The in-game GUI won't show the new slots, but you can drag new equipment to the list and it will add it.
Max Rear Armor - I have put rear armor on every location, but I haven't been certain that the armor is used in combat.
Internal Structure - Be careful with this one! Could render mechs in your bay "damaged" to an incredible degree (46/1000 looks pretty damaged to the game)
Hardpoints - Add/Remove hardpoints to any location! Load up missile slots on the legs to unleash a wave of Infer-knees!
Batch Editing
Users can choose a directory and batch editing will apply all the saved changes to every chassisdef file in that directory (including all sub directories). Once a directory is selected, users generate a list of changes by modifying UI elements and clicking the "Save change" button. A new entry will appear in the change list to the right, allowing the user to verify the change and remove it by clicking the "X" button if necessary. If the user creates more than ten changes, scroll buttons will appear and allow the user to continue managing their change list.
Once all changes have been done, the user can click the "Apply changes" button to apply all of the changes to the chassisdef files!
User can choose if they would like a log file regarding the batch edits (per file indication of success or failure and exception reason) to be generated in the chosen batch directory.
