Ok I think I got the the square being clicked.
Now something fairly hard, at least for my knowledge.
I have a couple resources joined with json query from another solved question from here Combining Data to Get Consumer Sales
So.
Assuming i have some data, i can have something occupy a x,y location. Only one data source can occupy a square: crops.location or furniture.location on the same row of data.
I need to change the image grid to reflect the new data that i imprint onto the default map.
Need guidance on that.
