How do I make the player switch to idle animation when stopping and destroy a tree when attacking?

1. How do I make the player switch to the idle animation when the player stops running?

2. How can I make the tree get destroyed when the user presses the space bar (to attack)?

Can you stop posting the same two questions again and again?

Your character already switches to idle animation. And if you want an answer to the second question, you need to explain it better.

I'm clearly stated my problems

1. it already works

2. Add Line of Sight behavior.

On Space pressed
Player has LOS to tree : Tree destroy
