What i am trying to achieve here is to build the construction 1 time and to not be able to build anymore; when i try to build the second one to say You can have only one ( bo matter how many times i click.
Create a boolean variable and set it to true whenever you place the unique actor. Use a branch whenever you click the button with the condition as the boolean variable that is set to true when you build it. If it is true, you can print the message, but if it’s false, you can place the actor.
Another way to do this is to create an integer variable and increment it whenever you place it. When you click the button to place the actor, run a branch as the condition as checking if the integer is greater than, or equal to 1. If it is, print the message. If it isn’t equal to 1, place the actor.
Hope this helps! Cheers!
Something else you could do is get all actors of class, and from that get a for each loop (Or for each loop with break) and from the array index get a greater than or equal to and put that into a branch. If it is true print the message, if it’s false, place the actor.
PLZ tell me if this doesn’t work. Cheers!
