Through research, tinkering and the help of a really nice defold forum user, @rama , I have implemented an enemy spawning system.
However, I really don’t think the way I am spawning the enemies is efficient. I basically randomise a game object to spawn to, and spawn it accordingly. Here is the layout of the game object spawns:
The code works fine, it’s really good (once again, thank you rama!), however there must be a better way to get positions? Do I need game objects?
Hi there 
If i understand you correctly, you randomly choose one of these 6 spawn points and get it’s position to spawn the current enemy to?
Then i think this solution is absolutely fine and efficient if you just want these 6 fixed points in your level.
Yes, correct. Is having game objects inside a game object efficient?
Have you thought about factory.create to dynamically create your enemies? You could create as many enemies as you want when you want.
Yes it is. Gameobjects themselves are very very cheap, they are basically just folders in this regard.
