Hello. It’s been years since the last time I used GDevelop and I’m using Unity now.
For what I remember, what I did was to rotate the zombies to face the player slowly then add force towards where the zombie are looking. Pathfinding was just using areas to alter zombies direction.
I presume that GDevelop still doesn’t support collisions for pathfinding since you have a similar problem like I had.
The best solution I can think of right now is to create an empty/invisible “tracker” object with pathfinding behavior that follows the player. Then create a Zombie that follows that tracker through physics.
TLDR
Create an invisible object that follows the player by pathfinding.
Make the zombie follow that object through physics.
