I've been experimenting at lot with how to organize my entity parent objects for flexible future use in other projects.

At the moment, I'm playing around with having state functions in a separate script, and storing their ID in a simple array, calling them with script_execute. I'm finding I like this because it lets me open the states script in a side window to the object's event window, as a way of accessing and see Step Event codes, unlike, say, a switch statement that would need to be scrolled up to see or hidden in a region.

Create:

state = ENTITY_STATES.NORMAL;


states[ENTITY_STATES.NORMAL] = functionStateNormal; 

Step:

script_execute(states[state]);

I wish GM still let you store functions in enums.

What's your personal code style at the moment for states?
