Most of Fortnite Speeder's functionality is handled by config.txt, but there are some useful things you can do with scripts. Let me know if there are any commands you would like added.
Dynamically Adjust Recoil
[113]
keys=rc-20|dbg % recoil set to -20|tcp|2d|s100|1d
endkeys=2u|1u|rc0|dbg % recoil set to 0
repeat=0
Hold down F2 to set recoil adjustment to -20, target the closest player to the crosshair, hold down right click, and then hold down left click to fire. This script assumes you have the aimbot set to either left click or right click (because we are holding down both keys, it doesn't matter). It also assumes you have your trigger/firing key to set to left click. When you release F2, the aimbot will stop, and your recoil adjustment will be reset to 0.
