Mars Marine - Spawning AI Characters - AI Despawns after loading in

[3HourGames]

I’m working through the first Unreal Blueprints course on the third section - Mars Marine.

I’ve made it through to the Spawning AI characters section, and for some reason whenever I spawn an enemy alien spider, it immediately despawns. It never makes it to the viewport, but in the World Outliner I can see that AI Controller and BP_Alien Character are in fact being created and immediately destroyed (Tried to attach video and it’s not allowed).

What I’ve done:

• Ensured that Auto Possess AI is “Placed in World or Spawned”
• Checked all my “Is Alive” functions to make sure I’m not killing the alien as it spawns.
  Attached screenshots of all functions created in this lecture. Let me know if you’d like to see any other graphs.

One thing to also check is to see if your spawn points are a little too low to the ground. The default response from the SpawnActor node when it spawns an actor is to immediately despawn if that actor is going to be colliding with another actor.

You can change this response with the “Collision Handling Override” in the node.

I couldn’t find Collision Handling Override, but raising the spawn points did keep the enemies from de-spawning. Thank you for the answer!

You’re welcome!

For “Collision Handling Override”, take a look at the first screenshot in your OP.
