Two things
1.)when my animation plays it just makes a white box over the character
2.)when my box that emits things emits the mister the mister goes out a little bit then disappears

Without even looking, I can probably answer your questions. (Besides, you didn’t post a link lol)

White animation boxes are called “buffer blocks”, at least, I call them that. All that it means is that you have to press play, and refresh the page or hit F5.

Quick disappearing emitted objects are usually a simple cause. Edit the emitter, then check the “doesn’t expire” box, or whatever it’s actually called. Now the object won’t destroy after the timer.
