Here's the setup:

A simple cargo "platform" elevator in a shaft with doors on the wall only (not a "typical office building" type) that goes between two levels. In the elevator shaft are a button at each level that move the elevator between levels. Outside the shaft is the call buttons, one at each level.

Here's what I've got so far:

func_train: name: cargo, first stop target: cargopc1

func_door: name: cargodoor1

func_door: name: cargodoor2

path_corner: name: cargopc1, next stop: cargopc2, fire on pass: cargodoor1

My question is what is the easiest way to set up the call buttons so that it will move the elevator to the current level? Or just open the doors if it's already at the current level? I think it's an env_global but I'm not quite sure how to set this up. It's rather confusing to me. Also, is there a way to check the up/down buttons so that whatever level the elevator is at, the other button doesn't do anything?

I could just grab a prefab, but that really doesn't teach me anything (not to mention I'd have to edit it anyway)

Guidance would be appreciated on this. Thanks.

Here is one possible setup; it may not be the most efficient, depending on what you want to do, but it should work:

button1 and button2 both target a multi_manager, mm.  mm is the entity that determines "what happens when either call button is pressed".

Here is what mm does:

It triggers the train/door/whatever once, so that it moves between the two positions.  That means that if the lift is down, it will go up, and if it's up it will go down.  In a similar way, it toggles the doors at the top and bottom (one closes, one opens).  It also triggers an env_global called global1 and another env_global called global2.  global1 has a "global state to set" of "b1state", and global2 has a state to set of "b2state".  Both globals have the flag "set initial state" ticked.  You also need two multisource entites, multi1 and multi2.  These are set to read the global states "b1state" and "b2state" respectively.

Let's say that button1 is the call button that will be active when the level starts.  Then you want to set global1 to be initially on, and global2 to be initially off.

Finally, set button1 to have a master of multi1 and button2 to have a master of multi2.

Each time a button is pressed, it turns it's own global off and the other one on.  The effect is for the button to disable itself and activate the other one.
