Running System depending on tool

Help and Feedback Scripting Support
#1

I know there are already other posts about shift to run. But hear me out, I want to set a custom running animation and a custom walking animation. The running/walking animation will depend on the user’s weapon. Right now I only scripted a custom running script but it doesn’t change depending on the tool yet. I wanna know two things, is it fine my approach on a custom running animation and how should I set the different walking animations and running animations depending on the tool that is active. Keep in mind I wanna make the transition between animations very smooth. Thank you !

As for “how to set the different walking animations and running animations depending on the tool that is active?”. This is probably the most straight forward way to detect when a player is holding the tool actively.

Context: This script is located as a child of the tool so script.Parent = tool

-- For detecting when the tool is equipped
script.Parent.Equipped:Connect(function()
	print("Player is holding the tool")
end)

-- For detecting when the tool has been unequipped
script.Parent.Unequipped:Connect(function()
	print("Player has unequipped the tool")
end)

Based on this, within each function, you can do whatever you’d like, like trigger an event that modify’s the walking/running animation, and such. You should be able to use this info to connect your custom script but let me know if you need further assistance.

Alright, thanks but I was more wondering if my approach to create a running system is fine. It seems kinda weird to have to script 100 lines just to make a running system. Is it considered normal what I did with the code? Is there a more optimized way or doing it?

This needs to be moved to init(), because it won’t work after respawn.

Yes

Your code is clean, don’t look for microoptimisations unless there’s a huge problem with the performance of it (there isn’t)

You’d be surprised!
