Title: Prefab to 'see' game object in scene.
Post by: curb47 on September 27, 2020, 10:40:54 AM

Hi there,

I'm trying to streamline my logic, and I have an enemy floating alien (rigid body, physics) that uses the Look At (game object - player spaceship) action, with Add Force so it moves towards to player spaceship.

I've turned the enemy alien thing into a prefab and I'm using a pool to spawn them at certain trigger points, however, when the pooled clone is spawned, the Look At action no longer has the game object - player spaceship parameter.

I've looked into it, and am I right in understanding that a prefab can not 'see' a gameobject, prior to spawning? Like, you can't reference a game object from the scene in an action on a prefab?

I've tried using game object variables too, but nothing seems to work.

Does this make sense?

Many thanks,

J.

Yu can put scene objects on prefab. You have to use variable to set it.
What i usually do is, Use "get Owner" action and save Player prefab on global variable. then, mention that variable in prefabs

Hi.
after you spawn a prefab you can use 'Set Fsm' actions to set data on the prefab.

For example if the spawned prefab would be a enemy and it would need to reference the player.

Then After spawning (store the spawned object in a variable)
Use 'Set Fsm Game Object' and target the spawned object.
and as variable set the Player gameobject to the target variable.

Maybe this video can help :
