Northy Presents: A Block Replacer Mod

Looking to update an old ship with new DLC blocks, but hate the though of manually replacing every block? Or do you just want to replace all turrets with another type in one(two) click(s)? Maybe you just want to convert all Light armor to heavy armor? Look no further!

This mod will make replacing blocks a breeze!

So, what does it do: It instantly swaps one block type for another, while keeping the rotation and color. You can also manually rotate a block before replacing it, as some blocks have a different default rotation compared to the block you are replacing. You can also replace all heavy armor with light armor and vise versa

I was updating some old ships and wanted an easier way to replace all old hydrogen thrusters for the newest DLC ones without going through them one by one, thus this project was born.

Controls: Hold a welder and hold Left Ctrl. Let go of Ctrl and the welder behaves normally again. Press Ctrl and you resume where you left off.

| Left-click | Step 1: pick the block type to replace. Step 2: pick the block type to replace it with | | Right-click | Go back one step (or leave armor mode) | | Shift + click | Only the grid you clicked, not the whole mechanically-connected ship | | Middle-click | Cycle armor mode: off, light to heavy, heavy to light | | Ctrl + Z / Ctrl + Y | Undo / redo (last 5 replace actions) | | Numpad 4 / 6 | Rotate the replacement about the block's up axis | | Numpad 8 / 2 | Tilt the replacement back / forward | | Numpad 7 / 9 | Roll the replacement | | Numpad 5 | Reset the extra rotation |

Red outlines show every block that will be replaced. Results appear in chat.

Known Bugs: - When replacing blocks that are in a group or on a toolbar, they will need to be remade. The Mod API simply cant restore them. Chat messages tell you if that does happen.

Other Notes: - Not tested in MP - Not really tested with modded blocks or armor.

Also, the "Change Notes" on the right side under the thumbnail is always updated when I do changes!

Note: Claude was used as a tool to create the script.

Enjoy.
