I’m not sure how I could simplify this to make it one line of code

Make a function, add a number parameter (type)  
if type = 0  
then make iron  
if type = 1  
then make gold  
the set wall and set empty can’t be in the function because location can’t be a parameter

one way to combine the code for those two projectile events is to combine the tiles themselves and use the arcade-tile-util extension to make them _look_ different. the arcade-tile-util extension has several “cover tile” blocks that let you disguise one tile as a different one.

for example, take a look at this code:

 ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/c/cd74dc2ea81cc8af234cc2edaeaccce62b893f82.png)

this game has four breakable tiles (each of the four colors). when the tilemap is loaded, i loop over each breakable tile and cover it with itself while replacing the tile _underneath_ with a different tile. then, i only need overlaps code for a single tile since they are all actually the same underneath.

also, in the overlaps code you need to clear the covered tile in addition to setting it to transparency. that’s the last line in that event block

here’s a link to that code:

@Harmanuary if you want to do walls, swap the overlaps event with an “on hit wall” event and check the tile inside, like so:
