How do I load a battle animation on a map?

I downloaded some nice animations for saves, treasure, etc from Hadecynn's site but I'm not sure how to use them on the world/outside maps. Any insight would be greatly appreciated, thanks.

use the event command "Show animation..."

I strongly suggest you take a day off from your regular game development just to check every event command available in the engine to learn what commands exist - it's almost impossible to complete a complex game if you don't even know what the events can do, and you now had several questions that are solved by simple event commands that were always intended specifically for those functions, like calling the savescreen on events designated as save points or now the command to play animations on the map.

I tried the show animation but it didn't see to work, thats why I asked.

What did you set it to?
If it doesn't work you've made a mistake, show us a screenshot of the event where you tried to use the command.

Here is a SS, I couldn't find an example of what it should look like so I just tried my best. RPG Maker is not intuitive if you haven't used it before so a lot of this most likely isn't going to make sense to me for a while. I'm working through a series of tutorials I've found but often the authors assume you know more than you do which leaves me asking seemingly noob-like questions. VXAce had a lot of unencrypted games that could be referenced but I haven't come across any for MV yet.

Somehow it seems like you didnt set the event command to wait for the animation to finish (there should be a check box for it in the animatiom event command itself), in that case your event will continue to the save screen almost "instantly"

Also, just in case you still dont know it, if you hover your mouse to most items in the database and the actual setting box of event commands they show helpful tooltips.

Thank you, adding a wait command did it. Is there a way to make an animation keep running continually on a map?

You'd need to call it over and over, there's no quick fix for that. :)
