I would appreciate any explanation or if you need more info, just @ me

anyone able to help? well i’ve reached a stump

if you already have the boomerang script, you could calculate the angle at which it is coming in at, then get he perpendicular angle to it and change the force, it is really dependant on how you have made the script in the first place

ye ig but i’m planning on creating another script to cater to the boomerang
