You need to use variables.
Turn, it can have a value of 0 or 1 (0 = player, 1 = CPU or the other way around, whatever you prefer).
Moves. Store how many moved the player has made.
Once the player move change the Turn variable from 0 to 1, so the enemy can do their move. You will also have other events that are connected and maybe groups to enable/disable.
When it's time for the enemies to move, just limit their movement to the variable "Moves". Each time the player moves in his turn by one tile, you increase the variable by 1.
When the enemy's turn ends, you change again the "Turn" variable and set the variable "Moves" to 0.
