How do change the sprite when entering Area2D?

How do I change a character's sprite when it enters an Area2D (for example, so that the character's sprite looks sad/scared/angry/bored)?

I think it's pretty easy, bruh.. just change the player's state to the ANIMATION state (or the GIMMICK state if you're using the Player Refactor) and play the animation you want through the player's animator

This is a pretty good early explanation, but let's back up a little since we don't know yet where MasterGlitcher is in the process or what his exact intentions are.

@MasterGlitcher2006

Is your intention simply to have the player stand still and play an animation of the character frowning/smiling/scowling/falling sleep for a little bit before resuming? Is this sprite change already set up in your animation player?

If so, Quartz is spot on. You'd most likely write a script to change the player's animation to whatever the name of the animation you are wanting is after changing the player's state to animation/gimmick (depending on your branch). Then either after a certain time interval or after whatever trigger you want to act on, that same script should just change the character back to the normal state and that will let that state take back over the player animation.

If what you want is something more elaborate, we'll need to know exactly what it is you want to do.
