I’d like to create a 2D game where an enemy continues to walk or jump once the players stand on it.
This is the behaviour of the enemies in the sample Godot project (2d platformer - kinetic). In my game, however, the enemy stops completely once the player is on top.
I’ve compared the code between the sample game and mine, and I can’t figure out what is different (except that I use move_and_slide and not move_and_slide_with_snap inside player.gd, because for me, move_and_slide_with_snap caused the player to stop responding to input.
This is my very first Godot project, so I’m still learning the ropes. (I’ve been coding for years, so I am familiar with a number of concepts.)
Here is the enemy.tscn file
