How do I make a moving enemy?

So I'm making a game and I want to make an enemy that can move around passively until you jump on it. Once you jump on it, it disappears kinda like a goomba in Mario. I also want to make it stop at the edge of cliffs. The only way that I can think of to make the jumping action work is to move the hitbox/collision box to the top, but then there is no way for the enemy to kill the player. One other problem I'm having is the enemy keeps falling through the platform. Is there any way to do this? Thank you.

Create a new empty sprite object, make it invisible and for each enemy pin this empty sprite on top of it and use it to compare if player jumped over the enemy.

Thank you very much! Do you know how to make the enemy moving?

There are more than one way but try this:

Use an instance variable to handle the enemy state, for example: moving_left, moving_right

Compare this state and move it using a behavior like 8 directions.

Use invisible sprites do change the enemy state like:

On colision with "sprite movement helper" if enemy.state = moving_left set it to moving_right else set it to moving_left

Thank you very much! You have helped me a ton with the development of my game. If you want to play it here it is: construct.net/en/free-online-games/smiley-run-33919/play

Ok, so I made an enemy, but I want to have multiple enemies in the same level. Is there any way to do this with the same sprite? whenever I try to do it with the same sprite, it incorrectly pins it because it is pinning it to the wrong enemy. Thanks!

You have to pick the enemy that you want to pin.

We have a bunch of conditions to pick objects.

See it here

construct.net/en/make-games/manuals/construct-3/system-reference/system-conditions

You can do for example:

On Created (enemy)

Pick last created

Spawn a new lifebar on position enemy.X, enemy.Y-20

Pin lifebar to the enemy
