made an animation but i want to find the ID so i can use it again but i cant figure out where is it.
Since youre asking this you may be new to ROBLOX in general. So ill attempt to be specific as possible.
You need to go to the actual Roblox site. On the top of the screen, you select develop. Once there you find the animations tab and select your animaton. Then the URL in the top of the screen in the search bar has a 8 or 10 or something digit code. Copy the code and that is the Animation ID the code on the top of the screen. Just the numbers not the rest.
Go in your profile, then in inventory and then in animations and select the one you created. Easy buddy!
