I don't if that is possible. Because the "newline" command must be outside the string:

"first line" & newline & "second line"

You could use an Array with the numbers to define each enemy, and when that kind spawns you remove that number from the Array.

Are you using different Sprites for each enemy? Why don't spawn the Sprite instead of using the Family? Then you will be sure to spawn them only once.

I would go with the Text Box object, like Jubalicious87 described.

I guess you can use a very big number like 99, so it will send the object to higher layer before 99.

It would be nice if the array object had a text box for each dimension. So I could edit the array using "[a, b, c, d]".

Another trick is adding a "Trigger once while true" condition.

I don't think so. They must have their own servers to save player's data. What they do is register player's info using Facebook ID. Pretty much like game on Clay.io do.

You can create or move an existing object to any layer using a string with the layer's name.

System > Create object.

Object > Move to layer.

I agree with LittleStain. You should have two variables (pos X & pos Y) and change them accordingly.

I guess that will do the trick. I am already using a dummy sprite to control the character. Thank you so much. =]

I am using pathfinder to move my character in an isometric game. But I need to mirror the character depending on the direction he is walking. Any ideas?

I wouldn't do that. I would take a look and then maybe give you some hints. But sometimes is better do find your way to do what you gotta do.
