You did not have a creation/spawn interface at all, nor any actions that spawn/create.
The way you use that tilemap is a no no.
I have no idea what you want to do. So i played with the project. Showing picking, containers and instance variables.

I learned from the passed that nothing happens with this sort of examples. But hey, thats fine to.
The basics are simple tough.
An event is one piece of conditions and actions.
The actions run if the conditions are true.
The actions run on the objects picked by the conditions.
Actions that address an object that is not picked by the conditions, run on all instances of that object.
Sorry, i cant help you skipping all the basics and advance in 1 step from nothing to a super advanced user.
I still call myself beginner.
