THE orbital arrow cannon datapack.
Ever wanted an orbital arrow cannon datapack that feels good?
How to use:
/function railgun:give_rod
Command in chat to get a fishing rod and just aim where you wanna shoot and it will do a nuke shot of arrows at the location just like wemmbu's version of the osc.
/function railgun:radius/1 trough 10
This command will change the radius of the shots, pretty straight forward.
/function railgun:payload/r 1 trough 10
This command is used to shoot a shot without the fishing rod, change the value tp change the payload ammount.
Others debug command:
/function railgun:cast_start
/function railgun:cast_step
/function railgun:load
Highly inspired by cubic metre and wemmbu
