Problems with placing walls

[MangoMan]

So I'm working on a top-down shooter, and while the player is pressing shift, it creates a wall if the player is not overlapping another wall, so that walls can't be on top of each other. That's what I'm trying to do, but it's not working. For confirmation, here's what I tried:

I made an event making sure the player is not overlapping a wall while shift is pressed.
I made an action for that event that creates a wall at the player's position.

It only works when I take away the overlapping part of the event, but then the player is constantly making walls while shift is pressed, which looks ugly. Any help please?

It works for me.

* Repeat while shift is pressed
+ [Negate] Player is overlapping Wall
- Create Wall at 0,0 from Player

Hmmm... That's pretty much what mine looks like, I just have a couple other events inserted, but it doesn't create a wall no matter what. Any idea why it's not working for me?

Popcorn, That's what I would have done too. Can you post your example for MangoMan. Maybe there's something missing in his code.

Do you want to see my game? I can attach it. Here (this is my first posted attachment so forgive me if I did it wrong). Line 3 is the problem.

MangoMAn,..I looked at your game and what are you looking to do with it. I did read you first post but really don't understand what you're looking to do. Nothing seems to be working,.well the movement of the ship is and shooting the object,.but as for creating your walls it isn't working at all from me. Even if I disable line # 3. Maybe we can come up with something else to get this done.

It's pretty much going to mostly be a two player game, and both players can set up walls to give themselves cover from the other player, and to protect their generators, which give more energy. Energy is used to shoot, place walls, and place generators. The first player uses Q and E to change weapons or structures. Shift shoots or places the structure that is selected. So it's kind of a strategy/action game.
Back to the walls problem. I want it to be more easy for the player to lay walls by holding shift and moving. For example, if the player moves from top to bottom of the screen, walls are laid behind him as he moves, eventually creating a column of walls.
As of now (if I take away the overlapping event), if the player holds shift to make walls, he runs out of resources too fast, and like I said, it looks ugly.

I hope you understand my problem better now and you can help me out more.

Never mind, I figured out that it works to see if the wall is not overlapping the player instead of if the player is overlapping the wall. Thanks for your effort!
