Top-Down Building

I’m making a top-down Construction based survival Area for my Game where the Player has to defend against waves of Enemies but also build a Suitable Base that can help Them with this
Basically Im using a tileset (Not Tiled but the One made in the Engine) basically when the player has enough resources they can craft a wall and wherever they place it, the ground changes from grass to the wall
Please Help

You’ll need to describe the problem you are facing. All you have given is a brief explanation of your game, but not what you need help with.

The Problem I’m experiencing is I made an Event that says When There is Currently 5 Clay in inventory it should allow you to place Bricks
Like change a Tile with a New One since both the bricks and grass are in the same tile set
Another problem is I want it to be able to where you the block placing only works if you have enough clay

Can you provide screen shots of the events related to these problems?

I can’t really since I ended up removing the Events to focus on the More important Parts of the Area
