What layer does Spawn Object use?

The spawned object goes to the same layer as the spawner by default. Override by adding a layer parameter to System > Create Object, or setting the Spawn Layer Option on the object in its properties.

Why does my bullet spawn behind the wall?

The shooter is on the “Background” layer. Spawned bullet inherits that layer, drawing behind walls on higher layers. Spawn explicitly on the “Gameplay” layer using System Create Object.

Spawn Object vs Create Object difference?

Sprite → Spawn Object creates at the sprite’s position on the same layer. System → Create Object lets you specify position and layer explicitly. Use System for full control.

Fix: Construct 3 Spawn Action Creates Object on Wrong Layer

Quick answer: Use System → Create Object with an explicit layer parameter, not Sprite → Spawn Object which inherits the spawner’s layer.

Player on layer “Background” fires bullets via Spawn Object. Bullets appear behind walls drawn on “Foreground”. Spawned objects went to the player’s layer; you wanted them on the gameplay layer.

Spawn vs Create

Two actions for instantiation:

Sprite → Spawn Object: creates at the sprite’s position on the same layer. Convenient but no layer control.
System → Create Object: explicit X, Y, Layer parameters. Use when layer matters.

The Fix

On player shoots:
    System Create object Bullet on layer "Gameplay" at Player.X, Player.Y

Bullet appears on the gameplay layer regardless of player’s layer. Z-order correct relative to walls and enemies.

Default Layer Property

If you always want a specific object on a specific layer, set it on the object itself:

Select the object in the Project bar.
Properties → Spawn Layer Option = “Custom”.
Set Spawn Layer = “Gameplay”.

Now Spawn Object on this object always uses the Gameplay layer.

Layer Index vs Name

You can pass a layer name (string) or index (int). Names are stable across reordering; indices change. Always prefer names for cross-layout consistency.

Verifying

Shoot a bullet. Inspect the bullet sprite in Play mode; it should be a child of the Gameplay layer in the debug inspector. Visually: bullets should draw in front of background but behind UI.

“Spawn inherits layer; Create lets you specify. For multi-layer scenes, use Create.”

Audit Spawn Object usage when adding new layers to a scene — previously-correct spawns may end up on wrong layers post-restructure.
