I'm making a custom npc (smbx2)

[smbx2 level editor]

I'm making a custom npc, but the custom npc doesn't go back
Now I can walk custom npc
How can I make a custom npc bounce when it hits a wall?

That functionality is the default behaviour. To not get it you have to be doing something wrong. Show your code, please.

You set speedX to -0.6, which is always left. Try 0.6 * v.direction to make it adapt to facing direction (either -1 or 1).

I didn't walk after adding
How do you use it?

Did you put it like that?
v.speedX = 0.6 * v.direction
