Ho I fix Invalid get Index 'global position' (on base: 'Timer')

dkn616

I'm trying to create some kind of endless shooter and I've copying the GDScript from this video. It works just for a few seconds because the scene pauses itself and sends me back to the editor, It shows me an error on the debugger area, and I don't know what maybe causing this.

The script is exactly the same, only difference are files names's. but EnemySpawner scene makes the game pauses and returns me to the editor, and the debugger console shows me this

I've been trying to fix it, the scene keeps pausing itself randomly, and I have to manually resume the scene, idk what causes this.

enemy or spawn_position[index] is a Timer instance. And I assume you want it to be Node2D. Check in the debugger objects you compare.

Is the Enemy class a Node2D? It probably is, so I think your issue is that get_children() call. This gets all the children of that node, which can be anything. One way to solve this is to check that the child is an Enemy.

spawn_position = []
for position in $SpawnPositions.get_children():
    if position is Enemy:
        spawn_position.append(position)

The "enemy" is a 2D Area with its own scene, and the spawner is a Node2D wich also has it's own scene. The "child's" are just the positions for the spawner , wich uses position 2d class.

The index is there to make the spawner works, cuz it needs a timer. If I reemplace it with Node2D the scene don't launch correctly.

Apparently I just had to delete and add the Timer again, then re-write that last part of the code. It seems the problem has been solved for now. The scene stoped to pause it self.

In any case, thanks for the help! I feel a bit more comfortable now to ask here next time. I'm kinda new to Godot and GameDev scenario. So I'm glad to joined here.

Awesome! So glad you figured it out.
