this will help you to change values for stuff. wether it is a rocket that goes backwards or a wheel that goes faster than light. i will teach you how to change the values for blocks!!!!

step 1:make machine and save.
step 2:click load button.
step 3:click the little line of text under the "search machine" thing.
step 4:a page will pop out with all your machines save files.
step 5: open your machinesfile with note pad.
step 6: you will end up with something like this:

<?xml version="1.0" encoding="utf-8"?>
<!--Besiege machine save file.-->
<Machine version="1" bsgVersion="1.3" name="testing">
<!--The machine's position and rotation.-->
<Global>
<Position x="0" y="6" z="0" />
<Rotation x="0" y="0" z="0" w="1" />
</Global>
<!--The machine's additional data or modded data.-->
<Data />
<!--The machine's blocks.-->

step 7: find the block you want to change.
step 8: edit the speed or weight. it is easy to find since it will have a 1 in front of it.
step 8.5: if you want to edit size, find the z/x/y scale and edit.
step 9: save the file.
step 10: load your machine again.
step 11:enjoy your crazy new machine!

1:new blocks placed by you will apear at the bottom of the list
2:copy the example file and paste it in a note pad, than open with besiege, and you will get a speed 555 cart!!!
3:remember to subscribe my machines!!!
